Frequently asked questions

How does it make the GIF longer?

By repeating the existing frame sequence until the target length is reached. No frames are invented, so the motion is identical, it just loops more times.

What if the target is not a whole number of loops?

The last repetition is cut where the target lands, so a 3 second loop extended to 10 seconds gives three full passes and a partial fourth.

Does the file size grow with the duration?

Yes, roughly linearly, because each repeat writes the frames again. A 10x extension gives you something close to a 10x file.

Why not just set the loop count instead?

Loop count is a player hint that some contexts ignore, and it cannot give a fixed running time. Baking the repeats in guarantees the duration.
