Patch the latest MontageProposal already shown in the UI. Use only for an existing video montage/reel/stitched sequence proposal; do not use this to modify a photoshoot brief. For photoshoot brief changes, call update_brief instead. Prefer operations, an ordered list of typed montage edits such as clear_trim, remove, set_duration, set_trim_range, set_speed, set_muted, set_prompt, set_video_model, set_generate_audio, set_last_frame, set_aspect_ratio, and set_base_resolution. Use set_trim_range for requests like 'use the second half', 'start at 3s', or 'trim from 3s to 6s'. Operations are applied in order to the current montage state. Legacy flat fields are still accepted as a compatibility shim. This updates the proposal only; it does not execute export or generation.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| operations | array | no | Ordered montage patch operations. Preferred over the legacy flat fields below. |
| clip_number | integer | no | 1-based clip number to update. Omit when apply_to_all=true. |
| clip_numbers | array | no | Optional list of 1-based clip numbers to update together. |
| apply_to_all | boolean | no | Apply changes to every clip in the current montage proposal. |
| remove | boolean | no | Remove the selected clip(s) from the proposal. |
| clear_trim | boolean | no | For video clips, remove trim bounds and restore the full clip length in the proposal. |
| target_duration | number | no | Desired final clip length in seconds. |
| start_time | number | no | Trim start time in seconds for legacy trim-range updates. |
| end_time | number | no | Trim end time in seconds for legacy trim-range updates. |
| speed | number | no | Playback speed multiplier. |
| muted | boolean | no | Mute or unmute the selected clip(s). |
| prompt | string | no | Update the motion prompt for image-to-video montage items. |
| video_model | string | no | Update the video model for image-to-video montage items. |
| generate_audio | boolean | no | Enable or disable generated audio for image-to-video montage items. |
| last_frame_url | string | no | Optional last-frame URL for image-to-video montage items. |
| aspect_ratio | string | no | Update the montage output aspect ratio. |
| base_resolution | integer | no | Update the montage output resolution height. |
