dramapack

dramapack turns short-drama episodes (vertical dramas, micro dramas, AI dramas) into a platform-ready delivery package — TikTok Drama Center / DramaWave / ReelShort submission pack, -14 LUFS mastering, burned subtitles inside the subtitle safe area, clean masters, 3:4 covers, local QC (black frames, subtitle/speech alignment, optional bring-your-own vision-model checks) and music/font rights check — from the command line or as an MCP server for AI agents.

Why

Between "the episode is rendered" and "the platform accepted it", the same things go wrong for every short-drama studio:

• Submission packs: numbered episodes, same-name SRTs, 3:4 covers, a clean master, edit evidence, chain of title, AI disclosure. Dozens of manual steps per series. → delivery package guide

• Phone-speaker loudness: raw AI renders sit at -20 to -27 LUFS; the feed around them is near -14. And ffmpeg loudnorm silently goes dynamic on dialogue and lifts the noise floor by 30-50 dB. → -14 LUFS guide

• Subtitle safe areas: ffmpeg's default 384x288 ASS canvas scales every size ~6.7x; fixed margins land under the player bar or exceed TikTok Drama Center's 70%-width rule. → safe-area guide

• Clean masters that are really the same edit as the subtitled one. → clean master guide

• Rights hygiene: no major-label music, commercial-free fonts only. → rights checklist

• TikTok Drama Center rejections: a dark band along one edge (black bars, code 4) and frame 0 as the default episode cover. --target tiktok-dc lifts the edges and opens every episode on a 1 s cover still. → Drama Center section

• QC before upload: black frames mid-episode, dark edge bands, subtitles that drift from the speech, speech nobody subtitled, likely subtitle typos; optionally AI visual defects (hands, faces, identity drift, garbled text) and content-policy flags with your own vision model or a local one. Free, local, no account; no network calls unless you opt in. Lip-sync is not covered. → local QC guide

Install

Requires Python >= 3.10 and ffmpeg (with libass + libx264) on PATH. For CJK subtitles install Noto CJK fonts (apt install fonts-noto-cjk).

pip install dramapack
# or run without installing:
uvx dramapack --help

Optional dialogue-density metrics and subtitle/speech alignment: pip install "dramapack[speech]".

60-second quickstart

# input/ holds 01.mp4 02.mp4 ... (un-subtitled cuts) and 01.srt 02.srt ...
dramapack check-rights --input input/          # music + fonts: fix red first
dramapack package input/ out/ --title "My Show" --studio "My Studio" --bed tension
dramapack audit out/episodes/01.mp4 --cut input/01.mp4   # QC: black, subtitles, pacing
dramapack inspect out/episodes/01.mp4          # LUFS, true peak, specs

out/ now holds episodes/ (subtitled, -14 LUFS) with same-name .srt, clean/ (no subtitles, same edit), covers/ (3:4), timeline/, docs/ (chain of title to sign, AI disclosure), manifest.json and a README for the recipient. Add --platform-pairs for two-episodes-per-file cuts. Optional show.json / rights.json / covers / timelines: see examples/input/ and the reference.

For AI agents

claude mcp add dramapack -- dramapack mcp

MCP tools: inspect, master, package, audit, check_rights. Each returns JSON with ok and a green/yellow/red status. Every CLI subcommand also takes --json; exit codes are stable (0 ok, 1 red, 2 usage, 3 failure). The repo doubles as a Claude Code plugin (.claude-plugin/, skills/dramapack/) and has an MCP Registry entry (server.json). → agent guide · AGENTS.md · llms.txt
