Merging 2 files

[Everillangel]

Hi, I really appreciate this software. I have a file recovered from an SD card im trying to fix. The issue is its off an FX3 and the recovered files are split in 2 one with the video data and one with the moov atom and neither seem to have the isomedia file.

Here is a working file (cam 4), The data file (file000000.mp4) and the moov atom file (00.mp4)
