Is it possible to transcode ProRes 4444 XQ into H264?

[in...@opsomai.com]

Hi,

Someone sent me a 4444 XQ MOV that I have to transcode into MP4 / H264, but my usual parameters don't work. The pixel format conversion from 444 to 420 seems to fail:

ffmbc-0.7.4 -i Jingle_tag_sticker.mov -f mov -vcodec libx264 -pix_fmt yuv420p -an -y Jingle_tag_sticker2.mov

FFmbc version 0.7.4
