Enable QSV on AMD motherboard and gpu???

I have a 1:52 length 4K project that renders in 1:21 with Magix AVC mp4 VCE with 'allow legacy GPU rendering' checked and 1:54 with it unchecked. The only content in my project is Lumix S1 4K 30p footage, vegas color curves and vegas saturation adjust.

Interesting, I will have to test this on mine.

I did some tests. I noticed no difference changing legacy gpu rendering, or adjusting the RAM preview numbers. In both cases my 1080p 29.97fps VCE render clocked in at 41 seconds on my Ryzen 7 1800x/Radeon 7 system. I tried legacy GPU rendering on the Sony AVC codec just to compare, and it clocked in at 1:06. CPU only was 1:10. This using the latest version of Vegas 16.

Currently I have (2) 4K screens connected to Vega 64 & (1) 1080p screen connected to the onboard Intel for QSV. I haven't had time to find a hack to keep the Intel GPU present in Vegas if I disconnect the 3rd screen... If anyone knows how to do this please let us know...

This was supposedly a solution to the problem 5 years ago for another piece of software, you may as well check it as a possibility

I tried 'allow legacy GPU rendering' on and off with the Red Car project and it didn't do anything. I then turned off the Vegas Color Curves and Vegas Saturation Adjust in my 4K project. Again there was no time difference between on and off.

 

Definitely appears that some of the Vegas effects are where this 'allow legacy GPU rendering' helps.

 

Cheers, Pete

I didn't try it on one of my own projects. Might try that next.

Been testing that very thing myself with an asus z390-chipset motherboard with onboard video but I have only one 4k monitor. Found the best and most reliable performance for me was to connect to onboard and leave the Radeon VII unconnected. That way Intel quicksync worked with the Sony AVC (allow legacy gpu checked in general settings) as well as in the Magix AVC presets with the same lowest render times. Next best was to connect both to different hdmi inputs of my BenQ monitor while setting Windows to duplicate the screens. Sony AVC, however, reports quicksync as unavailable but the Magix AVC QSV preset finds it and performs the same high-speed render as before. Also tried with the Windows "extended displays" setup but that was kind of squirrel-ly for me, especially if the 2nd display was a different lower resolution monitor... lots of Vegas crashes and flaky dialog box behavior.
