You will waste many bits if you go from 60 fields per second to 60
frames per second before encoding. You would be compressing generated
bits, since it's essentially upscaling. yadif is a very good (but slow)
deinterlacer and you will get good results with it going from 60 fields
to 30 frames per second. If you want really want to avoid going to 30
frames per second, you're better off compressing interlaced and using
yadif during playback. x264 is not optimized for handling interlaced
content, but it's still more efficient than doing 60p.
