Video Postproduction
Choose deterministic clip assembly or an AI-directed HyperFrames composition.
Distinguish Quick Edit from AI Creative Edit
Video Edit starts in Quick Edit, where a structured edit plan drives a server-side FFmpeg render. Switching its mode to AI Creative Edit changes the node to a Motion/HyperFrames workflow.
- Right-click empty canvas, choose Video → Video Edit and place the node; connect two completed Video nodes.
- Use Quick Edit for fixed trims and audio levels; choose AI Creative Edit only when the task calls for a creative motion composition.
Set source-relative trim points
In Quick Edit, Sequence renders clips from top to bottom. Source in and Source out are seconds within each original clip, not positions on the final timeline.
- Use the up/down controls to order @1 before @2; set an in/out range within each displayed source duration.
- If a range turns red, use “Use full source” for that clip or shorten the out point before running.
Mix audio and time subtitles
Video and Audio sources are numbered separately. Quick Edit can retain or mute original audio, set clip volume, loop background music, and burn subtitles into the final output.
- Connect one Audio result, enable Background music, select its audio @ number and lower Music volume under spoken dialogue.
- Add subtitles with start/end times measured on the assembled video; play the render to verify text does not overlap the wrong sentence.
Use Advanced JSON only when necessary
The visual composer stores its choices as editPlan JSON: clips, source numbers, optional backgroundAudio, subtitles, and output settings. Malformed JSON is not a shortcut to a successful render.
- Use the visual controls for order, trims, fit, speed, ratio, and frame rate; open Advanced JSON only to inspect or carefully adjust the plan.
- If parsing fails, reset to connected-source order, then reapply only the edits you need; do not put provider API keys in the plan.
Hand off to Motion/HyperFrames
AI Creative Edit uses connected media to construct and render a HyperFrames project through a Codex-guided Motion path. It is distinct from both deterministic FFmpeg sequencing and the Runway Gen-3 video-restyling preset.
- Switch the Video Edit mode to AI Creative Edit and write a bounded instruction such as “Place title over the opening product shot; end with a clean logo hold.”
- Review the rendered frames and output; if you just need a trim or subtitle correction, switch back to Quick Edit instead of regenerating a creative composition.
