Definitely. That’s probably the best advice in this thread.
Whatever you decide, don’t overwrite the original file. Keep a backup and work on a copy.
Interesting. I didn’t know using another clip from the same camera could actually help.
I’ve also seen people recommend it for drone footage and GoPro recordings. Not every case is recoverable, but it seems to handle structural corruption better than general media players.
I’ve heard about the sample-file approach before. Makes sense since the software can compare the healthy recording with the damaged one.
I ended up using Stellar Repair for Video because it supported sample-file repair. I had another clip from the same camera recorded with identical settings, and that helped recover most of the damaged footage.
Which one did you use?
I’ve only tried VLC and FFmpeg before.
In that situation I eventually used a dedicated video repair application instead of media players. It analyzed the damaged file instead of just trying to play it.
That explains a lot.
If the recording wasn’t finalized properly, free tools sometimes struggle because the file structure itself is incomplete.
Exactly.
Battery died while I was filming.
Before rolling back Windows, I’d recommend updating your GPU driver, monitor firmware, and chipset drivers first. If none of that helps, uninstalling the latest cumulative update is probably the safest temporary workaround until Microsoft investigates.
Did the recording stop unexpectedly?
That’s usually when the MP4 header gets messed up.
If a Windows update suddenly drops your monitor from 400 Hz to 240 Hz, that’s incredibly frustrating. High-refresh displays aren’t cheap, so I’d probably roll back the update until a fix is available.
Same here. FFmpeg is worth trying if you’re comfortable with command-line tools, but it only helped when my file wasn’t badly damaged.
Quick update—I tried VLC first with no luck. Then I tested Stellar Repair for Video using another clip from the same camera. It took a while because the file was large, but the repaired version actually played. Lost a few seconds near the end, but the important footage was there.
Thanks, everyone, for pointing me in the right direction.
