Suila — Video Editor

Suila is a completely free video editor for iPhone and iPad. No accounts, no ads, no tracking, no personal data collected. Suila doesn't upload your videos, audio, or projects anywhere on its own — everything stays on your device. Its signature is multi-point speed curves — bend time with a single curve for slow motion and dynamic speed changes. Cut, caption, and score your video in minutes. Why you'll love it: • Multi-point speed curves (signature): add control points for smooth, dynamic speed changes and slow motion. • An intuitive timeline: split, trim both ways, long-press a clip to drag it into a new order; deleting closes the gap automatically — no black frames left behind. • Auto captions (on-device): turn speech into captions in dozens of languages, depending on your device — Traditional Chinese, English, Japanese, Korean, Spanish, German, and more. Generate from the main video or a picture-in-picture clip; adjust length and density; edit, split, and merge by hand — and drag them anywhere on the preview. • Auto face mosaic: detect and track faces frame by frame to mosaic or blur them; tap to keep your star unmasked, even in a crowd. • Fonts, your way: 5 built-in commercial-use CJK typefaces (including the handwritten ChenYuluoyan), or import any .ttf/.otf of your own. • Filters & color: cinematic LUTs plus brightness, contrast, saturation, temperature, and tint — plus one-tap underwater correction that brings back the red the water swallows. • Text & stickers: free positioning, fonts, colors, letter & line spacing, in/out animations, and emoji. • Transitions & keyframes: 19 transitions — dissolve, fade, push, slide, and zoom, plus whip pan, glitch, swirl, and more; animate position, scale, and opacity. • Picture-in-Picture: layer a second video — or a photo — over your main clip, with its own audio; captions generated from it move along with it. • Audio from video: extract any clip's soundtrack as an editable track; add music and royalty-free sound effects. • Watermark: put your name or brand — text or a logo image — on your video; position, size, and opacity are yours, shown the whole way through. • Canvas & end card: 9:16 / 1:1 / 16:9, plus an optional "Made with Suila" end card (free, toggle off anytime). • 4K export: preview is export — what you see is what you get. Cut it. Nail it.
