Pr Tracks & Clips

• Apply Audio Effect: Adds an audio effect to a track item.
• Apply Transition: Adds a transition at the Track Item's IN, OUT or BOTH edges.
• Apply Video Effect: Adds a video effect to a track item.
• Clear Component Param Keyframes: Deletes keyframes from a component parameter.
• Delete Component Param Keyframe: The supplied timeSeconds uses the same nearest-tick conversion as keyframe creation, including the existing unsafe-integer seconds fallback and warning.
• Fill Track With Items: Fills a track range with one or many items according to fill strategy settings.
• For Each Track: Iterates tracks of a sequence (filtered by kind and order).
• For Each Track Item: Iterates over the items of a track, with optional kind filter, time range, and order.
• Get Clip Ref: Returns a clip reference from a track, resolved by index or name.
• Get Component Param Interpolation At Time: The pointer lookup uses the nearest tick so it can address keyframes created or interpolated by the normalized write paths, even when supplied a computed time just below the intended boundary.
• Get Component Param Property: Reads the property selected in property from a component parameter.
• Get Component Param Ref: Returns a component-parameter reference, resolved by index or name.
• Get Component Param Value At Time: Returns the value of a component parameter at timeSeconds.
• Get Component Property: Reads the property selected in property from a component.
• Get Component Ref: Returns a component reference from a track item, resolved by index or name.
• Get Item Ref: Returns one item reference from a track.
• Get Track Item Property: Reads the property selected in property from a track item.
• Get Track Property: Reads the property selected in property from a track.
• Get Track Ref: Resolves a track by index or name.
• Insert Mogrt From Library: Inserts a Motion Graphics Template from an Adobe Library into a sequence.
• Insert Mogrt From Path: Inserts a local Motion Graphics Template into a sequence.
• List Audio Effects: Returns the names of audio effects available in Premiere.
• List Component Param Keyframes: Returns the keyframes of a component parameter as a list.
• List Component Params: Returns the parameters of a component as a list.
• List Components: Returns the components attached to a track item as a list.
• List Selected Track Items: Reads the current timeline selection from the supplied sequence; when sequence is omitted, it uses the active sequence.
• List Track Items: Returns the items on a track as a list.
• List Tracks: Returns the tracks of a sequence as a list.
• List Video Effects: Returns the names of video effects available in Premiere.
• List Video Transitions: Returns the names of video transitions available in Premiere.
• Place Item In Sequence: Preferred single-item timeline placement block for insert and overwrite workflows.
• Scene Edit Detect: Runs Premiere's Scene Edit Detection on one video clip item or a list of video clip items.
• Sequence Remove Items: items is the explicit mixed Track Item selection to remove.
• Set Component Param Interpolation At Time: Both the preflight keyframe pointer and the queued interpolation Action receive the same nearest-tick TickTime.
• Set Component Param Keyframes: The existing-key Undo limitation is also confirmed for one clearMode=NONE bulk write on macOS Premiere 26.5.2 Motion/Scale: replacing the original LINEAR key with value150/HOLD produced the expected exact-tick key, but one physical Undo removed the original key.
• Set Component Param Value: Sets the current value of a component parameter.
• Set Component Param Value At Time: Known native Undo limitation: on macOS Premiere 26.5.2, updating an existing Motion/Scale LINEAR key through the native Add action changed its value correctly, but one physical Undo removed the original key instead of restoring it.
• Set Track Item Property: Writes the selected property on a track item.
• Set Track Item Selection: Changes the selected timeline clips in the supplied sequence; when sequence is omitted, it uses the active sequence.
• Set Track Property: Setting IS_MUTED calls Premiere's Track setter immediately.
• Track Item Clone: Duplicates a Track Item with a time offset and destination-track offsets, using an Insert or Overwrite edit.
• Track Item Move: startSeconds is an absolute time in sequence coordinates, not a relative delta.
• Track Item Slip: offsetSeconds is a relative offset in source-media time.
• Track Item Trim: This is a low-level advanced edit primitive over Premiere's coupled start/end/source-in/source-out actions.
