3. Export graded video

Save as MP4, WebM, or GIF (GIF encodes at fps=10 via palettegen; downloads are unlimited).

Frequently Asked Questions

How do I fix dull morning footage?

Raise brightness +10, contrast +15, saturation +10 as a starting recipe: flat 7am clips gain punch without clipping highlights. Preview on the brightest frame before exporting.

Which filter for a vintage look?

Lower saturation to −30, warm the tones, add slight contrast: instant film feel. Grayscale at full strength suits dramatic B-roll and title backgrounds.

Do filters slow down export?

Slightly — each filter adds a processing pass, roughly 20–30% longer than plain conversion. A 5-minute 1080p clip still finishes in a few minutes on a laptop.

Are my videos uploaded for filtering?

No — filtering runs locally in your browser with FFmpeg WASM. Only the final save touches the network — downloads are unlimited.
