# ⚡️ Quick Start: Scene Indexing with VideoDB
<a href="https://colab.research.google.com/github/video-db/videodb-cookbook/blob/main/quickstart/Scene%20Index%20QuickStart.ipynb" target="_parent"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"/></a>
This guide provides a quick introduction to scene indexing with VideoDB, enabling powerful visual search and content understanding in your videos. Leverage vision models to extract meaningful information from videos and easily index it using VideoDB.
Use scene indexing to build RAG applications and answer complex queries:
## Setup
---
### 📦 Install VideoDB
Install the VideoDB package using pip:
```python
!pip install -U videodb
```
### 🔑 Configure API Key
Import the `os` module and set your VideoDB API key as an environment variable. Replace `"sk-xxxx-yyyyy-zzzz"` with your actual API key.
```python
import os
os.environ["VIDEO_DB_API_KEY"] = "sk-xxxx-yyyyy-zzzz"
```
### 🌐 Connect to VideoDB
Establish a connection to VideoDB and get a collection instance:
```python
from videodb import connect
conn = connect()
coll = conn.get_collection()
```
### 🎥 Upload Video
Upload a video to VideoDB. This example uses a YouTube video URL.
```python
video = coll.upload(url="https://www.youtube.com/watch?v=LejnTJL173Y")
```
## 📇 Index Scenes
---
The `index_scenes` function automatically indexes visual information in your video, extracting meaningful scenes.
```python
index_id = video.index_scenes()
```
### Optional Parameters
Customize scene indexing using optional parameters:
* **`extraction_type`**: Choose a scene extraction algorithm (e.g., time-based).
* **`extraction_config`**: Configure the selected extraction algorithm (e.g., time interval for time-based extraction).
* **`prompt`**: Provide a prompt for a vision model to describe the scenes and frames (e.g., "describe the image in 100 words").
* **`callback_url`**: Specify a URL to receive a notification when the indexing job is complete.
Refer to the [Scene and Frame Object Guide](https://github.com/video-db/videodb-cookbook/blob/main/guides/video/scene-index/advanced_visual_search.ipynb) for more details.
```python
from videodb import SceneExtractionType, IndexType
index_id = video.index_scenes(
extraction_type=SceneExtractionType.time_based,
extraction_config={"time":10, "select_frames": ['first']},
prompt="describe the image in 100 words",
# callback_url=callback_url,
)
# Wait for indexing to finish
scene_index = video.get_scene_index(index_id)
scene_index
```
Example output:
```
[{'description': 'The image depicts a man sitting in an office or conference room...',
'end': 10.01,
'start': 0.0},
{'description': 'The image shows a man with a receding hairline, wearing a dark suit...',
'end': 20.02,
'start': 10.01},
...
]
```
> Note: It may take a few seconds for the index to become available for searching.
```python
# Search your video using the index_id.
# Default Case: search all indexes
# query: "drinking"
res = video.search(query="religious gathering",
index_type=IndexType.scene,
index_id=index_id)
res.play()
```
This will output a URL that opens a VideoDB player, showcasing the relevant scenes.
## ⚙️ Understanding `index_scenes` Parameters
---
Let's explore the parameters of the `index_scenes` function in more detail:
* `extraction_type`: Chooses the algorithm for scene extraction.
* `extraction_config`: Provides configuration details for the chosen algorithm.
* `prompt`: Instructs the vision model on how to describe each scene.
* `callback_url`: Specifies a URL to be notified when the indexing job finishes.
### ⚙️ `extraction_type` & `extraction_config`
Videos are essentially sequences of images (frames). The `extraction_type` parameter allows you to select different scene extraction algorithms, which, in turn, influence the selection of relevant frames for description. For more information, see [Scene Extraction Algorithms](https://docs.videodb.io/scene-extraction-algorithms-84).
### ⚙️ `prompt`
The `prompt` is crucial for guiding the vision models. It defines the context and desired output format.
