Sorry - that link I referenced actually did not have the whole thread. The

Unfortunately, the -noautoscale option does not work either, I've already tried that before.

It is, however, not surprising that it has no effect because -noautoscale is an output option. And in my scenario, the output resolution does not change over time.

As for the patch linked in that thread, I have yet to try it. Not sure if it's already been merged into master; if not, it means I have to compile a build myself, and setting everything up for that is likely going to take a while...

If that does not solve it - sorry - I do not use QSV (except in Plex) for
anything - I just remembered seeing that email thread a while back, so
looked it up. This one has a resolution, but I am unsure if it is software
or hardware.


No problem. What I still cannot understand is whether this is some kind of fundamental limitation or an outright bug. For some reason, I could find very little information about this particular scenario. Whenever I search for that error message ("impossible to convert between..."), it always seems to concern a completely different use case.
