Is not possible to rebuild because is probably a bit overwritten
Volume was written to since it was reformatted? So they're not detected by filename? Using whatever, R-Studio, UFS, ReclaiMe etc.? If filenames do appear in your file recovery software, do run lists look okay? And if so and yet recovered files are corrupt then it's very likely portions of the file have been overwritten. No specialized carver can solve that.
ISTM then you can not even be certain portions of the videos haven't been overwritten themselves if file recovery software does not even find MFT entries for them. Which makes it hard to judge if the little chunks you did recover are best possible result or not.
Anyway. Tools do exist that carve for and try to reconstruct fragmented video, however these were primarily designed to scan memory cards. Some even for one specific device that was used to record video. MOV is quite flexible and so atoms, the parts that make up the file, may appear in very different orders which makes it kind of hard to figure out which part belongs to what file. So a tool 'knowing' how a specific GoPro formats the video helps recovery while another tool designed for a different device may fail recovering GoPro video.
Typical fragmentation of video files are result of a combination of factors: The file system they're written to (so some flavor or FAT probably) and the nature of recording video, where in advance it is unknown how large file will be. However once you copied such a file to a hard drive, this fragmentation will be largely resolved as OS driver now has the chance to look for a chunk of clusters large enough to accommodate the file.
The carver can still fuck up because it may apply very simple rules for end of file detection, and assume a certain layout of atoms. If you'd take one intact file shot with same device and examine order of atoms, you may be able to carve using a disk editor.
These make specialized MP4/MOV carvers:
