And what can i do on Windows to check these capabilities?
Btw the GPU is a Gainward 6 Gb nVidia GTX 980 Ti so i think this should
support the above formats.
Any idea why this encoding doesn't work?
$ ffmpeg -i perspective.mp4 -c:v h264_nvenc -profile:v high444p
-pixel_format yuv444p -preset default perspective_out.mp4

Conversion failed!
I've now tried it on a GTX 960 (Maxwell GM 206) and there you can encode with
yuv444p. The chip was the last of the Maxwell-series iirc and doesn't support
10-bit depth. So either they snuck it in at the very last or it's an issue with
the driver or libraries. This is with Video SDK 7.0.1 and CUDA 8.0. You can try
to update the Nvidia driver and libraries and see if this changes anything.
$ ffmpeg -i
