<< Solved >> GPU for 4K editing

[amitkool21]

Hey, I am a video editor myself. try converting the GoPro footage to Apple prores. It will be larger files, but will run much smoother. Most CPU’s don’t like h264 or h265 directly. I have the same problem with a bit more pro build. Changing codecs will help. But also advice you to update to a 8 core CPU with 32gb of ddr. Also the editing harddrive could bottleneck your performance, try using a fast drive like a ssd or usb 3.1 external disk (if you even have those USB’s on your build).

Thanks for the input mate, the thing is 4K footages from my drone and canon mirrorless is working fine, only the gopro footage is causing problem.... maybe because of the HEVC and h.265

BTW don't have enough money to get a new CPU right now, because for that I need to get a new board also.... May be I'll do that next year... So right now I'm gonna upgrade the GPU only and I'll do the editing work on my SSD only. My board don't have USB 3.1

ok. Can imagine, it’s always a lot of money to upgrade (meaning to buy new mobo, gpu and probably ram aswell). for the hevc I would suggest trying prores Conversion for now and perhaps the new gpu will do the trick. saved me when I had to edit a complete 4K documentary on my old MacBook Pro of 2008!!

With the new DGPU the should be able to deal with the HEVC and H.265 on the DGPU for hardware encoding/decoding rather than via the IGPU. For what they are used to dealing with the DGPU upgrade will be huge.

Thanks everyone for your valuable suggestions, specially @scottkendall

Just got the Sapphire RX 580 8gb and it worked OOB.

BTW Anyone knows how to use F1 and F2 to control brightness on a desktop hack......??

AMD RX 580 8GB, AMD RX Vega 56/64, AMD Vega VII, AMD RX 5700/XT

All these cards should work for 4k Video editing with sound. However, I would say that you are bottle necked by your CPU as much as your GPU, and maybe even your memory. If your trying to edit video with an Nvida card in Mojave then no wonder you are having issues since you have no acceleration. People do not always look in the buying advice forums.

4K video playback is still not smooth with this RX 580 8GB GPU ....

Is there anything that I'm missing....??

Not sure playback should be fairly easy for even a 4xx card (last gen) how manny FPS are trying to push? Do you have the IGPU enabled? Maybe MacOS is trying to use the IGPU for encoding/decoding. Try disabling IGPU in bios and changing to Mac Pro 1,1 see if that help.

2.7K video with 120FPS and tried with IGPU disabled too... But still not working.

I tried Changing to Macpro1,1 but it showed me error

This version of Mac OS X is not supported on this platform!

So I tried iMacPro1,1 , System booted with that ,but it also didn't worked for that file.....

This is what I wanted you to use I guess I missed the "I" in iMac Pro 1,1 when typing. You can try the iMac Pro SM with the dummy kext. Maybe your CPU and memory is not enough to handle and the video card is not capable of making up the difference. I am not sure why you are having uses with play back you should be ok on the playback front.

Tried the dummy141 kext too, at first it rebooted 2 times, then it booted to desktop but the video playback is still lagging.
