Some news. The layout of this P010 format is planar luma with packed chroma (see description in the link above, i missed that earlier on). It is actually supported in ffmpeg with the flag AV_PIX_FMT_P010LE:

P010 is the 10-bit variant of NV12 (planar luma, packed chroma), using two bytes per component to store 10-bit data plus 6-bit zeroes in the LSBs.

See https://patches.libav.org/patch/60979/ and https://github.com/FFmpeg/FFmpeg/blo...ixdesc.c#L2015. There is no 12/14 bit analog of this format. So it makes sense not to use that in AviSynth.
