Center the subject

Beta · finds the main subject in each clip and keeps them centered when the export shape differs from the source. Best with one clear character. Falls back to a standard center crop. Adds a few seconds to export.

More options · quality, SFX

Upscale quality

Desktop: new sessions default to 4K export (heavy denoise, lanczos scale, sharpen, color pass). Pick 1080p for smaller files. Off trims preview styling, downloads still use full 4K-style cloud processing on desktop so the file stays sharp.

Sound effects on cuts Experimental

We scan your clips (motion + color) and pick from 70+ transition sounds, no repeats on every cut.

SFX volume 72%

Use these sounds

Whoosh Hit Swipe Riser Glitch Soft

Kick Snare Hi-hat

Transform mode, replace every beat with SFX

Keeps the kick pulse and the vocals, every other hit gets replaced with your SFX and the music ducks hard underneath.

SFX feedback Experimental

Hits sound robotic? Whoosh too high? Tell us what to fix, we read every reply.

Sharpen preview (Anime4K-style) Real-time WebGL upscale on the player. Works on both orientations. Off by default, toggle anytime. Heavier on the GPU.
