Thank you, Andrea, for starting a new thread and a reminder to myself and others that if your reply is not related to the Subject line, it is best to start a new thread. Otherwise, I am having a hard time finding something when I need to get back to it !

Yes, my libva is out of date because my O/S is old, but on a duplicate laptop with a partition loaded with current Fedora 38, I do see av1_vaapi as an encoder. > > I am attaching a new version of the preset for av1_vaapi, but there > are many conditions for it to work: you have to install CinGG > (appimage is no good, unless you know how to open and recreate it); > new generation GPU (Nvidia 4000; AMD Radeon 7000; Intel Xe 2 or Intel > Arc); system with updated libva (possibly Rolling...).

This verifies that it does process the parameters for correctness before it fails on the hardware. So I will be checking these into GIT -- the user can easily change values to suit their needs. Too many of the newest speed-ups are so hardware dependent which is so varied for everyone. Not too many people want to update their graphics board all of the time at $500 or so a pop and then struggle with updating the software too.