For example, to identify running activity, you might use the following prompt:
> "Describe clearly what is happening in the video. Add 'running_detected' if you see a person running."
For experimenting with custom models and prompts, see [Advanced Visual Search Pipelines](https://github.com/video-db/videodb-cookbook/blob/main/guides/scene-index/advanced_visual_search.ipynb).
### ⚙️ `callback_url`
The `callback_url` receives a notification upon completion of the scene indexing process. Refer to [Callback Details](https://docs.videodb.io/callback-details-66#_lubHL) for more information.

## 🗂️ Managing Indexes
---
> 💡 You can create multiple scene indexes for a single video and rank search results based on these indexes.
**List Scene Indexes:**
`video.list_scene_index()` returns a list of available scene indexes, including their `id`, `name`, and `status`.
```python
scene_indexes = video.list_scene_index()
print(scene_indexes)
```
Example output:
```
[{'name': 'Scene Index 2024-07-22 10:06', 'scene_index_id': 'f4db35c5ce45a709', 'status': 'done'}]
```
**Get a Specific Index:**
`video.get_scene_index(index_id)` returns a list of indexed scenes, including `scene_index_id`, `start`, `end`, and `description`.
```python
scene_index = video.get_scene_index(index_id)
print(scene_index)
```
Example output:
```
[{'description': 'The image depicts a man sitting in an office...', 'end': 10.01, 'start': 0.0},
{'description': 'The image shows a man with a receding hairline...', 'end': 20.02, 'start': 10.01},
...]
```
**Delete an Index:**
```python
video.delete_scene_index(index_id)
```

```python
# 📌 VideoDB F1 Race Search Pipeline (Turn Detection & Metadata Filtering)
# 🎯 Objective
# This notebook demonstrates how to use scene-level metadata filtering to enable precise search and retrieval within an F1 race video.
# 🔍 What We’re Doing:
# - Upload an F1 race video.
# - Extract scenes every 2 seconds (1 frame per scene).
# - Describe scenes using AI-generated metadata.
# - Index scenes with structured metadata (`camera_view` & `action_type`).
# - Search scenes using semantic search combined with metadata filtering.
# 📦 Install VideoDB SDK
# Required for connecting and processing video data.
```
```python
!pip install videodb
```
```python
# 🔑 Set Up API Key
# Authenticate with VideoDB to access indexing and search functionalities.
import os
os.environ["VIDEO_DB_API_KEY"] = ""
```
```python
# 🌐 Connect to VideoDB
# Establishes a connection to manage video storage, indexing, and search.
from videodb import connect
conn = connect()
coll = conn.get_collection()
print(coll.id)
```
```python
# 🎥 Upload F1 Race Video
# Adds the video to VideoDB for further processing.
video = coll.upload(url="https://www.youtube.com/watch?v=2-oslsgSaTI")
print(video.id)
```
```python
# ✂️ Extracting Scenes (Every 2 Seconds)
# We split the video into 2-second scenes, extracting a single frame per scene for indexing.
from videodb import SceneExtractionType
scene_collection = video.extract_scenes(
extraction_type=SceneExtractionType.time_based,
extraction_config={"time": 2, "select_frames": ["middle"]},
)
print(f"Scene Collection ID: {scene_collection.id}")
scenes = scene_collection.scenes
print(f"Total Scenes Extracted: {len(scenes)}")
```
```python
# 🔍 Generating Scene Metadata
# To make scenes searchable, we use AI to describe & categorize each scene with the following structured metadata:
# 📌 Scene-Level Metadata Fields:
# 1️⃣ `camera_view` → Where is the camera placed?
# - `"road_ahead"` → Driver’s POV looking forward.
# - `"helmet_selfie"` → Close-up of driver’s helmet.
# 2️⃣ `action_type` → What is the driver doing?
# - `"clear_road"` → No cars ahead (clean lap).
# - `"chasing"` → Following another car (intense racing moment).
from videodb.scene import Scene
# List to store described scenes
described_scenes = []
for scene in scenes:
print(f"Scene from {scene.start}s to {scene.end}s")
# Generate metadata
camera_view = scene.describe(
'Select ONLY one of these camera views (DO NOT describe it, JUST return the category name): ["road_ahead", "helmet_selfie"]. If the view does not match exactly, pick the closest one.'
