Can't Play Files
« on: July 06, 2017, 05:57:47 PM »
I cannot play several of the files from my last outing with the Chronos 1.4, has anyone encountered this and do you know how to repair/recover the .mp4 files?

Some of the files play just fine and I didn't change anything with regards to saving since my last successful trip (memory card, format, etc).

Any chance you can upload the failed files somewhere? I'd like to investigate.

I had one report of failed files if you ejected the card too soon after a save completed, did you do anything like that?

Edit: One more question, any idea how long (how many frames) the clip was? ie. how far between mark in and mark out?

You can try recovering the files with the utility recover_mp4. This is a somewhat complex command line utility however. If you sent the files I can try running it on them.

I can email one to you, if you can help that would be amazing since this footage cost me a lot of money to capture and it's very important to me.


I did eject the card soon after saving, I didn't know there was a requirement to leave it in. The camera should still say saving if it's not complete IMO.

The clips are about 2000 frames IIRC.

I've added this to the bugtracker so we can fix this bug.

For others who may have this problem, two of the three files were able to be recovered with recover_mp4 from the above link, so give that a try if you're having problems.

Awesome! That works on files that 'missed' the mark out point, thanks!

William,  I have found that if you remove the SD card before you shut down the camera,  the file will not be playable.
