Empty(Corrupted) Video and photo

[ojject]

Hi, I was recording a festival tour and after I came home I found out that some of those videos are corrupted.I have no idea how it happend.In the camera was Samsung 64GB 10class SD card .I tried using every possible method that there is but no luck.I'm suspecting the SD card to be the creator of this problem because as I plugged the SD card to my laptop running Ubuntu it said something about not being able to mount it because of bad SD card format.

As I looked for the bit rate or length of the video, its blank so video has no header.

Is there anyway or reparing my video ? Video was shot @ 1080p30

Here are links of working and corrupted video https://mega.co.nz/#!Gws0kbjJ!GEtwxs6gYPWdoAs965IVHT2GNHFRSarFzkGkXbjCUjk

Have you tried Registrator Viewer's repair menu? It will repair videos where the end is missing...

have you checked the card with h2testw?

i'm sure there is a problem with your sd card, check it as jokiin says, you'll have to replace it
btw i tried to recover your video with a video repair (from Grau) and it is not possible

I have the same experience. Can someone help me with this?

I faced the same problem. It was a time lapse video 24 fps. Can you help me to fix the file.

after digging everywhere online, i found out that it was my card. i thought i had a legit one but it was actually a replica that looked exactly the same as a sandisk extreme sdxc 64gb uhs-1... only once sandisk verified serial number were they able to figure that one out...

basically whats happening is that the cam is "freezing" after creating the file and then the sd-card cant get back up to speed fast enough to keep writing so file get's corrupt and can't play.
i've tried a bunch of video repair software to no avail
