Caution

MP4 Join Tool will look for split MP4 files in the selected folder and in subfolders under it (up to 3 levels deep).

The destination folder must be on a drive with a file system that supports file sizes of 4 GB and larger.

Caution

A subfolder will be created under the Destination Folder and the joined (or copied) files will be saved in this subfolder. The subfolder's name will indicate the date of the operation ('yyyymmdd' format). (If you perform multiple join operations on the same day, a suffix starting from '_1' will be added to the subfolder's name.)

5. When the confirmation message appears, click OK.

Caution

If part of the split files that compose an MP4 clip are missing, only the existing files will be joined, creating a partially incomplete MP4 clip.

The maximum continuous recording time of an MP4 clip is 6 hours. After that, the recording continues as a separate MP4 clip. These are not considered split clips and cannot be joined with this application.