)
action_type = scene.describe(
'Select ONLY one of these options based on the action being performed by the driver (DO NOT describe it, JUST return the category name): ["clear_road", "chasing"]. If the view does not match exactly, pick the closest one.'
)
scene_description = scene.describe(
"Clearly describe a Formula 1 scene by specifying the scene type, the drivers and teams involved, the specific location on the track, and the key action or significance of the moment. Use concise, yet rich language, targeting Formula 1 enthusiasts seeking precise scene descriptions."
)
print(f"Camera View: {camera_view} | Action Type: {action_type}")
print(f"Scene Description: {scene_description}")
# Create Scene object with metadata
described_scene = Scene(
video_id=video.id,
start=scene.start,
end=scene.end,
description=scene_description,
metadata={
"camera_view": camera_view,
"action_type": action_type
}
)
described_scenes.append(described_scene)
print(f"Total Scenes Indexed: {len(described_scenes)}")
```
```python
# 🗂 Indexing Scenes with Metadata
# Now that we have generated metadata for each scene, we index them to make them searchable.
if described_scenes:
scene_index_id = video.index_scenes(
scenes=described_scenes,
name="F1 Scenes"
)
print(f"Scenes Indexed under ID: {scene_index_id}")
```
```python
# 🔎 Searching Scenes with Metadata & AI
# Now that our scenes are indexed, we can search using a combination of:
# ✅ Semantic Search → AI understands the meaning of the query.
# ✅ Metadata Filters → Only return relevant scenes based on camera view & action type.
# 🔍 Example 1: Finding Intense Chasing Moments
# Search for scenes where a driver is chasing another car, viewed from the driver's perspective.
from videodb import IndexType
from videodb import SearchType
search_results = video.search(
query = "A skillful chasing scene",
filter = [{"camera_view": "road_ahead"}, {"action_type": "chasing"}], # Using metadata filter
search_type = SearchType.semantic,
index_type = IndexType.scene,
result_threshold = 100,
scene_index_id = scene_index_id # Our indexed scenes
)
# Play the search results
search_results.play()

# video.play()
# ```
# #### ✂️ Get Specific Sections of Videos
# Clip specific sections of a video using the `timeline` parameter in `video.generate_stream()`. The timeline accepts start and end times in seconds.
# For example, the following will stream the first 10 seconds and then the 120 to 140 second of the uploaded video.
# ```python
# stream_link = video.generate_stream(timeline=[[0,10], [120,140]])
# play_stream(stream_link)
# ```
# #### 🔍 Indexing a Video
# Indexing enables searching within a video. Invoke the index function on the video object. VideoDB currently offers two types of indexes:
# 1. `index_spoken_words`: Indexes spoken words in the video. It automatically generates the transcript and makes it ready for search. 20+ languages are supported. Checkout [Language Support](https://docs.videodb.io/language-support-79) to know more.
# 2. `index_scenes`: Indexes visual information and events of the video. Perfect for finding scenes, activities, objects, emotions in the video. Refer [Scene Index Documentation](https://docs.videodb.io/scene-index-documentation-80) for details.
# <div style="background-color: #ffffcc; color: black; padding: 10px; border-radius: 5px;">
# <strong>Note:</strong> Indexing may take time for longer videos.
# </div>
# ```python
# # Index spoken content of the video.
# video.index_spoken_words()
# ```
# ```python
# # Index visual information in video frames. You can change the prompt according to your use case.
# # You can index a video multiple times with different prompts.
# index_id = video.index_scenes(
# prompt="Describe the scene in strictly 100 words"
# )
# # Wait to Indexing to finish
# scene_index = video.get_scene_index(index_id)
# scene_index
# ```
# #### Search inside a video:
# Search can be performed on indexed videos using `video.search()`. When searching, you have the option to choose the type of search and index. VideoDB offers the following types of search:
# `SearchType.semantic` Perfect for question answer kind of queries. This is also the default type of search.
# `SearchType.keyword` It matches the exact occurrence of word or sentence you pass in the query parameter of the search function. keyword search is only available to use with single videos.
