hi
Thanks for this suggestion! But a few questions:

Why did you leave out -o ? For example, why not:
ffmpeg -i flie.ogg -o file.mpg?
Becouse thats how ffmpeg works.
Also, someone else suggested that I do this:
ffmpeg -i mansour.ogg -target pal-dvd mansour.mpg
This will give full frame DVD. The source is though normally not a full
frame.
Consider.
ffmpeg -i file.ogg -target pal-dvd -s 352x288 file.mpg
ffmpeg -i file.ogg -target pal-dvd -s 352x576 -aspect 16:9 file.mpg
Remember that the ITU-Rec 601 spesifies that the viewable screen is 702
px wide. So the 4:3 og 16:9 is on pal 702x576. Consider therefor croping
the source on the side, if there are black lines. This will give you
better compression.
ffmpeg -i file.ogg -target pal-dvd -cropleft 8 -cropright 8 -s 704x576
-qmin 6 file.mpg
ffmpeg -i file.ogg -target ntsc-dvd -cropleft 8 -cropright 8 -s 704x480
-qmin 6 file.mpg
The qmin prevents unnecessary runaway bandwidth usage. (goes in to VBR
when q=6, prevents padding, 6 is a LOW number)
Again, I am noticing that there is no -o here. Why is that? Also, I
am in the US, and I am primarily interested in distributing this film
via the Internet Archive and YouTube. I guess that we could re-render
for PAL and NTSC later.
You should render what the source is closest to. If it's from a NTSC
source (eg 320x240,15fps), use NTSC.
Thanks again everyone for the suggestions!
