How to optimize the system and the process to get a shorter render time?
I have recently been editing videos more regularly with Hitfilm. Previously my processor seemed to limit rendering, so I bought a better one. My current specs:
AMD Ryzen 9 3900X | 2x 8 GB 2133 MHz DDR4 | NVIDIA GTX 960 4GB | Samsung 970 Evo Plus | using HitFilm 16
The rendering is already much faster, but since the processor is only at about 30% load, there must be a way to speed up the rendering even more. But I can't estimate due to lack of experience what I can change next, or easiest (on my workflow or on the hardware) to get a shorter render time.
I mostly just render MP4 videos (MPEG-4; AVC; variable frame rate) cut together in the editor without adding any effects. (Maybe just a video or audio fade). There I am aware that this is not the most ideal either.
During rendering I get the following load:
RAM: 11-14 GB of 15.9 GB,
GPU 25-45%; 25% in 3D, 40% in Video Decode, 3.7 GB of 4 GB dedicated VRAM
So do I need a graphics card with more VRAM? Does the RAM already limit with capacity and/or speed? Or are there other ways to optimize the process without buying new hardware?
