Do you have two or more MP4 files that you need to merge? In today's video, we'll show you the easiest and quickest way to concatenate and merge multiple MP4 clips. No re-encoding is required and no quality loss occurs.

Note: If the video clips have the same encoding (for example, they were recorded from the same device), they can be concatenated without re-encoding. Otherwise, transcoding will occur and the process will take longer.
