One recording, every aspect ratio: 16:9 vs 9:16 vs 1:1
A single whiteboard recording can be exported to every common aspect ratio — 16:9 for YouTube, 9:16 for Shorts and TikTok, 1:1 and 4:5 for feeds — because Excalicast re-renders frames from the operation stream rather than cropping a fixed video.
Why platforms need different ratios
Horizontal 16:9 fits YouTube and desktop players. Vertical 9:16 fills the screen on Shorts, Reels, and TikTok. Square 1:1 and portrait 4:5 perform well in social feeds. Posting a 16:9 video to a vertical feed wastes most of the screen.
Reframe, do not re-record
In Excalicast you pick a crop frame before recording so you know what is in shot, but the underlying operation stream covers the whole canvas. At export you choose any ratio and the frames re-render to fit — one take becomes a YouTube video and a vertical Short.
