QUICKSYNC H.264 SOFTWARE
Right now there is no way to turn off the hardware encoding and only use the software encoder for Intel a question, you say that QSV hardware is not part of Intel GPU, is it possible to disable the GPU in the motherboard BIOS and still be able to use QSV? I ask the question since I usually tend to disable hardware I do not use in BIOS to save on energy, (less heat), and resources. Vegas rendering templates allow you to specify the bit-depth you want to use. For Sky Lake processors, only 8-bit HEVC is supported on hardware 10-bit is done via software (also provided by Intel currently), and is much slower. Assuming you have a Kaby-Lake processor, you should be able to use the QSV hardware for both 8-bit and 10-bit HEVC encoding/decoding. So measuring GPU activity will not let you track it's usage accurately. The QSV hardware is not a part of the Intel GPU, but a separate dedicated piece of silicon sharing the processor die. I am one of the developers working on Vegas, and would like to clarify a few things:ġ) "Intel HEVC" will use the QSV hardware, if available, or else use Intel's software implementation.
Now we have 4K footage to encode, software encoders are just very slow to be that practical.
QUICKSYNC H.264 UPDATE
Then a few months later an update is out for the x264 encoder and I'd come across another glitch or issue. Eventually a x264 developer picked up these issues for me, found the bugs using my sample footage and fixed it. For example after hours and hours of encoding using x264 (before QuickSync was really a thing) I kept finding various glitches when playing back. Where something like QuickSync excels is in reliability and speed. However the days of needing to compress HD down to a couple of thousand Kbs or less is long gone for the majority of us. If you are going for the smallest possible file size then QuickSync just isn't designed for that and software is better. Providing the bit-rate is reasonable, the quality is very good and hard to tell apart from a software encoder at the same settings and considerably faster to encode. Newer Intel processors (Skylake and newer) have better quality now for Intel QuickSync, just make sure the quality slider is all the way to the best setting.
QUICKSYNC H.264 PRO
There are dodgey 3rd party hacked NVENC encoders that break with upgrades that require 3rd party software that can make hardware encoding work but premiere pro deliberately don't offer hardware encoding as an option & for good reasons
QUICKSYNC H.264 HOW TO
Ask yourself why does premiere Pro not use hardware encoding, Is it that Adobe was too stupid to work out how to do it, or did they respect their software too much to implement. Unfortunately this 'hardware encoding' promotion that vegas does is aimed at the ignorant. With an I7 though it's likely you could still use software encoding just fine.
Hardware encoding I've decided is only reasonable where there is no other option such a when gaming where a CPU may be greatly loaded down.
Obviously not HEVC with vegas but I wouldn't expect software encoding quality so why bother. Didn't see a problem.īut with Vegas where the source is of extremely high quality QSV H.264 is of very low qualiity compared to software encode. I capture encoded with QSV with HEVC & h264. I was a big fan of QSV as I only used it for screen capturing using bandicam & it looked just fine however I was capturing livestreamed video that was low quality to be with, often with streaming encode speeds of 3500kbit/s or less.
