[FFmpeg-user] Convert 720 50p > 576 50i PAL SD (resent)

[David McSween]

Hi, I’m an ffmpeg noob using AnotherGUi frontend. I want to convert my,

h264 720 50p video (Canon DSLR QT)

to

DVCpro 25 50i SD.



So I need to interlace the 50 frames into fields, and re-sync the audio to
25fps.



Also I wonder if there are any useful filters to reduce twitter on fields
after/before conversion?



PS. Anyone know what the shutter angle should be used for shooting 50i? I
am guessing I should originate 360deg at 50fps so that it becomes a pseudo
180deg at 25fps.


Mods, sorry for sending from alt email.
