Have I set my Ninja V wrong?
Posted: Tue Apr 13, 2021 10:15 am
I am unable to record 10bit 4:2:2 at 50 frames per second from my Panasonic GH5 to Atomos Ninja V.
So far I have tried eight different HDMI cables at 2.0 and 2.1 certified to 8K.
When pressing record, the signal drops out and stops recording after a few seconds, and I don't know why.
The links in the chain are:
the camera
the cable
the SSD card
With the camera, I have just bought the vLOG profile. I was using HLG but still had the same issue.
When shooting 50fps I have the camera set to:
3840x2160,50.00p
420/8bit/LongGOP,150Mbps
I have three HDMI cables to test all certified to 8K
My Ninja V is set to record:
Pre Roll On
ProRes HQ (IS THIS OVERKILL and my problem for home movies and YouTube?)
My SSD is a Samsung 870 QVO 1TB
I used Crystal Mark 8.0.1 for the following Write Speeds:
SEQ1M Q8T1 - 410.83
SEQ1M Q1T1 - 394.87
RND4K Q32T1 - 169.63
RND4K Q1T1 - 52.70
I have an older Samsung 860 QVO which is approaching two years old. Its write speeds are slightly better than the new SSD, so I'm happy to swap out the SSD's if this will help solve the problem.
