Only partial restoration? #134

First of all, thanks to the maintainers for working on this! Seems like most of the software like this hopes to make a chunk of change, or worse, lots of change (and annually) to assist with this kind of problem.

I have a Sony ZV-1 and I was filming at 4k, 60mbps for over an hour when I received the "corrupted" message on my camera. The file is 37GB. Using this tool, the recovery produced only a 7 minute file. I'm wondering if anyone has had a similar experience and if the tool can restore more than 1 sequence. Ultimately, the 7 minutes was not useful footage, but seems like if the tool was able to restore this much, it should be able to restore more or maybe the tool can't pick back up after it encounters an error... i.e. rescue from error, and continue on the rest of the file (resulting in potentially multiple restored clips)?

Again, thanks for everyone's hard work on this!

I have similar issue, it was able to recover few seconds of video when the video is about 20 mins.

I have the same issue from a Sony FDR AX33. The file is 89GB (it's constant footage from a tripod for 4 hours) and using Untrunc gets me back a 7 minute 4 sec file. I have used restore.media and fix.video to get a preview of the file, and both programs manage to get the complete 4 hour video back, give or take a minute or two, so I know everything's there somewhere.

I just don't know how to get it done. I want to try to do it myself before shelling out $145.

If anyone knows how I change the download directory for the fixed file to an external harddrive (what command in Terminal?) that'd be appreciated, too.
