You need to have working NVRAM or Emulated NVRAM. In the OC Boot Picker, select the OS you want to boot as default and then press Control + Enter on the Keyboard. This tells OC to bless that drive as the default OS to boot. If you turn OFF the Boot Picker (by setting ShowPicker=False) and...

You have not provided your OpenCore EFI. Without it, it is not possible to see what/how you have configured your laptop.

Sorry I do not understand what that means. Are you saying that after a fresh install, your system is generally slow to respond to mouse clicks, etc ? Post your PR files (see last FAQ here)

Depends. Depends on your needs and what you use the system for. I have a 200MB partition for BS with 87GB free: The used space depends on your User data and what applications you have. Example: I don't have issues with 87GB free space. But once it starts filling up, you will notice the...

Good observations. HEVC vs H.264 subject is complex. There are pro's & con's for each. Larry Jordan is well known guru in the Broadcast industry. See his article on the subject. But generally Lower bitrate should produce lower file size especially with HEVC. In your experiment you did not state...

That's because you are using iMacPro1,1 model ID and one of the functions of unfairgva boot-args is to change the board id of the system for video acceleration to that of an iMacPro1,1. If your model ID is set to iMacPro1,1, then your board id is already set and that's why encoding is works via...

The whole purpose of HEVC is produce same quality video as H.264 at the same bitrate but at almost half the file size. THat's not what we are seeing on macOS with AMD dGPU. Without professional broadcast quality monitors and appropriate test equipment it is not easy to tell the difference...

Setting "Encoder Type" to any setting should work as long as "Allow frame reordering" is not checked. HEVC Encoding only works with "Allow frame reordering" disabled and I do not know of any work around. As I said before, the file size of HEVC output is actually MUCH larger than H.264 so as...

Looks better. OK so you have a Dell Vostro 270 system. Adding boot-args -wegnoigpu has now disabled the IGPU so no need to worry about disabling it from the BIOS. But you also need to add unfairgva=5 to boot-args Try it.

Post the latest PR files after making the suggested changes. What make is the motherboard/system ? It may not have an explicit setting to switch off the IGPU and may have another setting which switches off the IGPU indirectly. What version of FCPX/Compressor are you using ?

OK. From your last PR files from #38, it looks like your iGPU was still enabled. The IOREG file clearly shows the IGPU device...that is, you have a Sandybridge HD2500 device in macOS and it has NOT been disabled. Because it has not been disabled, macOS will first try to use that for HEVC but HD...

Your results are as expected since in the Compressor settings, you did NOT UNCHECK the "Allow Frame reordering" as I had suggested. That box should have no check mark (see my screenshot in post #63 above).

Happy New Year ! What exactly did you try ? What boot-args did you try ? What Compressor settings did you try ? Like I said even with my Legacy PC with RX 460, FCPX/Compressor can Encode/Decode both H.264 & HEVC.

I leave the Shiki boot-args as I multi-boot this rig. unfairgva is required for my rig for all os's. It injects iMacPro1,1 board-id which enables encode/decode. I'm using iMac14,2 model ID. Yes I am aware HEVC is supposed to create a more compressed output but with this RX 460 Baffin card, it...

VideoProc uses VideoToolBox API's to encode/decode. FCPX & Compressor use Metal (and some proprietary API's depending on the Mac to access the T2 Chip). Lot of people make the mistake of assuming VideoProc is the ultimate test of macOS's ability to encode/decode H.264 & HEVC...but it is not...
