Here's a quote from the article:
since in the current beta, it defaults to using the NVIDIA/AMD GPU over Quicksync if it is available.
So, according to that, in latest beta, with hardware encoding selected, even if Intel's iGPU is enabled, it should use graphics card's encoder by default.
I haven't tried it yet (don't want to mess with current project), but I'm very excited about this.
I've been using Voukoder 1.1.3 for several months now and it made export so much more effortless.
I still see many benefits to use voukoder because of FFMPEG and ability to use QCP instead of set bitrate.
I wish Adobe would add quality-based setting, but I guess it's just against how AME works.
