In this video, we're going to have a look at enabling GPU rendering by entering custom rendering parameters. Note that GPU rendering is experimental. You may experience crashes, etc.

Here are the available GPU Rendering Parameters:
Nvidia – NVENC – H264 – Constant Bit Rate
f=mp4 vcodec=nvenc_h264 vb=30000k rc=cbr acodec=aac ab=192k

Nvidia – NVENC – H264 – Variable Bit Rate
f=mp4 vcodec=nvenc_h264 vb=30000k minrate=20000k maxrate=60000k acodec=aac ab=192k

Nvidia – NVENC – H265 – Constant Bit Rate
f=mp4 vcodec=hevc_nvenc vb=30000k acodec=aac ab=192k

VAAPI – Intel – H264
f=mp4 vaapi_device=/dev/dri/renderD128 vf=’format=nv12,hwupload’ vcodec=h264_vaapi
vb=30000k acodec=aac ab=192k

VAAPI – AMD – H264
f=mp4 hwaccel=vaapi hwaccel_device=renderD129 hwaccel_output_format=vaapi
vcodec=h264_vaapi vb=30000k acodec=aac ab=192k

My setup:
OS - Pop OS 20.04
Kdenlive - 20.08.2
CPU - Intel i7-3770
GPU - Nvidia 1050 TI (Low Profile)
