Hi.
This is mostly down to how your NLE handles the decoding of the H.264 codec. Different NLEs will use either the CPU or GPU or a combination to decode the codec. You probably also need to make sure that your specific NLE is set to use whatever decoding method it uses to decode the codec and that you are using specific drivers if that’s the case. As a for instance. I use Edius and it uses QSV from the Intel CPU to decode the H.264 codec but it will only work with specific drivers for the iGPU.
Even a fairly powerful CPU may have issues decoding if it’s all done in software. This is why Intel CPUs are usually a good thing, if the NLE utilises it’s iGPU for QSV. Although you’ve got a very powerful GPU, some NLEs don’t use the GPU for decoding and only use it for render assistance of FX etc. and also for final output encoding.
Also. Editing in 8 Bit can help as well as the files are only 8 Bit anyway. Using a 10 Bit project will put extra strain on a system and unless your NLE utilises dithering, there’s no need to edit 10 Bit with 8 Bit sources as it takes more processing power to do so.
You could also try monitoring in a lower resolution, for instance 1080, then switch to UHD for your final output render.
Cheers,
Dave. |
