Desktop MP4 Video Joiner vs Online MP4 Merging Tools

- The files to be merged must have the same format (such as MP4 file with the same codec), file size and frame rate. It is way harsh because it is almost impossible to meet this requirement.
- The size of MP4 video file is limited to 200M, which defeats HD video recording and movie merging.
- The merging process is quite slow. It is frame by frame technique that seems to be used, which make it extremely time consuming.
- Even after repeated tries, it still fails to merge MP4 video files.
