List all sequences with size, frame rate, duration and track counts

Overview of the sequence open in the timeline: settings, playhead, in/out, every track (clips, muted, locked, targeted)

Open a sequence in the timeline

Create a sequence and open it. Defaults to 1920x1080 25 fps; set width/height/fps for other formats (e.g. 1080x1920 for vertical).

Create a sequence matching the clips' settings, with the clips placed in order

Duplicate a sequence

Rename a sequence

Delete a sequence from the project

Close a sequence's timeline tab

Frame size, fps, pixel aspect, audio and render settings of the active sequence

Change frame size, frame rate or render quality of the active sequence

Detect cuts inside the selected clips (select them first with select_clips) and cut them, add markers or make subclips

Make a new sequence from the active sequence's in/out range

List clips in the active sequence with timeline start/end, duration, source in/out (seconds), speed and state. Clip indexes change after edits, so re-read after cutting or moving.

Full details of one clip: timing, linked clips, applied effects

Find timeline clips whose name contains text

Clips under a given time on every track

Insert edit: place media at a time and push everything after it later

Overwrite edit: place media at a time, replacing whatever is there

Place media right after the last clip on a track

Delete a clip (and its linked audio/video by default). ripple=true closes the gap.

Move a clip (with its linked clips) to a new start time on the same track

Move a clip to another track of the same type, keeping its time

Trim a clip's edges on the timeline: newStart trims/extends the head, newEnd the tail (source media follows). Linked clips are trimmed too. Leaves gaps; use close_gaps or ripple_delete_range to close them.

Cut the clip on one track at a time

Cut every unlocked track at a time (like Add Edit to All Tracks)

Remove a time range from every unlocked track and close the gap (great for cutting out mistakes, silences or a section)

Remove empty space between clips by sliding clips left

Change clip speed (1 = normal, 2 = 200%, 0.5 = 50%). Linked audio follows. With ripple, later clips move to make room / close up.

Enable or disable a clip

Rename a clip instance on the timeline

Link clips together (e.g. a video clip and an audio clip)

Unlink a clip from its linked audio/video

Slip: show a different part of the source without moving or resizing the clip (positive = later in the source)

Slide: move a clip left/right while its neighbours are trimmed to compensate

Clips selected in the timeline

Select clips in the timeline

Clear the timeline selection

Names of available effects or transitions (use a filter, the full lists are long)

Add an effect to a clip (video effect on video clips, audio effect on audio clips)

Remove an added effect from a clip

Every effect on a clip (incl. Motion, Opacity, Volume) with property names, values and keyframes

Read one effect property

Set an effect property. If the property is animated (or time is given) a keyframe is set instead.

Add/update a keyframe. Time is the sequence time in seconds (must be inside the clip).

Keyframes of a property (times in sequence seconds)

Delete one keyframe

Remove all keyframes from a property (turns animation off)

Set keyframe interpolation (linear, hold, bezier/ease) for one keyframe or all

Motion/Opacity of a video clip in pixels: x, y, scale, rotation, anchor, crop, opacity

Position/scale/rotate/crop/fade a video clip. x,y are pixels of the frame center point (frame center = width/2, height/2). Give time to keyframe the change (e.g. for a zoom or move).

Transitions on the active sequence's tracks

Add a transition at a clip's start, end or both (default Cross Dissolve / Constant Power, 1 s, centered on the cut). Length is limited by available handles.

Remove a transition (index from get_transitions for that track)

Add a marker to the active sequence

Add many sequence markers at once (e.g. chapters or beat markers)

All markers on the active sequence

Change a sequence marker

Delete a sequence marker

Delete all markers on the active sequence

Markers on a project item's media

Volume of an audio clip in dB (plus keyframes and L/R channel levels if present)

Set an audio clip's volume in dB (0 = unchanged, -6 = half as loud, +6 louder; max +15). Give time to set a keyframe instead.

Fade an audio clip in and/or out with volume keyframes

Left/right channel levels (dB) of a stereo clip, e.g. to balance or pan it

Audio Track Mixer fader level of a track (dB)

Set the Audio Track Mixer fader of a track (dB, max +6)

Mute (disable) or unmute an audio clip

Export presets installed with Premiere / Media Encoder (and your own). Filter by name or format, e.g. 'youtube', 'h.264', 'prores', 'wav', 'png'.

Render the active (or named) sequence to a file inside Premiere and wait until it is done. Default preset: H.264 Match Source - High bitrate.

Send the sequence to Adobe Media Encoder's queue (renders in the background while you keep editing)

Render one frame of the active sequence (with all effects) and show it, so you can check how the edit looks. Also saved as PNG.

Export only the sequence audio (WAV 48 kHz 16-bit by default, or another audio preset)

Export the active sequence as Final Cut Pro XML

Export the active sequence as AAF (for Avid / Pro Tools)

Export the active sequence audio as OMF

Save the active sequence (and its media references) as a separate .prproj

Render timeline previews (in to out, or 'all')

Project panel metadata columns of an item (codec, duration, description, log note...)

Write a Project panel column: Description, Comment, Log Note, Scene, Shot, Good

Raw XMP metadata of a project item

Replace the XMP metadata of a project item (pass a full XMP packet, e.g. edited from get_xmp_metadata)

Create a caption (subtitle) track on the active sequence from timed text. These are real Premiere captions: editable and stylable in the Text panel, exportable as SRT, burnable on export. Right-to-left text works.

Create a caption track from an existing caption file (.srt, .scc, .mcc, .xml, .stl)

Burned-in styled captions as graphics clips (TikTok/Reels style): each cue becomes a text image on the timeline. Use add_captions instead when you want editable Premiere captions.

Add a text title to the timeline (rendered with the system text engine: any installed font, right-to-left scripts supported). Placed on a free video track above V1 unless trackIndex is given. To change it later, remove the clip and add it again.

Motion Graphics templates (.mogrt) installed with Premiere and in your Essential Graphics library

Place a Motion Graphics template on a video track. Returns its editable properties.

Motion Graphics templates stored in your Creative Cloud Libraries

Place a graphic from a Creative Cloud Library on a video track, optionally setting its text/values right away

The replaceable media slots (Media Replacement) of an After Effects .mogrt, a library graphic, or a template clip on the timeline (trackIndex + clipIndex), and the images behind them

Place an After Effects .mogrt / library graphic with your own images in its Media Replacement slots (and set its text). Builds a copy of the template with the images inside, so it renders like a normal template. Slots that share one image in the template change together.

Replace the image in a Media Replacement slot of a template clip that is already on the timeline. The clip stays in place with its text, settings, effects and keyframes. If other clips use the same template, by default only this clip changes (it is swapped for an identical copy with its settings carried over); scope 'all' changes every clip of that template in place instead.

Editable properties (text, colors, sliders, checkboxes) of a Motion Graphics template clip

Change a Motion Graphics template property: text (string), color ('#rrggbb'), number or boolean

Move the playhead

Current playhead time (seconds)

Redo undone action(s)

Run raw ExtendScript in Premiere Pro for anything the other tools don't cover. The value of the last expression is returned (objects are JSON-encoded). app, qe (after app.enableQE()) and the helper functions of this bridge are available. Times in the DOM are Time objects/ticks (254016000000 per second).
