AI video models make clips of a few seconds. Writers who cut them together describe the same two seams: the first frame of the next clip does not match the last frame of the one before, and the background sound breaks at every cut.

The problem

Regenerating until the frames happen to match costs credits each time. The sound seam is worse: each clip carries its own ambience, so the room changes every few seconds.

How Scenaloom handles it

  1. When a shot's clip is finished, the next shot offers Start from the end of shot N. The last frame is taken from the clip for free; the new clip is priced as usual.
  2. On export, Smooth the sound between clips of a scene lays a bed of room tone under the scene, taken from the quietest moment of its own clips, and dips each join.
Left: the last frame of clip 1. Right: the first frame of clip 2, made from it: same face, coat, deck and light
The last frame and the first frame of the next clip. Real outputs.
The second clip starts from the last frame of the first. Real outputs, joined without editing.

The result

A cut that holds the picture, and a room that keeps its sound. Room tone is laid in your browser when you export, and the clips stay yours to trim on the timeline.

Room tone needs two or more clips from the same scene. It smooths ambience at the joins; it does not replace a sound mix.

Questions

Does taking the last frame cost anything?

No. The frame is free; the next clip is priced as any clip is.

Can I turn room tone off?

Yes. It is an export option, on by default.
