AI video tools: dub, cut out, extend, add sound and upscale a video
These workflows start from a video you already have and transform it: another language with lips in sync, the background removed without a green screen, the continuation of a shot, an ambient soundtrack, visual effects, or simply more sharpness.
Every page shows the starting shot and the result, as the demo produced them, with the model used and the real cost. These are editing tools: they keep your shot and do not invent another one.
What you can do here
- Dub a video into another language without reshooting
- Remove the background from a video shot without a green screen
- Extend a shot that is too short
- Add sound or effects to a silent shot
- Upscale a low-definition video to 1080p

Video dubbing
Another language, the same lips
A video where someone speaks, a new voice in another language: Sync Lipsync 3 re-times the lips to the new text. The same shot in English and in Spanish, without reshooting. The whole workflow is visible without an account.
Interactive demoVideo background removed
The subject alone, no green screen
A video shot on a phone, no green screen: Bria isolates the subject and removes the whole set, frame by frame. The same shot as a transparent webm and as an mp4 on a green background, sound kept. The whole workflow is visible without an account.
Interactive demoExtend a shot
The continuation, from the last frame
A five-second shot that stops too early: Grok Imagine generates the continuation from its last frame, in the same format, and the Montage node chains the two. Two possible continuations of the same shot. The whole workflow is visible without an account.
Interactive demoVideo VFX
Same shot, three effects
A plain shot edited three times by Seedance 2.5: an explosion behind, a storm, an energy sphere. The shot does not change, the effect is added. The full workflow is visible without an account.
Interactive demoSharpen a video
Two upscalers, two settings
A camcorder shot 480 pixels wide, enlarged to 1080p by both video upscalers side by side. The full workflow, no account needed.
Interactive demoAdd sound to a video
The silence that gives generated shots away
A silent shot, an ambience bed and a music bed: the three pieces are generated here, the montage assembles them. The full workflow, no account needed.
Interactive demoFrequently asked questions
Which video formats are accepted?
An mp4 or a mov, up to 150 MB, dropped on the canvas. The accepted length depends on the tool: a few seconds to extend a shot, up to several minutes to remove a background or sharpen.
Is the original video modified?
No. The imported file stays intact in the Media node; every result is a new file, downloadable separately.
