Some sample steps here would be useful and worth having for simple 
testing ;)

And, one needs to load a 10-bit video file (fx prores, cfhd or other) to 
be able to render a 10-bit output?

Which 10-bit/12-bit output formats are currently supported in CinGG or 
potential actual to add support for with profiles etc. ?
-----------------

I looked into which pixel formats current ffmpeg-7 encoders in question 
do support as follows:

Cineform
ffmpeg -hide_banner -h encoder=cfhd | grep Supported
     Supported pixel formats: yuv422p10le gbrp12le gbrap12le

Prores
ffmpeg -hide_banner -h encoder=cfhd | grep Supported
     Supported pixel formats: yuv422p10le gbrp12le gbrap12le

x264
ffmpeg -hide_banner -h encoder=libx264 | grep Supported
     Supported pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p 
yuvj444p nv12 nv16 nv21 yuv420p10le yuv422p10le yuv444p10le nv20le gray 
gray10le

x265
ffmpeg -hide_banner -h encoder=libx265 | grep Supported
     Supported pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p 
yuvj444p gbrp yuv420p10le yuv422p10le yuv444p10le gbrp10le yuv420p12le 
yuv422p12le yuv444p12le gbrp12le gray gray10le gray12le

AV1
ffmpeg -hide_banner -h encoder=libsvtav1 | grep Supported
     Supported pixel formats: yuv420p yuv420p10le

ffmpeg -hide_banner -h encoder=av1_nvenc | grep Supported
     Supported hardware devices: cuda cuda
     Supported pixel formats: yuv420p nv12 p010le yuv444p p016le 
yuv444p16le bgr0 bgra rgb0 rgba x2rgb10le x2bgr10le gbrp gbrp16le cuda

ffmpeg -hide_banner -h encoder=av1_qsv | grep Supported
     Supported hardware devices: qsv qsv qsv
     Supported pixel formats: nv12 p010le qsv

ffmpeg -hide_banner -h encoder=av1_vaapi | grep Supported
     Supported hardware devices: vaapi
     Supported pixel formats: vaapi
