Frequently asked questions
Are my videos uploaded to GenVideoKit?
No. Processing runs in your browser. The FFmpeg WebAssembly engine is loaded in the browser and the selected source files remain on your device.
Why can some clips fail to merge?
Direct merging works best when clips use compatible codecs, dimensions, frame rates and audio layouts. Clips from the same AI generator are usually the easiest case.
Is this useful for AI video workflows?
Yes. AI video generators often render separate short shots. Merging lets you assemble those shots before a larger editing pass.
