Possibly damaged files.
Here are the initial findings: one was a total failure—I played it in VLC and got just audio, which is much better than the buzzing I experienced. The other showed promising signs; the screen displayed mostly green with occasional glitches, and video flashes briefly. Audio was clearer than the first attempt but still had some issues like repetition. I’m considering using a different MP4 file for comparison and will share the results once ready. Thanks for all the support you provided—it really helped me move forward.
Consider exploring alternative software designed to retrieve deleted files. These options might approach the task differently, potentially yielding improved results. Recuva is a common choice, yet countless similar tools exist. It’s likely all recover the same files, but outcomes can vary. A simple method to verify identical data recovery is using PowerShell with the Get - FileHash command. If the hashes match, the files are likely identical. This could save time, though it’s uncertain if any program recovers data precisely the same. Additionally, if the files were deleted from an SD card and data has already been overwritten, recovery might be impossible without professional help.
You might also consider using a tool such as Repair Corrupted Video Files from the SD Card Easily [2023] (wondershare.com). Many of these programs offer free trials to test their effectiveness. They could potentially recover more data than the FFMpeg approach, though I believe that method is quite reliable.
