Frequently asked questions
About Merge Videos
Merge Videos resolves the geometry problem that appears when unrelated clips share one timeline. Their card order becomes playback order, while canvas settings decide how different sizes and orientations coexist without distorting a frame.
The fastest compatible path concatenates streams directly. When sources disagree, the local engine normalizes them to a common video and audio structure before joining, producing one continuous MP4.
