    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Yes, with the exception of Final Cut X. The newest version has issues but the previous one, 10.4.6 works well. Everything else is great.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    I have your motherboard with a Radeon VII running well...it's based on Pastry Chef's golden build. He's created several EFI setups and has BIOS settings you may want to look at. Think it may help.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    I tried the recommendations in the video and ran some tests. So far, the older version of Final Cut 10.4.6 still renders considerably faster than the new one. The changes made in 10.4.8 seem to break hardware acceleration causing H265 to render painful slow and also double the render time for...

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    Updated successfully. Had a black screen issue but used agdpmod=pikera boot flag which fixed. How do I shut off the log text that appears during clover and next to the Apple logo during boot?

    Hey @pastrychef - did you upgrade to MacOS 10.15.4? Have any issues or all ok?

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Yeah for whatever reasons if I do the same my system hangs. I spent most of Saturday trying different options without much luck.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Thanks, I couldn't make acceleration work on FCPX 10.4.8 when the iGPU was enabled using Mac 1,1. Any special settings you used? Which OS are you on? I tried 19,1 as well without success. But I was also having boot freezes unless I changed the platform ID to headless while iGPU was active. And...

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Final Cut X version 10.4.8 - HEVC Hardware Acceleration Not working Final Cut X Version 10.4.6 - Working Same goes for Compressor and Motion...new versions don't have acceleration, previous versions do You can still render in the new versions, they're just painfully slow without the hardware...

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    I was able to pull a previous version of Final Cut X (10.4.6) and it works normally. HEVC is accelerated. Premiere Pro is also fine. So you're probably right...some kind of driver change.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    I'm in the same situation... HEVC acceleration not working in FCPX, Compressor, or Quicktime but is working in Premiere Pro and VideoProc. I was able to pull version 10.4.6 of FCX and can confirm it works well...HEVC acceleration is active. 10.4.8 took a minute to render 10 seconds of 4K...

    Catalina 10.15.2 Update Lost HEVC/h265 Acceleration

    So I'm seeing slow HEVC encoding issues but only with Final Cut X, Compressor, and Quicktime. Premiere Pro, Adobe Media Encoder, and VideoPro are normal. A 10 second clip in Final Cut takes about 1 minute to render. Premiere is 11 seconds. Hackintool shows VDA Decoder is fully supported. So...

    Final Cut X HEVC Export Very Slow. How about you?

    Curious about those who have Final Cut X and HEVC export working well on Catalina. What setup are you using? On my system (SMBIOS Mac 1,1 - iGPU disabled) FCX, Quicktime, and Compressor take FOREVER to export clips despite having a 9900K process and Radeon VII graphics card. A 10 second clip...

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    Updated everything. As soon as the iGPU is on, system freezes during boot. Tried deleting Whatevergreen and the system froze even sooner. Only thing that makes any difference is changing the system ID. It will then boot using 19,1 ... but very slowly. And even then, it makes no difference to...

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    Thanks. Yeah I don't get it either. My old system I could switch definitions and it never had an issue. Maybe it's whatevergreen...I'm updating everything including adding your newer EFI. I'll try it, then remove whatever green and see what happens.

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    So far I feel like I'm playing darts with the lights turned off and trying to hit a bullseye. But been tinkering and when I changed the platform ID to 3E920003 (headless), the system booted. It took much longer and I had to unplug and replug the Displayport cable but eventually worked. Trouble...

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    I've been trying to switch SMB So I'm making one more attempt at getting SMBIOS 19,1 to work on my system. The issue has been that every time the iGPU is switched on in BIOS, my system crashes/restarts. I'm using the same EFI from this post along with nearly the same hardware. My current 1,1...
