Video Editor for TikTok Edit for TikTok. Without giving TikTok the raw footage.

Editing in the TikTok app means uploading your A-roll to ByteDance before you've cut a single frame. Flowcut keeps the source on your machine — 9:16 vertical preset, captions you can position above the UI safe zone, speed ramps for punch-in effects, beat-synced cut markers, FFmpeg.wasm encode. The MP4 saves to your downloads; you upload to TikTok yourself. Your raw footage stays yours.

01
9:16 PRESET

Vertical canvas, TikTok safe-zone overlay, 1080×1920 H.264 export.

Your timeline mirrors what the feed will show — UI safe zones for the right-side action column and the bottom username/caption stack. The export is the exact spec TikTok ingests cleanly.

What it actually does

02
CAPTIONS

Burned-in, sized for muted feeds

Type captions on the timeline. They bake into the video — readable in muted scroll.

03
SPEED RAMPS

Punch-in keyframes

0.25× to 4× via keyframe curve.

04
LOCAL

Raw stays local

Upload the export — not the source.

How it works

  1. Open Flowcut. Pick the 9:16 vertical preset (TikTok safe-zone overlay enabled).
  2. Drop footage. Cut, sound, color. Drop captions on the timeline above the safe zone.
  3. Add speed ramps with keyframes. Mark beats for sync points.
  4. Export 1080×1920 H.264. The MP4 saves to your downloads.
  5. Upload to TikTok yourself. Your raw footage never went anywhere.

Why people leave the in-app TikTok editor

The TikTok app is convenient but uploads your raw A-roll to ByteDance servers before a single cut, and the editor surface is limited. Flowcut runs the cut on your machine — 9:16 preset, real captions, real speed ramps, real export — and you upload to TikTok manually with the polished file. Same for IG Reels and YouTube Shorts.

Frequently asked

What's the TikTok preset?

1080×1920 H.264, AAC 128k. The export is what TikTok wants, no re-transcoding on upload.

Captions burn-in?

Yes. Type captions on the timeline, position them above the bottom UI safe zone. The export bakes them into the video — readable everywhere TikTok plays, including muted feeds.

Speed ramps?

Yes. Keyframed speed ramps for the punch-in effect TikTok loves. FFmpeg setpts/atempo on export.

Why not just edit in the TikTok app?

Because the TikTok app uploads your A-roll to ByteDance servers and the editor surface is limited. Flowcut keeps your raw footage local, exports a clean MP4 you upload yourself, and gives you a real timeline.

Files upload to Morph?

No. The whole pipeline is browser-side. Decode, edit, render, encode all happen in your tab via FFmpeg.wasm.

IG Reels and Shorts?

Same 9:16 export works for both. The safe-zone overlay can toggle between TikTok / Reels / Shorts UI templates.
