UHD 60p

PostSat Jul 01, 2017 4:32 pm

Hi -

So I'm moving to 4K content production with a Panasonic GH5. I shoot in UHD 60P and then transcode all media to Avid DNxHR UHD 60P LB to keep the bitrate low.

I import all the files in the Avid no problem, using Decklink 4K Extreme card to playout the footage to my monitor. However, upon playing back of the footage, sometimes I see some red bars appear on the timeline, indicating dropping frames. Also, when I try to do a digital cut, the application reports "Some frames were dropped."

Using my previous workflow of filming in HD using XDCAM 50 MBPS 4:2:2, i never have this problem.
Here is my computer specs (shown below)

My computer was built in October 2013. What CPU do I need to upgrade to playback UHD 60P DNxHR HD LB without dropped frames please?

Thank you.

HD and UHD 60p is quite a different thing.
I don't know AVID requirements well, but your machine is juts to old for UHD, specially 60p.
You need bit better GPU ( e.g. GTX 10xx with 6GB RAM+) with 8 core+ CPU at 3GHz+.
