I sent this message a couple times with zero response. Is there anyone that
can help with using NVDEC for decoding, converting 8bit to 10bit on the
GPU, then using NVENC to encode the video?

If I understand correctly, you want to first convert to 10 bit and then

I am trying to keep the transcode completely on the GPU using CUDA to
decode then NVENC to encode, avoiding sending the data to the cpu and back