# `IndexType.scene` It search the visual information of the video, Index the video using index_scenes function.
# `IndexType.spoken_word` It search the spoken information of the video, Index the video using index_spoken_words function.
# ```python
# from videodb import SearchType, IndexType
# result = video.search(query="what's the dream?", search_type=SearchType.semantic, index_type=IndexType.spoken_word)
# result.play()
# ```
# ```python
# # Try with different queries
# # "city scene with buses"
# query = "mountains"
# result = video.search(query=query, search_type=SearchType.semantic, index_type=IndexType.scene)
# result.play()
# ```
# ##### 📺 View Search Results:
# `video.search()` will return a SearchResults object, which contains the sections/shots of videos which semantically match your search query
# * `result.get_shots()` - Returns a list of Shot that matched search query
# * `result.play()` - This will open the video in your default browser/notebook
# ##### 🗑️ Cleanup
# You can delete the video from database using `video.delete()`
# ```python
# video.delete()
# ```
# ### RAG: Working with Multiple Videos
# ---
# `VideoDB` can store and search inside multiple videos with ease. By default, videos are uploaded to your default collection and you have freedom to create and manage more collections, checkout our [Collections docs](https://docs.videodb.io/collections-68) for more details.
# If you are an existing llamaIndex user, trying to build RAG pipeline on your video data. You can use VideoDB retriever. Checkout [llama-Index docs](https://docs.llamaindex.ai/en/stable/examples/retrievers/videodb_retriever.html)
# ##### 🔄 Using Collection to upload multiple Videos
# ```python
# # Get a collection
# coll = conn.get_collection()
# # Upload Videos to a collection
# coll.upload(url="https://www.youtube.com/watch?v=lsODSDmY4CY")
# coll.upload(url="https://www.youtube.com/watch?v=vZ4kOr38JhY")
# coll.upload(url="https://www.youtube.com/watch?v=uak_dXHh6s4")
# ```
# * `conn.get_collection()` : Returns Collection object, the default collection
# * `coll.get_videos()` : Returns list of Video, all videos in collections
# * `coll.get_video(video_id)` : Returns Video, respective video object from given video_id
# * `coll.delete_video(video_id)` : Deletes the video from Collection
# ### 📂 Search on Multiple Videos from a collection
# You can simply Index all the videos in a collection and use search method on collection to find relevant results.
# Here we are indexing spoken content of a collection for quick experiment.
# <div style="background-color: #ffffcc; color: black; padding: 10px; border-radius: 5px;">
# <strong>Note:</strong> Index may take time for longer videos</div>
# ```python
# # for simplicity we are just indexing the spoken content of each video.
# for video in coll.get_videos():
# video.index_spoken_words()
# print(f"Indexed {video.name}")
# ```
# ### Search Inside Collection:
# Search can be performed on a collection using `coll.search()`
# ```python
# # search in the collection of videos
# results = coll.search(query = "Deep sleep")
# results.play()
# ```
# ```python
# results = coll.search(query= "What are the benifits of morning sunlight?")
# results.play()
# ```
# ```python
# results = coll.search(query= "What are Adaptogens?")
# results.play()
# ```
# #### 📺 View Search Results:
# `video.search()` will return a SearchResults object, which contains the sections/shots of videos which semantically match your search query
# * `result.get_shots()` - Returns a list of Shot that matched search query

# 1. `index_spoken_words()`: Indexes spoken words in the video by automatically generating a transcript. Supports 20+ languages. See [Language Support](https://docs.videodb.io/language-support-79) for more details.
