M50 Mk 1 Video Glitchy???

HSG1033 — Sun, 16 Apr 2023 20:02:31 GMT

Hello All,

I am in need of some advice. I have had the M50 Mk1 for over a year now and have really enjoyed using it for our Youtube channel videos. I have recently noticed a problem with the video skipping slightly or "glitching" during the recording. I can see it happen while I am shooting through the digital screen and the glitches are also recorded in the video file. I see it happen in real time so I know it is not a downloading problem. It seems to occur more at the beginning of each recording. I have tried removing and replacing the battery before recording but that didn't seem to help. We have recently started shooting at 60 fps instead of 30 fps. I am not sure if that could have something to do with it or if that is just a coincidence. I thought it might be a firmware issue but (from what I can tell in my research) we have the most updated firmware...Ver. 1.1.0. Any help or suggestions would be much appreciated! Thanks!

I couldn't find any info in the user manual about the file size per second of 60 fps footage. But one guess is that the SD card you're using may not be fast enough for 60 fps footage.

What specific brand of SD card are you using? Does it have V-rating on it (e.g. V30)?

It is a Sandisk Extreme Pro, 128gb, 200mb/s, V30. Ahhh! Should I have a V60? If this is just the card and not a problem with my camera, then you just made my day!

I don't know. V30 would allow sustained writes of 30 MBps (240 Mbps). I'm not sure what the bitrate would be when recording in 60fps. If you drop back to 30fps, do you see the same stuttering?

Did you format the card in the camera (low-level format if that's an option) before filming?

I just tried it and I do not see the same shuttering. However, I do not ALWAYS see the shuttering at 60 so I am not sure if the test is really reliable. Sometimes it seems to have no problems at all and other times it glitches 5 or 6 times toward the beginning of a recording and then it quits. The more I think about it, the more I am pretty sure that the glitching did not occur at all when we were doing 30 fps. I did format both cards we have in the camera...it just prompted me to when I first put them into it. I don't think it gave me any options about level of formatting.
