EOS R50 Video clips with file size of 0

[elijahrockers]

Hi, just testing out my new camera.

I just returned from playing pickleball with some friends. We played three games and I attempted to record all three games to a 64GB SD card (200MB/s). I stopped recording between each game. The camera created three associated files, but the files are practically empty except for the thumbnails.

The first one is 3 seconds long, at about 50MB (I'm recording at 4k, 29fps) and the other two are 0B filesize. But somehow the thumbnails are there...

Anyway, from some back of the envelope calculations, it looks like the SD card should have been able to fit all three games on there. One thing I did notice is that when I plugged the camera into my PC, the OS showed the card was about 50% full, even though it only had a couple GB worth of files on it (There were a couple other very small video clips of me basically just testing the record functionality for a minute or two). I copied everything the OS recognized over to my storage drive, and reformatted the card using the camera, so if there were some hidden data I wouldn't be able to recover it, and anyway the clips are not that important - I'm just testing the video record function out.

Couple other things, it was about 68 degrees F outside, but I placed the camera in the shade. And I was kinda keeping my eye on it the whole time to make sure nobody knocked over the tripod, etc.

Any ideas what happened with the these clips? This is the first time I tried to use it to record any extended length of video outside, and I'm a computer scientist but I can't really think of any reason it would've generated three empty files.

found the utility, didnt solve my problem

the eos utility does not even show the videos. but they will play on the camera. and if i try to strip them directly with a file explorer, the videos are presend, but listed with 0bytes, and only a thumbnail. video wont play on computer

I noticed this and have been using the eos utility or the card reader to copy those kind of videos, that is, larger files. Small size video size have no problem getting copied over the usb cable connected directly from the camera to the PC but the larger ones get copied with a 0byte in size.

Does any one know a way to recover the video? Before I discovered it I had copied an important video and formatted the card, I am left with the 0 byte video.

Hey waddizzle, just to follow up on your suggestions, shooting an the fully auto mode has the same problem when the camera is set for 4k30. If I go down to HD resolution, it seems to work though.

I'm leaning towards it maybe being a USB issue and I've got a card reader on the way to see if maybe that can help, since the videos playback fine on the camera body.

What specific card are you using? And what is its V-rating? The 200 MB/s value is only a theoretical read speed. Perhaps your card is struggling to keep up with the writes.

After re-reading this, it could be that you don’t have proper permissions set up for the destination folder/directory.

Or, perhaps the files are too large for the format of the destination drive?

It seems that I am unable to copy them to my large storage SSD because the operating system doesn't see the data in the first place. I can copy the files over but they copy over instantly because the OS thinks they are 0 bytes. This is essentially the same issue I'm having on my OS drive (which would quite possibly have filled up from a few of these videos)
