Hi,
DVR version: 17.3.1 build 5 (Studio)
OS Version: OS X Big Sur 11.5.2
CPU: 2.4GHz 8-core i9
RAM: 64GB DDR4
GPU: AMD Radeon Pro 5500M 8GB
Type of storage drives: Internal 2019 16" MBP SSD media (project & cache), external Samsung EVO pro SSD (project media).
Project is running 1080p25 timeline, and exports are the same res/fps, attempted in H.264 both .mov and .mp4 and .mov ProRes codecs. Only corrections currently applied in colour tab are a LUT from SLog3>LC709A. No other FX applied.
The project uses a mix of FS7 footage (my regular camera), plus FX6 footage (hired in for this job). Both cameras shooting UHD .MXF files, with the FS7 codec showing as "XAVC High L5.1" and "XAVC Intra 4:2:2 L4.1" (from two different shoots), and FX6 all as "XAVC Intra 4:2:2 L5.1".
Problem is occurring only very occasionally during playback, and consistently on export. It ONLY manifests in the FX6 clips being used, NEVER in the FS7 clips. It is a glitch / stutter / frame skip, where playback displays 3-4frames twice in quick succession before continuing playback. There is no noticeable glitch in audio.
I'm currently exploring workarounds starting with transcoding the relevant source clips into ProRes, but obviously a permanent fix would be hugely desirable. If anyone wants a source file to test replicability then just ask.
Thanks,
jason
