Camera Drops Frames. Doesn't record

PostThu Dec 02, 2021 11:37 am

I was wondering if the USB C cable affects the performance of my Samsung T5 1TB drive? I can only record up to 45ish seconds before it drops frames and stops recording. Should i really be buying CFast 2.0cards?

Thanks

Can be. Try another cable first.
No, an iGPU is not enough, and you can't use HEVC 10 bit 4:2:2 in the free version.

What video settings are you trying to rec?
Video resolution, frame rate, codec and compression.
That can help people looking into the problem

It's important that SSD is used as a recording media and not a general purpose drive.

I use 2 Lacie SSDs, a 1T and a 2T and though they are not on the list I have never had a problem, but my SD cards fail when filming in slomo above 60FPS. Could be speed, or the cable so as someone said that is the easy test first.

Well, if it’s not listed anything can happen. SSDs are aging and the remapping used for cells going bad can change their performance.

Ok thanks for the tips, i did inherit the camera from the last employee, so I'm playing catch up and learning this camera as i go. the SSD was on the approved list but i had to buy a new cable for it, i didn't realise this could be an issue.

The camera was at 50fps and was in Pro Ress at 422 which i have now changed to 25fps and Proxy setting. I'll try recording again and report back.
