Wan 2.1 VACE 14B
Edit a clip you already have: restyle it, change what is in it, keep its motion ("the same dance, but the dancer is made of glass"). One model, Apache 2.0, on a Linux GPU server — the first thing here that edits video at all.
What it costs
Free — downloads once, then runs on your own Mac with no per-image cost.
Where it runs
Downloads once and runs on your own Mac — no key, no account, no per-image cost.