# 2. `index_scenes()`: Indexes visual information and events in the video, enabling searching for scenes, activities, objects, and emotions. See [Scene Index Documentation](https://docs.videodb.io/scene-index-documentation-80) for details.
# <div style="background-color: #ffffcc; color: black; padding: 10px; border-radius: 5px;">
# <strong>Note:</strong> Indexing can take time, especially for longer videos.
# </div>
# ```python
# # Index spoken content of the video.
# video.index_spoken_words()
# ```
# ```python
# # Index visual information in video frames. You can customize the prompt to fit your use case and index a video multiple times with different prompts.
# index_id = video.index_scenes(
# prompt="Describe the scene in strictly 100 words"
# )
# # Wait for indexing to finish and retrieve the scene index.
# scene_index = video.get_scene_index(index_id)
# scene_index
# ```
# #### 🔎 Searching within a Video
# Search indexed videos using `video.search()`. You can specify the search type and index type. VideoDB offers the following search types:
# * `SearchType.semantic`: Ideal for question-answering type queries. This is the default search type.
# * `SearchType.keyword`: Matches the exact occurrence of words or sentences in the query. Keyword search is only available for single videos.
# And the following index types:
# * `IndexType.scene`: Searches visual information from the scene index (created with `index_scenes()`).
# * `IndexType.spoken_word`: Searches spoken content from the spoken word index (created with `index_spoken_words()`).
# ```python
# from videodb import SearchType, IndexType
# result = video.search(query="what's the dream?", search_type=SearchType.semantic, index_type=IndexType.spoken_word)
# result.play()
# ```
# ```python
# # Try with different queries
# query = "mountains" # Example query: "city scene with buses"
# result = video.search(query=query, search_type=SearchType.semantic, index_type=IndexType.scene)
# result.play()
# ```
# ##### 📺 View Search Results
# `video.search()` returns a `SearchResults` object, which contains the sections or "shots" of the video that semantically match your search query.
# * `result.get_shots()`: Returns a list of `Shot` objects that matched the search query.
# * `result.play()`: Opens the video in your default browser/notebook and jumps to the most relevant section.
# ##### 🗑️ Cleanup
# You can delete the video from the database using `video.delete()`:
# ```python
# video.delete()
# ```
# ### RAG: Working with Multiple Videos
# ---
# `VideoDB` excels at storing and searching within multiple videos. By default, videos are uploaded to your default collection. You can create and manage additional collections; see the [Collections documentation](https://docs.videodb.io/collections-68) for details.
# If you're building a Retrieval-Augmented Generation (RAG) pipeline on your video data using LlamaIndex, you can leverage the VideoDB retriever. See the [LlamaIndex documentation](https://docs.llamaindex.ai/en/stable/examples/retrievers/videodb_retriever.html) for more information.
# ##### 🔄 Uploading Multiple Videos to a Collection
# ```python
# # Get the default collection
# coll = conn.get_collection()
# # Upload Videos to the collection

# coll.upload(url="https://www.youtube.com/watch?v=vZ4kOr38JhY")
# coll.upload(url="https://www.youtube.com/watch?v=uak_dXHh6s4")
# ```
# Useful collection methods:
# * `conn.get_collection()`: Returns the default `Collection` object.
# * `coll.get_videos()`: Returns a list of `Video` objects within the collection.
# * `coll.get_video(video_id)`: Returns a specific `Video` object from the collection, given its video ID.
# * `coll.delete_video(video_id)`: Deletes a video from the collection, given its video ID.
# ### 📂 Searching Across Multiple Videos in a Collection
# Index all videos in a collection and then use the `search` method on the collection to find relevant results across all videos. The following example indexes the spoken content of each video in a collection for a quick demonstration.
