GoPro HERO 11 Mini does not split recordings #934

Closed KillzoneKid closed 1 month ago

KillzoneKid commented 1 month ago

During long recording it creates a singe file of 4.29GB size (4,294,967,295 precisely, tested with 2 different recordings) The file is corrupt and won't play, I guess it writes over it instead of creating a new file. Tested with latest firmware, Max Lens Mod, 2.7K on both 30 and 50 fps.

That doesn't sound like a camera failure. Likely bad media or a bad format. With FAT32 formatted cards used on 32GB or less, the camera chapters at 4GB, with 64GB or greater exFAT formatting is used, and it will chapter at 12GB. This seems like it is a 32GB formatted as exFAT which is not supported. Some fake card may behave like that. Here is a list of recommended cards https://community.gopro.com/s/article/microSD-Card-Considerations?language=en_US

Media is 256GB genuine SanDisk Extreme Pro formatted correctly with GoPro. Works fine with my normal GoPro 11 and splits recordings as expected. I have 2 of those, both work fine, but 11 splits it, 11 Mini doesn't. Files just under 4GB all record and play correctly.

Then that could be a camera failure, although a particularly weird one. This is not standard behavior. As you are on Labs try !M64BT=3600, this should force chapters before the 4GB boundary.

Ok, thank you for helping, I think I found the problem, but I do not know if this is directly GoPro related. I used USB connection and Import feature on my MacBook to transfer the videos. This is where it was transferring 4.29GB file and it wasn't playable. I have just made a long recording over 12GB in size, it split it in 2 files, the smaller one 2 something GB imported fine, but the larger one which is 11.9GB imported as 4.29GB and of course wouldn't play. When I removed the SD card and accessed it directly as a drive then I could transfer all videos fine. So I don't know if the USB connection from GoPro only transfers 4.29GB or the Apple Import software cannot import large files (doubt this). Feel free to mark as resolved unless it is GoPro issue.

I had heard that the MTP (USB transfer proto used) didn't support greater than 4GB files. This was the case when Labs added larger chapter sizes before the main camera. It wasn't aware that this was still an issue. MTP transfers is not a Labs function, so we can close the ticket. Interesting, happy to hear you have a workaround.

Thanks again, I can live with this problem.
