Questions,
answered.
How ClipFast turns stream highlights into vertical videos —
and what happens to your files.
What is ClipFast?
ClipFast is a free online video editor that turns Twitch clips and stream highlights into vertical 9:16 videos for TikTok, YouTube Shorts and Instagram Reels. Trim footage, arrange gameplay and facecam, add captions and audio, then download your edit — all in your browser, approved beta account required.
How do I turn a Twitch clip into a TikTok or Short?
Upload a video file you own or have permission to edit, pick a vertical layout such as split screen or facecam overlay, trim to the best seconds, add captions if you like, then export. Download the MP4 and upload it to TikTok, Shorts or Reels yourself.
Is ClipFast free?
Yes. ClipFast is free to use and requires beta approval. Open the editor in your browser, cut your clip and export it.
Do my video files stay in my browser?
Manual editing and export run locally in your browser. Optional automatic transcription sends audio to the transcription service. The separate AI clipping workflow processes public Twitch VOD audio on a server and stores transcripts and selected preview clips.
Can AI find moments in a Twitch VOD?
The AI clipping MVP analyzes speech in a public, finished Twitch recording and suggests short moments to review. Prepare a preview, then open it with captions in the existing editor. Processing continues after you close the page while the recording processor remains running.
Can I keep my gameplay and facecam in the same vertical video?
Yes. Choose split screen, a round facecam, a small facecam overlay, or fullscreen. Then adjust the crop and facecam position so the action and your reaction both stay in frame.
Can I add captions and my own sound effects?
Yes. Add and style captions, adjust their timing, and place uploaded music or sound effects on the timeline. Automatic caption generation requires the transcription service to be configured.
What format will my video export in?
Export runs in your browser. MP4 is used when your browser supports it; otherwise the editor downloads WebM. Available formats depend on your browser.
Do I need to install a desktop editor?
No. The editor runs entirely in your browser. The optional free ClipFast Chrome extension adds a shortcut (Alt+C) for capturing the Twitch moment you are watching; you still edit an authorized source video in the editor.
Does ClipFast post directly to TikTok, Shorts or Reels?
No. ClipFast prepares the vertical video — you download the file and upload it to each platform yourself. That keeps your accounts and your footage under your control.
Which clips am I allowed to use?
Only video you own or have permission to edit, such as your own streams and highlights. Respect the platform rules and the rights of other creators before uploading anywhere.