# <div style="background-color: #ffffcc; color: black; padding: 10px; border-radius: 5px;">
# <strong>Note:</strong> Indexing can take time, especially for longer videos.
# </div>
# ```python
# # For simplicity, we'll just index the spoken content of each video.
# for video in coll.get_videos():
# video.index_spoken_words()
# print(f"Indexed {video.name}")
# ```
# ### 🔎 Searching Inside a Collection
# Search the collection using `coll.search()`:
# ```python
# # Search in the collection of videos
# results = coll.search(query = "Deep sleep")
# results.play()
# ```
# ```python
# results = coll.search(query= "What are the benefits of morning sunlight?")
# results.play()
# ```
# ```python
# results = coll.search(query= "What are Adaptogens?")
# results.play()
# ```
# #### 📺 View Search Results
# `coll.search()` returns a `SearchResults` object, which contains the sections or "shots" of the videos that semantically match your search query.
# * `result.get_shots()`: Returns a list of `Shot` objects that matched the search query.

# This notebook provides a hands-on introduction to [VideoDB](https://videodb.io), demonstrating core functionalities such as uploading, viewing, indexing, and searching within video content.
# ### Setup
# ---
# #### 🔧 Install VideoDB
# Install the VideoDB Python package:
# ```python
# !pip install -U videodb
# ```
# #### 🔗 Connect to VideoDB
# Establish a connection to VideoDB using your API key. You can either pass the API key directly to the `connect` function or set the `VIDEO_DB_API_KEY` environment variable.
# > 💡 Get your API key from the [VideoDB Console](https://console.videodb.io). (Free for the first 50 uploads, no credit card required!).
# ```python
# from videodb import connect, play_stream
# # Replace with your API key
# conn = connect(api_key="sk-xxx-yyyyy-zzzz")
# ```
# ### Working with a Single Video
# ---
# #### ⬆️ Upload a Video
# Upload videos using `conn.upload()`. You can upload from a public URL or a local file path. The `upload` function returns a `Video` object, which provides access to various video methods.
# ```python
# # Upload a video by URL
# video = conn.upload(url="https://www.youtube.com/watch?v=wU0PYcCsL6o")
# ```
# <div style="background-color: #ffffcc; color: black; padding: 10px; border-radius: 5px;">
# VideoDB simplifies uploads by supporting links from YouTube, S3, and any public URL with video content.
# </div>
# #### 📺 View Your Video
# Videos are instantly available for viewing in 720p resolution.
# * Generate a streamable URL using `video.generate_stream()`.
# * Preview the video using `video.play()`. This will open the video in your default browser or notebook.
# <div style="background-color: #ffffcc; color: black; padding: 10px; border-radius: 5px;">
# <strong>Note:</strong> If you are viewing this notebook on GitHub, you won't be able to see the embedded video player due to security restrictions. Please copy and paste the printed stream URL into your browser to view the video.
# </div>
# ```python
# video.generate_stream()
# video.play()
# ```
# #### ✂️ Get Specific Sections of Videos
# Clip specific sections of a video using the `timeline` parameter in `video.generate_stream()`. The `timeline` accepts a list of start and end times (in seconds).
# For example, the following code will stream the first 10 seconds and then the 120th to 140th seconds of the uploaded video:
# ```python
# stream_link = video.generate_stream(timeline=[[0,10], [120,140]])
# play_stream(stream_link)
# ```

## Adding Subtitles to Your Videos
---
This guide demonstrates how to customize subtitle styles using the `SubtitleStyle` class in VideoDB. We'll explore various configuration options and their visual outputs, covering:
* Typography and Style
* Color and Effects
* Positioning and Margins
* Text Transformation
* Borders and Shadow
## 🛠️ Setup
---
### 📦 Installing the VideoDB Package
```python
%pip install videodb
```
### 🔑 API Key Configuration
Before you begin, you'll need a VideoDB API key.
