Video
Join several GIFs and images under one frame, like a long product page — each part is saved as its own file.
Crop: drag on the preview to keep only the part you need (square handles resize). Result: drag text and images to move them; double-click text to edit it in place.
Part order
Click a part to edit its range, crop, speed and text. Width, quality, frame, corners and target size apply to every part. Parts with no motion are saved as a single image (PNG or JPG, whichever is smaller) instead of a GIF.
Gap between parts0%
At 0 the parts join seamlessly. Gaps are filled with the background color.
Split a long video
seconds each
If one video is too long to fit, cut it into several parts stacked top to bottom. Each part is its own file, so each one fits the target size.
