Make Twitch clips
vertical.

Route 1: Twitch's own portrait clips

1. Create the clip as usual (the clip icon on the player, up to 60 seconds).
2. Open it in Clips Manager: Creator Dashboard, Content, Clips.
3. Use Edit Layout to pick the ratio and arrangement. Twitch's auto crop detects your face cam and gameplay; there is a blur fill for the gaps. This is desktop-only for now.
4. Download the portrait version, or as channel owner post it straight to TikTok or YouTube Shorts.

This is a big improvement over the old workflow. What it leaves out: captions, unless you add them elsewhere, and it is one clip at a time, done after the stream.

Route 2: fix the crop in an editor

Download the landscape MP4 and open it in a vertical editor. CapCut and StreamLadder's free basic editor both handle the 9:16 crop, a cam-over-gameplay stack and captions. Expect ten to twenty minutes per clip if you want the captions right. It is the route for the one clip you care about a lot.

Route 3: automatic, while you stream

The third route is to never do it by hand. ReelShift watches your live Twitch stream, cuts moments as they happen, and every clip comes out already vertical: auto reframe tracks the action and keeps you centered, face-cam, gameplay or both, and word-synced captions are burned in. Say "clip that" to grab the last 60 seconds. The clips land in your library while you are live, export-ready for TikTok, YouTube Shorts and Instagram Reels. The clip editor is there if you want to nudge a crop, but most clips do not need it.

Vertical tips that apply to all three

• Cam on top, gameplay below is the layout viewers expect for gaming clips. Full cam for Just Chatting.
• Captions are not optional. Most short-form viewing is on mute; a clip without captions is a clip without dialogue.
• Keep your face cam in a consistent spot on stream. Every auto-crop tool, Twitch's included, works better when the cam does not move.
• Leave headroom. Overlays parked at the top or bottom of the 16:9 frame get cropped.
