Suila

Suila (水啦) is a video editor. Open it and start cutting — no sign-in, no ads, your videos never leave the phone.

What's in it:
• Auto captions (on device): speech to captions in Mandarin, Cantonese, English, Japanese and Korean; lines break by word and by breath. Edit by hand, drag them into place, add a second language for bilingual captions, import and export SRT.
• Caption styling: font, color, outline, shadow, size and position, with 63 Traditional Chinese, Japanese, Korean and Latin fonts downloaded on demand — or import your own .ttf/.otf.
• Beauty: finds faces automatically and retouches skin only — smoothing, dark circles, blemishes — features stay untouched.
• Automatic face mosaic: faces are tracked frame by frame and pixelated or blurred; tap once to keep the main subject.
• Voiceover and teleprompter: record narration straight into the phone with your script on screen.
• Multi-point speed curves: add control points for smooth slow motion and speed ramps; reverse and freeze frame too.
• Intuitive timeline: split, trim, long-press to reorder; deleting closes the gap, no black frames.
• Text and stickers: free placement, colors, outline, shadow, in/out animations; emoji and sticker packs.
• Filters, color and effects: cinematic LUTs, brightness/contrast/saturation/temperature, underwater correction, plus 15 visual effects.
• 19 transitions and keyframe animation.
• Picture-in-picture, extract audio from video, your own music and built-in sound effects, watermark, cover, end card.
• Six canvas ratios (9:16, 1:1, 16:9, 4:5, 3:4, 4:3), 4K export — what you preview is what you get.

Everything is free. If you like it, you can support the developer inside the app; supporting unlocks nothing.

Your videos, audio and projects stay on your device; no tracking, no personal data collected.

Cut it, and 水啦!
