XAVC render problem 17.1

PostTue Mar 16, 2021 7:07 am

Rendering from a final DNxHR master to supply ABC TV with a broadcast Sony CBR 100 XAVC 1080 50i master. The 50i image has lots of wrong frames. Frame order jumps around. Only a problem so far with this codec. Unfortunately it is the delivery codec specified by the broadcaster. Clearly a bug and independent of hardware as it does it on both my Windows desktop and laptop.

Anyone else having this issue?

Give the new MainConcept encoder plug-in a try. It's much better at encoding such typical broadcast standards.
My disaster protection: export a .drp file to a physically separated storage regularly.

Yes, I saw it as well. The frames just go nuts. Clearly something is off. Hope this will be fixed soon.

I have the beta versions of these but they gave me an error message saying failed to render. I didn't have time to investigate but used Shutter Encoder to do the AVC Intra render which worked. It is worth getting bugs notified and fixed as well

I got the final version of MainConcept here for testing.
Which codec did you encode into, RP2027 AVC-Intra or Sony XAVC-Intra? Was your timeline set up for interlace as needed in 17?

Just tested it with the new 17.1.1 release. Still a problem rendering this as an interlaced codec. Release notes say improvements and bug fixes with interlaced timelines but this one isn't fixed yet.
