I noticed today that when I chose H.265 / HEVC for export, that even with Software Encoding enabled, there is only the option for 1-Pass VBR, not 2-Pass. I am using Premiere Pro 23.1.0 Build 86.
However, with software encoding, even with 1-Pass there is the additional "maximum bitrate" slider that does not appear when Hardware Encoding is chosen. Which I find strange, because with h.264 at least, usually the maximum bitrate slider only appears with 2-Pass.
Is this a bug, or does H.265 use a different method of encoding for which this makes sense? Perhaps someone could explain.
Also apologies if this has been asked before, but all the post I found seem to be talking about hardware encoding.
