To compress my Columbo DVDs from MKV to MP4, I don’t use a GPU — I’m capped at 100 FPS instead of 500 with a GTX 970 — but I prefer not to overload my workstation and instead offload tasks to the cloud. I use a CAX41 Hetzner VPS with an ARM processor (16 vCPUs, 32GB RAM). It takes about 8 hours to process 60 episodes. (5h with GTX 970)
