[FFmpeg-user] how transcode ProRes to Quicktime?

I've got an Apple ProRes clip I'm trying to convert with Quicktime
input file :
Stream #0:0(eng): Video: prores (apch / 0x68637061), yuv422p10le,
1920x1080, 169867 kb/s, 23.97 fps, 23.98 tbr, 2997 tbn, 2997 tbc
I originally tried:
ffmpeg -i original.mov -an -vcodec libx264 -tune film -crf 29 -vf
hqdn3d=4 -threads 0 output.mov
which worked, but didn't play in Windows Qt 7.7.2.
googling led me to believe qt doesn't play high profile, so I tried
setting profile main:
ffmpeg -i original.mov -an -vcodec libx264 -profile:v main -preset
slower -tune film -crf 29 -vf hqdn3d=4 -threads 0 output.mov
But that didn't work:
x264 [error]: main profile doesn't support 4:2:2
[libx264 @ 0x157ac20] Error setting profile main.
Following a March 23 post in x264-dev I added this to the original the
-weightp 0 -b-pyramid strict
that worked, but wouldn't play in qt!
x264 0.125.2200+38 f417de2
ffmpeg version N-40958-gea5dab5
built on May 22 2012
Any help appreciated.
