Videos on the canvas can now be resized for social placements the same way images already could. Select a video, click "Smart resize" in its toolbar, and pick formats across Instagram, Facebook, TikTok, Snapchat, YouTube, LinkedIn, and X. Nothing gets cropped, since each format is fit against a blurred copy of itself so the whole frame survives.
Need something a preset doesn't cover? Type an exact width and height instead — custom sizing works for video now too, not just images.
