AI VFX Video Generator
For VFX work, Manifold Video is the control pick: ordered keyframes and an exact stop frame give compositors predictable in and out points from ~101 credits (~$1.01). Seedance 2 handles complex simulation-like motion such as fire, smoke, and water at ~$1.67 per 5s with 1080p output.
For: Compositors, indie filmmakers, and previz artists generating FX plates, backgrounds, and set extensions.
Break the effect into layers
Split hero element, environment, and atmospheric passes. Generate each separately so you can comp them with real control.
Pin timing with keyframes
In Manifold Video, set the exact start and stop frames so the element enters and exits where your edit demands.
Generate simulation passes
Fire, debris, and water read best on Seedance 2 at 1080p. Generate multiple takes and choose the one whose physics read cleanest.
Integrate and mix
Track, key, and grade plates into your scene. Reuse generated audio beds or add SFX at ~$0.86 per 5 seconds for impact hits.
