Fix GoPro Hero MP4 File Errors and Recover Lost Videos

Hey guys, welcome back! In today's video, I’m going to show you how I recovered lost MP4 video files and pictures on a GoPro Hero action camera. I’ll also explain how to fix corrupt MP4 video files that won't play.

Let me walk you through the exact situation. After returning from a vacation in the Bahamas, I attempted to transfer all my MP4 videos and some pictures from my GoPro Hero 11’s SD card to my computer. However, when I inserted the SD card, only one photo was visible—despite knowing there were at least 114 MP4 videos and several dozen pictures, including time lapses and hyperlapses.

The SD card’s storage clearly showed used space, indicating files were still present but not visible. After a short panic, I looked for software that could recover the lost files. I chose a program called iMyFone AnyRecover because it was affordable and had solid reviews.

The recovery process took around 16 hours. In the end, it located all my MP4 videos, images, and some miscellaneous files. However, only 30 out of 114 MP4 videos were actually playable. The rest were corrupt and unresponsive.

I then discovered something interesting: every MP4 file had a corresponding LRV (Low Resolution Video) file with the same name. These LRV files serve as lower-quality backups. To restore functionality, I simply found the LRV file that matched each corrupt MP4, renamed its file extension from ".LRV" to ".MP4", and the video became playable.

I applied this technique to about 80 files. Of those, 77 videos worked flawlessly after the LRV-to-MP4 conversion. Only three couldn’t be salvaged.

So if you're dealing with GoPro video files that appear corrupt or won’t play, this is the easiest and most effective method to fix them.
