Captions, cuts and music: finishing AI video in Cinema Studio

What is on the timeline

• Video track: renders from your library and uploads from your device, up to 200 MB each.
• Audio tracks: generated music, voiceover and sound effects, or uploads, with per-clip fades.
• Titles track: captions and titles with drag positioning on the preview.
• Projects save in the browser and can be parked and reopened.

Trimming and stitching

Drag the edges of a clip to trim, drag clips to reorder, and the preview follows the frame you are cutting. For joins between AI renders, a short crossfade of about a third of a second hides most seams; for a continued shot, a hard cut is cleaner. Scene changes preview without a black gap.

Captions that read on a phone

Six treatments: classic, neon, box, outline, mono and script, with six accent colours and sizes from extra small to large that scale with the frame. On 9:16 the default anchor sits at 80 percent height so the bottom fifth, which platform UI covers, stays clear. What you see in the preview is what the export renders.

Music and voice

Generate a music track to the exact length of your cut, 14 credits, and lay it under all clips instead of keeping three different native soundtracks. Add a voiceover from text in any of the voice tiers. Scene Audio can compose dialogue, effects and ambience timed to the second.

Export

Export renders at the source resolution with a poster frame and lands in your library as a Cinema Studio export. Share it to the community feed or download it. An export is 25 credits for the first minute and 10 credits for each further minute, whatever the resolution; it is our compute, with no engine cost behind it.
