recovery of a 0kb movie which is visible on camera screen

I recorded a 37 second movie with a Hero 4 today. I can watch it on the gopro screen. However - the file size when connecting the camera is 0kb. Also if I connect the SD card to my laptop directly, the file size is 0kb.I tried to switch on the camera without the card and then put the card in - no success.

It happened during diving and I recorded some files later - all without a problem. I might have missed that repair message from the camera which only appears once.

How can I restore this file? The data must be somewhere - otherwise I would not be able to see it on the gopro screen

Re: recovery of a 0kb movie which is visible on camera screen

When you are watching on the GoPro, you are actually viewing the LRV file. It doesn't look like the mp4 video closed properly and therefore will not play. You can transfer the LRV video to your laptop and change the extension from LRV to mp4 and it will play, however it will be a low resolution video (LRV).

What SD card are you using? Is it on this list? https://gopro.com/help/articles/block/microSD-Card-Considerations#list2

How long have you been using the card? Do you format it often? Have you run a FULL (not Quick) format of the card?

You should only use cards on the recommended list for best use.
Also, you should format the card in camera prior to starting a days recording (this will delete all media from the card so be sure to transfer/save what you want first)
Periodically, you should perform a FULL format of the card in your computer to check for any bad sectors.
Over time, cards can become less reliable. Especially if you write a lot of data to them or frequently remove them from the device.

Re: recovery of a 0kb movie which is visible on camera screen

Actually, looking at your files, it does not appear that the camera was able to make an LRV file for the GOPR0026.MP4. Are you sure this is the file you are viewing on the camera?
