A project → Upload Scenes.
Drop in as many video segments as you like, put them in the order you want, and stitch them into one
film. Useful when the footage already exists — shot on a camera, cut elsewhere, or generated
somewhere else and brought here to be finished.
### They become real scenes
Each segment creates a scene with one shot behind it. That is deliberate: from that moment the
timeline, captions, dubbing, the NLE export and publishing all work on it exactly as they would on a
generated shot, because they are all built on scenes.
A separate "uploaded clips" list would have been quicker to build and would understand none of that.
### Two different drags
Files are dragged in from your desktop, onto the drop zone. Scenes are dragged around within
the list to reorder them. Dropping a file onto a row does nothing — that gesture belongs to the zone
above, and the row ignores it rather than doing something surprising.
Uploads land in filename order, because that is how people number segments. Drag afterwards if it is
wrong.
### The start times are the point
Every row shows where it starts in the finished film, and the numbers update as you drag. "Scene 4"
tells you nothing about whether the cut lands at forty seconds or four minutes; the timecode does.
### Length, and why it is fussed over
Duration decides where every later clip starts. One wrong number and everything after it drifts —
which on screen looks like a rendering fault rather than a data problem.
So the length is labelled with where it came from:
- measured — the server measured it with ffprobe. Authoritative.
- browser-reported — your browser read it from the file. Normally exact.
- you set this — you typed it, correcting one of the others.
- assumed — nothing above was available, so ten seconds is a placeholder.
Stitching is blocked while any length is assumed. That is the one case where going ahead
produces a film that is quietly wrong everywhere after the bad segment. Type the real length into
the box on that row and the block lifts.
### Stitching
Stitch into one film lays every scene onto the picture track in order. It is the same assembly
the generated path uses, so a film that mixes uploaded and generated scenes assembles correctly with
no extra step.
Run it again after adding or reordering: it repoints and re-times rather than duplicating, so
re-stitching is safe and does not double your film.
### Removing
Removing an uploaded scene takes its timeline clip with it and closes the gap in the numbering. **The
file stays in your library** — delete it there if you want the space back.
Written scenes cannot be deleted from this screen. They hold dialogue, shot lists and camera work
that this view cannot show you, so they are removed from the Script where you can see what you are
losing.
### Limits
512MB per segment, and uploads count toward your
[storage quota](/help/storage-quotas) like anything else. MP4, MOV, WebM, MKV and MPEG.
