Different issue, but as you are using 422 if you ever want to make a dvd
or something that needs 420 you will need to be very careful to make
sure you do an interlaced aware conversion.
Historically at least there are potential issues with this.
IIRC it just won't(didn't) work if you use
ffmpeg ..... -target pal-dvd -flags +ilme+ildct ... as a scaler gets
auto inserted and does a progressive conversion even if you try to
This may not apply now - or there may have always been a way I didn't
find. (what I did was avoid using target of course, but that meant
working out the other params the target set).
