Canon XF-AVC from R5C Flashing

In 22.5, Windows 10, my footage from a R5C, UHD/23.97 422 10bit Intra, plays back with intermittent flashing. The only way around it is to change the sequence to preview at Microsoft AVI Intel IYUV codec. I have to hand this project off to an editor on a MAC... not sure how that will play out. Footage looks great when previewed in Bridge. Adobe? Is there an update for this? Problem with the R5C footage? All video drivers are up to date btw. anyone else having this issue?

Correct answer Ann Bens

Update: I did get it to playback with "software only]" but still had the flicker. Rendered the clip, and still had flicker. 5 second MXF file is here: https://www.dropbox.com/sh/on0dz3gzt3a3cuk/AADSLkPpXMyBmMrDILyg9fHGa?dl=0


Not seeing any flickering on 22.5 or 22.6 on windows.

Have you got the xf avc codec installed?

 

clip is awfully jittery but no flashes.

Set preview codec to Prores instead.

Hey brusiephoto,

 

Sorry about the issue. Are you having this issue with a specific Preview File Format and Codec? If so, can you let us know which one it is? A screen recording of the problem could help us understand it better. Also, could you share your system specifications (CPU, GPU, RAM)? We're here to help!

 

Thanks,

Ishan

Windows 10;  Ryzen™ 9 5900X Processor, 12-core / 24-thread @ 3.7GHz, (4.8GHz Boost); 64GB DDR4-3200MHz (4 x 16GB); 8GB EVGA® NVIDIA® GeForce RTX 3060 Ti w current Studio Driver; SSD OS drive; 4TB SSD Raid 0 Media Drive(internal).

I have tried all sorts of preview codec combinations, to no avail. I had it go away for a while in the project through some weird sequence setting voodo... closed the project, opened it again, thru a few cycles. all was good. Then in order to test this issue I created a new project and imported the footage and it was off again (see the attached video from that project) Then when I reopened my actual work project, the issue reappeared. I changed NOTHING in that project file. just close, and open...

BTW, when I scrub through the footage in Media Encoder, it looks fine. Proxies were generated, and they are fine too.
