Separate encode problems from host problems
Gif not animating / gif not moving / animated gif not playing
If gif not animating, gif not moving, or animated gif not playing in a host, confirm the file animates locally first. Some CMSs freeze GIFs; try MP4 instead (see gif vs mp4).
Gif quality loss, blurry gif, pixelated gif, gif colors look wrong
Gif quality loss / blurry gif / pixelated gif often mean over-downscale or low quality slider. Gif colors look wrong is palette banding — flatten gradients, raise quality, fewer unique colors.
Gif won't upload, gif not supported, gif upload error, speed & loop
Gif won't upload / gif not supported / gif upload error: shrink via target size (gif under budgets on website page). Gif too slow / gif too fast / gif frame delay issue: adjust delay. Gif looping problem: check infinite vs counted loops. Fix animated gif by re-encoding; repair gif animation means re-export, not a binary healer.
