Tutorial · Beginner

Your first vertical edit in the browser

Six steps, one take, no signup. The recording below is the whole tutorial performed on the production build — and the MP4 is the file that session's export actually produced.

1

Open the editor, bring one clip

No signup. Drag any MP4/MOV/WebM from your device into the Assets panel — it lands on V1 at the playhead and the timeline stretches to fit it.

2

Park the playhead on the first cut point

Click the timeline ruler or drag the red playhead. The transport bar under the preview steps ±1 second; Space toggles playback.

3

Split (S) and delete (⌫)

With the clip selected, S splits every track at the playhead; Delete removes the selected piece. Keyboard-first: the toolbar buttons mirror both.

4

Tidy the rhythm with Auto-Adjust

Gaps from your deletions collapse leftward in one click, per track or across all tracks, keeping each track's order.

5

Add a caption line

The Text button drops an editable text clip on T1 at the playhead — drag it anywhere on the canvas, restyle it, resize it. For spoken words, use AI Tools → Captions (local Whisper).

6

Export, watermark-free

Pick resolution (720p–4K) and frame rate (30/60), hit Render, keep the tab visible. The file downloads when the real-time render completes; save the project backup beside it.

First-hand captures

Recorded from the production build of this site: a real browser session driving the real editor, with no cuts or retakes. Output files below were produced by the editor's own export engine.

Unedited capture of the production build: text tool, canvas drag, export pipeline with live render progress, project backup. If a step above doesn't match what you see, trust the recording and tell us.

The genuine export from that session — 720 × 1280 H.264 at 30 fps. Download it and inspect the frames.

Supported formats

  • Import: MP4, MOV, WebM video; MP3, WAV audio; PNG, JPG, WebP, GIF images — read locally, never uploaded
  • Export: MP4 (H.264/AAC) where the browser supports recording (Chrome 126+, Edge, Safari); WebM (VP9/VP8) elsewhere; 720p–4K, 30/60 fps
  • Project files: .json backups covering clips, media references, timing and settings

Known limitations

  • The browser render is real-time: a one-minute edit takes about one minute to export, and the tab must stay in the foreground
  • Undo/redo history is capped at recent changes — save a project backup before big experimental passes
  • Large projects live in browser storage, which is finite; heavy footage belongs in project-file backups
  • Effects, keyframes and transitions are early beta — check the changelog before planning around them

Next: text, layering and safe zones, or the full stream-to-shorts workflow.
