Interesting results. Encoding on speed priority worked without crashing.
~1 hour video, speed priority using latest Waylens Studio PC with the new libraries Vicent shared:
33.9GB file, 76 mbps video using baseline @ L4.2
CPU usage ~30% on my i7-770 during encoding
~20 minute video, default priority using latest Waylens Studio PC without the new libraries:
2.33GB file, 15.2 mbps video using high @ L4.2
CPU usage ~50% on my i7-7700 during encoding
I thought speed priority would be a smaller file and lower bitrate, but the baseline profile makes sense. What do the different quality/default/speed priority change? I'm re-encoding most of the time for picture-in-picture overlays (multiple cameras in car) so maybe speed priority is good for intermediate processing.
