What is hardware encoding?
Also called: GPU encoding, NVENC, Quick Sync
Definition
Hardware encoding compresses video using a dedicated encoder chip in the graphics card instead of the main processor.
It is many times faster than encoding in software and leaves the processor free, which matters both while recording and when exporting long or high-resolution videos. Nearly every graphics card from recent years has an H.264 encoder.
