Mov file recovery issues

[lironzz]

HI everyone
I have been trying vigorously to recover some files off my corrupted 16gb microsd card that i used with my olmypus tough camera.
I have successfully recovered all jpeg pictures but there should be some 80 odd mov files that I am facing difficulties with.
I am using photorec 7.1 on a windows 7 64 bit OS. When i recover them about 80 mov files come out all with names like f8804480_ftyp and they all seem to show the right file type, length of play, size etc although when played they show a black screen and white noise.When I choose to show mdat files separately in photorec then about 199 files show up but they are all named the same with names like f8804480_ftyp. They all show fairly large size files with expected time of play etc and so far i can't see any distinction in these files that could help me match them up.
I am really hoping somebody could help me out here.
Thanks!

Try to concat the mov files as explained in https://www.cgsecurity.org/testdisk.pdf chapter "Recovering lost videos from a memory card using PhotoRec"

Thanks for the reply, but I have read that and followed the instructions. My issue is with what happens after i recover the files and being able to distinguish them. There is no indication which files are Mdat that i can see. All files are atleast a few MB and names are the same. Although when separeted the number of files is almost tripled.

Still having issues, was wondering if anybody has any suggestions?

You need to use latest 7.1-WIP, not an older version.

Thanks for the reply again. But this is the only version that I have used and it is still not working out for me.

You can enable the option "mov/mdat Recover mdat atom as a separate file" in FileOpts from PhotoRec 7.1-WIP and try to concat the recovered files as explained in the pdf.

Im having the same issues, every video is coming with the correct length but just black screen and white noise, has anybody figured it out?

haydomiata, did you try what I suggest previously:
