Reframing to vertical means picking which part of the wide frame survives the crop. In Vyra a rectangle mask is the crop. You say what to keep centered, and the speaker stays in frame while a screen recording crops to the part you're pointing at.

How it works

  1. Upload the horizontal video. Set the canvas to 9:16, or ask the chat to.
  2. Say what should stay in frame. The speaker, a product, a region of the screen.
  3. The agent applies masks per section so the crop follows the subject.
  4. Add captions in the safe area and check a few frames.
  5. Export with the Instagram/TikTok or YouTube Shorts preset.

Prompts to paste

This is 16:9. Make a 9:16 version that keeps me centered the whole time. When the screen recording is showing, crop to the part of the screen I'm pointing at instead of the whole thing.
Make a 1:1 version for the grid where my face stays centered, plus a 9:16 version. Export both at 1080p.
Capture frames at 0:03, 0:15, and 0:40 so I can check nothing important got cropped out.

When to use something else

  • You want automatic face tracking with zero instructions. Some tools do one auto pass. Vyra works from your description (TODO confirm auto-tracking scope).
  • Two people who both need to stay visible. Use a split layout instead of a crop.
  • You need the horizontal version untouched. Reframe on a copy of the project.

FAQ

Is there a separate crop tool? No. Masks do the cropping. A rectangle mask is a crop.

Can the crop move during the video? Yes. Say what to follow in each section, or keyframe the mask.

What about text baked into the original? It crops with the footage. Rebuild titles as text in the vertical version.