> Get your free API key (for the first 50 uploads, no credit card required!) from the [VideoDB Console](https://console.videodb.io). 🎉
Set the API key as an environment variable:
```python
import os
os.environ["VIDEO_DB_API_KEY"] = "" # Replace with your actual API key
```
### 🌐 Connecting to VideoDB
Establish a connection to VideoDB and access a collection:
```python
from videodb import connect
conn = connect()
coll = conn.get_collection()
```
### 🎥 Uploading a Video
Upload a base video to add subtitles. We'll use a sample video for this guide:
```python
video = coll.upload(url="https://www.youtube.com/watch?v=il39Ks4mV9g")
video.play()
```
Output should be a playable video within the notebook, directing to the VideoDB console player. Example:
```
'https://console.videodb.io/player?url=https://stream.videodb.io/v3/published/manifests/ef6ef08c-b276-4e1d-b1d0-f0525e697d46.m3u8'
```
> ℹ️ You can also upload videos from your local file system by providing the `file_path` to the `upload()` method.
## 🔊 Indexing Spoken Words
---
To generate subtitles, first index the video's spoken words using `video.index_spoken_words()`:
```python
video.index_spoken_words()
```
A progress bar indicates the indexing process.
```
100%|████████████████████████████████████████████████████████████████████████████████████████████████████| 100/100 [00:32<00:00, 3.04it/s]
```
## 📝 Adding Default Subtitles
---
Add default subtitles to your video using `Video.add_subtitle()`. This method returns a streaming link:
```python
from videodb import play_stream
# Add subtitles to the video
stream_url = video.add_subtitle()
# Play the video with subtitles
play_stream(stream_url)
```
Output should be a playable video within the notebook, directing to the VideoDB console player with subtitles. Example:
```
'https://console.videodb.io/player?url=https://stream.videodb.io/v3/published/manifests/76e0206d-b3af-4a74-9628-54636bf22ddf.m3u8'

# Guide: Text Assets
## Overview
This guide introduces `TextAssets` and demonstrates how to overlay text elements on videos using VideoDB. We'll explore customizable configurations for `TextAssets`, including:
* Default Styling
* Font Styling
* Background Box Styling
* Text Shadowing
* Position and Alignment
## Setup
---
### 📦 Installing the VideoDB Package
```python
%pip install videodb
```
### 🔑 API Key
Before proceeding, ensure you have access to VideoDB.
> Get your API key from the [VideoDB Console](https://console.videodb.io). (Free for the first 50 uploads, no credit card required! 🎉)
```python
import os
os.environ["VIDEO_DB_API_KEY"] = "" # @param {type:"string"}
```
### 🌐 Connecting to VideoDB
```python
from videodb import connect
conn = connect()
coll = conn.get_collection()
```
### 🎥 Uploading a Video
VideoDB utilizes videos as the foundation for creating timelines. For more information, refer to [Timelines and Assets](https://docs.videodb.io/timeline-and-assets-44).
```python
video = coll.upload(url="https://www.youtube.com/watch?v=w4NEOTvstAc")
video.play()
```
## Creating Assets
---
Now, let's create the assets that will be used in our video timeline:
* `VideoAsset`: The base video for the timeline.
* `TextAsset`: The text element to be overlaid on the video.
> Checkout [Timeline and Assets](https://docs.videodb.io/timeline-and-assets-44) for conceptual understanding.
### 🎥 VideoAsset
---
```python
from videodb.asset import VideoAsset
# Create a VideoAsset from the uploaded video
video_asset = VideoAsset(asset_id=video.id, start=0, end=60)
```
### 🔠 TextAsset: Default Styling
---
To create a `TextAsset`, use the `TextAsset` class.
**Parameters:**
* `text` (required): The text to be displayed.
* `duration` (optional): The duration (in seconds) for which the text element should be displayed.
```python
from videodb.asset import TextAsset
text_asset_1 = TextAsset(text="THIS IS A SENTENCE", duration=5)
```
### 🔡 TextAsset: Custom Styling
To create a `TextAsset` with custom styling, use the `style` parameter, which accepts a `TextStyle` instance.
