Only remake what changed

You make a video of six clips. Five are right. The fourth shows a heron where you wanted a duck. What do you remake?

Only the fourth#

On the AI Vids timeline you change the words of clip four and press make. A clip that changed is remade; the clips that did not are kept. The video is stitched again from the clips, and you are charged for the one clip that was made again.

What counts as a change#

A clip's words, its length, the picture it starts or ends on, or making it a cut. Reordering or duplicating clips changes the timeline. A remake with a new seed asks for another take of the same clip.

The chain consequence#

Because each clip starts on the last frame of the one before, changing a clip changes where the next one would start. The next make makes every clip that is not in step, in order, so the chain stays continuous. That is the honest cost of a chain: a change in the middle can ripple on, and the composer shows the cost before you press.

How to use that#

Make a rough chain with short clips and the cheapest model first. Settle the order and the words. Then remake the clips that matter with a better model. And put cuts where you do not want the next clip to depend on the last frame, so that a change stays local.

Credits#

The composer shows the cost before you press make, including the clips that must be remade. A browser clip is charged when it is finished, and a server clip when the server made it, once per take.

What it does not do#

It does not decide which clip is wrong. You do. It keeps what you did not touch.

A small example#

Imagine a twelve-clip chain where you only dislike clip nine. If the chain after it is built on its last frame, clips ten to twelve may need remaking too. If you had put a cut before clip ten, they would not. Planning cuts where the scene changes is the cheapest way to keep a change local.
