The problem with converting ffmpeg

[Jamaika]

I would like to get rid of the message and don't know if this is possible?
FFmpeg.exe ... -f yuv4mpegpipe -strict -1 -pix_fmt yuv422p10le | x264-10bit.exe ...
[yuv4mpegpipe @ 00000000065f04c0] Encoder did not produce proper pts, making some up.
The problem is that not all of programs want to read the codec X264.
When I use the command rawvideo is fine. There are only loss of quality for converting RGB.
FFmpeg.exe ... -f rawvideo -pix_fmt yuv422p10le | x264-10bit.exe ...

How did you try to solve your problem till now?

I know this is a small problem. However, it was suggested to me that YUV conversion by the container rawideo is unprofessional. So out of curiosity I ask how it is done for the X264 / X265 / VPX / other?

Edit: I tested last codecs Intel H264 i422 10bit and HEVC i420 8bit in Magix Movie Edit Pro 2016. They don't tolerate convert to yuv4mpegpipe.