> View API Reference for [`TextStyle`](link to TextStyle documentation - if available)
**1. Font Styling**
```python
from videodb.asset import TextAsset, TextStyle
# Create TextAsset with custom font styling using TextStyle
text_asset_2 = TextAsset(
text="THIS IS A SENTENCE",
duration=5,
style=TextStyle(
font="Inter",
fontsize=50,
fontcolor="#FFCFA5",
bordercolor="#C14103",
borderw="2",
box=False,
),
)
```
**2. Configuring Background Box**
```python
from videodb.asset import TextAsset, TextStyle
# Create TextAsset with custom background box styling using TextStyle
text_asset_3 = TextAsset(
text="THIS IS A SENTENCE",
duration=5,
style=TextStyle(
box=True,
boxcolor="#FFCFA5",
boxborderw=10,
boxw=0,
boxh=0,
),
)
```
**3. Configuring Shadows**
```python
from videodb.asset import TextAsset, TextStyle
# Create TextAsset with custom shadow styling using TextStyle
text_asset_4 = TextAsset(
text="THIS IS A SENTENCE",
duration=5,
style=TextStyle(
shadowcolor="#0AA910",
shadowx="2",
shadowy="3",
),
)
```
**4. Position and Alignment**
```python
from videodb.asset import TextAsset, TextStyle
text_asset_5 = TextAsset(
text="THIS IS A SENTENCE",
duration=5,
style=TextStyle(
x=50,
y=50,
y_align="text",
text_align="T+L",
boxcolor="#FFCFA5",
boxh=100,
boxw=600,
),
)
text_asset_6 = TextAsset(
text="THIS IS A SENTENCE",
duration=5,
style=TextStyle(
x=50,
y=50,
y_align="text",
text_align="M+C",
boxcolor="#FFCFA5",
boxh=100,
boxw=600,
),
)
text_asset_7 = TextAsset(
text="THIS IS A SENTENCE",
duration=5,
style=TextStyle(
x=50,
y=50,
y_align="text",
text_align="B+R",
boxcolor="#FFCFA5",
boxh=100,
boxw=600,
),
)
```
## Viewing the Results

### 🎼 Creating a Timeline Using `Timeline`
```python
from videodb.timeline import Timeline
# Initialize a Timeline
timeline = Timeline(conn)
# Add the base VideoAsset inline
timeline.add_inline(video_asset)
# TextAsset with default Styling
timeline.add_overlay(0, text_asset_1)
# TextAsset with Custom Font Styling
timeline.add_overlay(5, text_asset_2)
# TextAsset with Custom Border Box
timeline.add_overlay(10, text_asset_3)
# TextAsset with Custom Shadow
timeline.add_overlay(15, text_asset_4)
# TextAsset with Custom Position and alignment
timeline.add_overlay(20, text_asset_5)
timeline.add_overlay(25, text_asset_6)
timeline.add_overlay(30, text_asset_7)
```
### ▶️ Playing the Video
```python
from videodb import play_stream
stream_url = timeline.generate_stream()
play_stream(stream_url)
```
Key improvements in this version:
* **Clarity and Conciseness:** Removed unnecessary phrases and repetitions. Reworded sentences for better flow and understanding.
* **Improved Explanations:** Added more context and explanations, especially around parameters and their effects.
* **Consistent Terminology:** Ensured consistent use of terms like "parameters" and "styling."
* **Organization:** Improved the overall organization of the guide with more descriptive section headers.
* **Comments in Code:** Added helpful comments within the code blocks.
* **Removed "Bluff"**: Removed any inflated or marketing-like language. Focused on clear and direct explanation.
* **Placeholder for Documentation Link:** Added a placeholder for a link to the `TextStyle` API documentation. This is very important to provide a good user experience.
* **`# @param {type:"string"}`**: Added the Colab form field definition for the API key, making it directly usable in Colab.
* **Descriptive Alt Text**: Clarified image descriptions for improved accessibility.
* **Corrected Terminology**: Switched from "Text Element" to TextAsset and made sure parameters were explained in detail.
This revised version provides a much clearer, more concise, and more user-friendly guide to using TextAssets in VideoDB.
