TVAI’s encoding settings are recorded in “encoders.json”, which in the case of AV1 (NVIDIA) is as follows.
"text": "AV1 (NVIDIA)",
"encoder": "-c:v av1_nvenc -preset p4 -tile-columns 2 -tile-rows 2 -pix_fmt yuv420p",
"ext": [
"mkv",
"mp4"
yuv420p = YUV 4:2:0 8bit
The pixel formats available for AV1 (NVDIA) are as follows
ffmpeg -h encoder=av1_nvenc
Encoder av1_nvenc [NVIDIA NVENC av1 encoder]:
General capabilities: dr1 delay hardware
Threading capabilities: none
Supported hardware devices: cuda cuda d3d11va d3d11va
Supported pixel formats: yuv420p nv12 p010le yuv444p p016le yuv444p16le bgr0 bgra rgb0 rgba x2rgb10le x2bgr10le gbrp gbrp16le cuda d3d11
p010le = NV12 10bit
NV12 = YUV 4:2:0
Maybe if we change the “pix_fmt yuv420p” part to “pix_fmt p010le”, it will be YUV420 10bit.
