Hi folks,
Unfortunately we didn’t found a solution yet for our ATEM-problem. Here is a very short movie with the problems:
Remark: both camera’s (Panasonic PTZ & GoPro Hero 10) are set 1080p50 on hdmi-output. The ATEM records in 1080p50. So CPU-calculation due to synchronization shouldn’t be an issue?
What did we try?
- ATEM of the music club + SSD Samsung T5 (2TB) of the music club (formatted exFAT) = flickering REC button (movie part 1) >> we have footage on SSD after a hard reset of the ATEM
- ATEM of the music club + my own T5 (2TB) (also changed the usb-c cable) = REC button hangs (movie part 2) >> we have barely some footage on SSD after a hard reset of the ATEM, recordings lost
- my own ATEM extreme ISO + SSD Samsung T5 (2TB) of the music club = flickering REC button again >> we have footage after hard reset
So I don’t think it’s the ATEM of the club (my own ATEM has the same issue) and it’s not the SSD T5 (2TB) of the club (my own identical SSD has the same issue, both formatted).
I’ve bought my own ATEM + 2x SSD T7 (2TB) in March 2021: we never had an issue with a T7, despite all the bad comments on the BM-forum (till January 2021, maybe a firmware update solved this issue…didn’t found info about this online). Tomorrow we have another try and I’ll work with my Samsung T7 (2TB) on the ATEM of the club.
A colleague of mine told me to lower the fps from 50>25. This could theoretically avoid the problem, but I want movies in 50fps.
Three unsolved questions so far:
- why is a T7 not in this list:
https://www.blackmagicdesign.com/support/faq/59032 ? Why is a (slower) T5 still recommended? I have T5’s to connect to my BM Pocket Cinema 6k cam directly, for the ATEM I’ve always used a T7 myself.
- Why is a 2TB never listed? Benchmarks give +/- the same read/write results for a 1TB or a 2TB version, or am I wrong here? A T7 is much faster than a T5, that’s sure.
- why did the ATEM + SSD T5 of the club worked for hours (!!!) without a glitch at my company’s place?? Could this be related to 1) specific local camera input (??) or 2) local power grid failure (????).
I'll keep ya all posted!
