Extend the Frame

You filmed the whole vlog vertical, and now the YouTube thumbnail needs 16:9 and every frame grab is a tall sliver. Cropping loses your face; letterboxing looks like a mistake. Expand the Frame paints in what the camera would have seen on either side: more of the wall, the desk, the street, the sky, matched to the perspective, the light and the grain of the original. The pixels you uploaded are untouched in the middle; the new area grows outward from them. It also goes the other way, turning a wide landscape shot into a tall Story or a square post into a 4:5 grid post without losing a thing to the crop.

The expand-to select lists the ratios you actually post in: 16:9 for thumbnails and banners, 9:16 for Stories and Shorts covers, 1:1 and 4:5 for the grid, 4:3 and 3:2 for a more classic photo shape, and 3:4 and 2:3 for portrait prints and Pins. Pick one and the tool works out where to add canvas, top and bottom or left and right, so the original stays centered and its scale is preserved. New content continues surfaces, textures and background elements; it will not add extra people or invent a second copy of you. Simple, consistent backgrounds expand cleanest. Busy scenes with lots of text or repeating detail take a couple of tries.

Start at Standard for 4 credits and look closely at the seam where the original meets the new area; if a line of the desk or floor bends, run again. Pro is where the finished thumbnail should come from. Once the frame is wide, send it to Thumbnail Maker to lay in the title, or Banner Maker if it is going up top on the channel. If you only need a different crop and nothing new painted in, Reframe is cheaper and faster. Upscale after expanding, not before, so the extra resolution covers the new area too.
