Playback, preview quality, and export
Loop modes for previewing the cut, preview quality for slower GPUs, and the same six export paths as a paper edit
Once the cut is matched, locked, and tuned, the last bit is reviewing it and getting it out. The transport, the preview quality menu, and the Export menu all live in the workspace header.
Loop modes
Tri-state in the transport bar:
- Off: plays once and stops
- All: loops the whole timeline
- One: loops just the focused splice
One is the mode you want when auditioning alternates. Click a different splice and the loop reseats around the new focus. Makes A/B-ing takes a tight little exercise.
Preview quality
Header has a Quality menu: Full, Half, Quarter. Lower quality means smoother live preview on slower GPUs. The menu is preview only. Export always renders at full quality regardless of what preview is set to.
Drop to Quarter on a busy timeline and you get fluid scrubbing back. Bump to Full when you're checking final framing.

Export
Same Export menu as Paper Edit. Six output paths:
- Final Cut Pro (FCPXML): the timeline lands in FCP as a new event prefixed
Mosaic -. - Premiere or Resolve (FCP7 XML): legacy xmeml file, with an optional
.srtsidecar. - Video: H.264 MP4, HEVC MP4, or ProRes 422 MOV.
- Image sequence: numbered PNG frames.
- Audio-only: AAC
.m4aor WAV. - JSON: the project as a portable file. Script, entries, corpus, settings, captions all in one doc.

A note on captions
Mosaic captions today export through the Captions Editor's own export menu, not through the Mosaic Export menu directly. So if you've written captions for this Mosaic, open the Captions Editor and use its export to get them out. We'll fold this into the Mosaic export menu later, but for v1, two doors.
What you don't get
One assemble produces one timeline at one resolution. No aspect-ratio variants, no multi-output short-form factory. If you need 16:9 and 9:16, that's two assembles today.
That's a deliberate scope call. We'd rather ship one cut that's right than five cuts that are all a bit off. Multi-output is on the list, just not in v1.
