Transcoding 50 fps Interlaced AVCHD to 50 fps Progressive x264 with MEncoder

“Have you ever wondered how much quality your HD camera can
deliver? This script helps you to find it out if you have a camera
that encodes interlaced video. It uses special filters to calculate
50 whole frames out of the half frames, which makes motions seem
extremely fluent. You could play the file at half speed slow motion
and still have a full 25 frames per second.

“You need a more or less recent version of mplayer. It should be
a version of mplayer after the release of ffmpeg 0.5. Current
repositories of current distributions should be able to deliver
this. But be aware that not all of them provide an mencoder
compiled to work properly with x264. If that’s the case you may
have to compile it yourself.

“After that it’s as “easy” as this command, once you’ve put it
all together. I’ll explain further below and post a sample script
for the entire conversion. The result is extremely smoothly playing
video files that look great.”
