API 1.7.0: cutting, music, voice, captions from speech
Editing through the API and MCP covers everything the timeline does: cuts, freeze frames, music, voice, inserts. New: captions from speech at cost.
The single edit operation catalog has grown — the new operations work in POST /v1/projects/{id}/edits, in the MCP tool
edit_project, in the AI assistant and for the director in the Chat. All of them are free.
Cutting and fragment look
split_block,trim_block,duplicate_block— split a fragment at a video moment, trim or extend it at the start or end, duplicate it.freeze_frameandset_hold— a freeze frame and its length.replace_source— show another source in a fragment; in a fragment with speech the new picture goes over it as an insert.set_process— free processing: reverse, stabilization, noise reduction, audio enhancement.apply_keyframe_preset— a camera move across the whole fragment: zoom in, zoom out, pan.tune_block— the newbackgroundfield: a blurred background or a colour behind a fitted picture.
Music and voice
set_music,remove_music— a track from the sources or project media, volume, ducking under speech, start, fade-in and fade-out.fit_music,fit_to_beats— the track fitted to the video length, footage cuts snapped to the beats.add_voice,move_voice,trim_voice,set_voice_volume,remove_voice— a voice recording on the voice track.
Inserts and elements
add_insert,update_insert,remove_insert— your own photos and videos over the video, full frame or in a window.update_plaque,update_card,update_zoom— change a plaque, a card (label, your own photo) and a zoom in place.set_element_position— move an emoji, card or plaque around the frame.set_phrase_text,reset_phrase_text— the caption text of a whole phrase.move_element— now also moves sounds and markers.
Captions from speech
POST /v1/projects/{id}/transcribe— recognise the speech in the sources, like Captions from speech in the editor: after that a project without the AI director gets captions, and words withids appear in the video text. Thesourcesandlanguagefields are optional. Priced at cost per minute of sound: withoutconfirmCostthe response is the price (aQuotewithestimateandcost), with it — a start in the background.GET /v1/projects/{id}/transcribe— recognition jobs: processing, ready or failed (then the tokens come back).POST /v1/estimate— the newtranscribekind (needsprojectId).- MCP — the
transcribe_speechandget_transcribe_jobstools.
New skip reasons: block_or_source_not_found, audio_not_found, no_music_or_beats, recording_not_found,
media_or_place_not_found, word_not_found. Clients don't need to change anything — all changes are within /v1.
