For the recovered MOV video files, in most cases, they can play directly. In case some of them cannot play, probably the structure or header of the video files was broken due to partially overwriting, damage or crosslinking.
If your recovered video files can play directly without any problems, please discard the following message and no post process is required.
If some of your recovered video files cannot play properly, you may try to play the recovered .mov files in a different video player, or search the net and try some video repair or convert tool on the recovered files. Hope that helps.
VLC Media Player

Above tool is provided by third-party. Many of our customers reported it works for corrupted .mov or .mp4 file repair. But it is not a freeware. The trial version downloaded from their website can repair half the size of the movie file. It is available on both Mac and Windows platform.
If the recovered files have a .mov file extension but your camera uses a different video file extension, you may try to rename the extension of the recovered .mov to the original format extension of your camera (e.g. .mp4)

If still no success, sorry, probably the video files are too corrupted to recover in this case.
