Or it does't support yuv420p10? And if it doesn't, why are you using mov at all, if your target is to encode yuv420p10? > I am not able to convert these prior to encoding.

Why would you pipe to the binary, instead of using ffmpeg's integration of libx265? The only reasons I can think of is: - your ffmpeg isn't compiled with libx265; - your ffmpeg's libx265 doesn't support 10-bit video (I can only guess, because mine from Zeranoe doesn't seem to). > Is there any way that I can convert from yuv 4:2:2 10-bit to yuv 4:2:0 > 10-bit and pass to libx265 on the fly without going through inter-process > communication? Normally, you would simply use: $ ffmpeg -i inputfile -pix_fmt yuv420p10 -c:v libx265 -c:a copy outputfile ffmpeg will then tell you whether libx265 cannot handle yuv420p10.
