After eight years of recording and deleting video on a Panasonic HDC-HS80, running assorted data recovery software has yielded a couple thousand m2ts fragments, most of which are unplayable. Obviously, the smallest of these contain little or no actual visual data but I'm interested in viewing the ones that do. I hope to salvage even individual frames if that's all that's possible. I've been looking into comparative hex editing and searching for time code info but (being new to this) I feel a bit out of my depth.
Any suggestions on how to proceed would be greatly appreciated!

Wow! Had never used photorec before. Did an amazing job on larger video fragments but actually recovered fewer of them than other programs I'd used. Possibly just need to dial in the scanning options. Really interesting program. Thanks!
R-Studio is generally excellent for both metadata based recovery and raw / signature based recovery, but for a few file types which have a sort of “modular” structure (a new header for each chunk of data), like MPG, VOB, and MTS/M2TS, it gets confused and can extract thousands of small fragments (considering that one header = one file) instead of recovering the original files as a single chunk, even if those were not fragmented. Of course, the problem is compounded if there's fragmentation involved, which is highly likely “after eight years of recording and deleting videos”...
But I'm not exactly sure of what you intend to do... Do you need to recover a particular clip, or is it just out of curiosity, for the sake of science ?

Yes, definitely more for the sake of science/a more avant garde style video project, exploring the aesthetics of corruptions, distortions and data moshing which can be sort of accidentally beautiful. As far as "intact" video is concerned, I've had really similar results from Disk Drill, Recoverit, Ontrack Easyrec, EaseUS, and now photorec. What I find really interesting (and what I need to educate myself about) are the differences between the programs' algorithms. Each has a very different idea of what is "useable" and since I'm looking for video that most programs would consider garbage (overwritten and truncated) it's proving challenging but fun all the same. Of all the recovery programs I've tried, EaseUS Data Recovery Wizard yielded the most viewable fragments. What I dream of (and which probably does not exist) would be a recovery system which, beyond recognizing individual frames of visual data, ignores file structure almost entirely and shows you 100% of your drive contents. Don't know if such a thing exists without getting into forensic software. In lieu of this, I may keep trying to learn how to fix m2ts streams in a hex editor though I'm not having much luck.
