Can I put a GIF on a video background?

Yes. Choose Video and pick an MP4 or WebM file. The result keeps the GIF's own length, and the video plays behind it at about 10 frames a second. A video shorter than the GIF loops. The output is still a GIF, so it plays anywhere a GIF does.

Is my GIF uploaded anywhere?

No. The cutout model and the compositing both run in your browser. The GIF, the background and the result stay on your device.

What if my GIF already has a transparent background?

Then no AI is needed. Stickers, emoji GIFs and earlier cutouts are placed exactly as they are, which is faster and has no flicker at the edges. They are also not limited to 30 frames.

Why is my GIF cut short?

The AI runs once per frame, so a GIF that needs a cutout keeps its first 30 distinct frames to keep the wait reasonable. Frames that repeat are merged first, so more of the animation usually fits. Transparent GIFs can run to 150 frames.

Why do the edges flicker a little?

Each frame is cut out on its own, so the edge can shift a pixel or two between frames. A subject that stands out from its original background flickers least. Sharper edges uses a larger model that handles hair and objects better, and takes longer.

What size is the result?

The same width and height as your GIF. The background is scaled to fill the frame and cropped evenly on the long side, so any photo or video shape works.
