Join video clips into one file
Combine several clips — even with different resolutions or formats — into a single MP4. Clips are scaled to a common size (letterboxed to keep their aspect ratio) and joined in the order you choose.
Why did my merged video lose its sound?
If any clip has no audio track, the merged video is produced without audio so the picture stays in sync. Add a silent audio track to that clip first, or remove it from the list.
