Hello.
I want to know what is the best way of converting a
movie (in avi format) to SVCD when the aspect ratio
of the movie differs from the intended SVCD aspect
ratio (4:3). For instance, converting a movie with
frame size 608x256 to SVCD with aspect ratio 4:3
NTSC.
Up to now I have been using ripmake and mencvcd.
ripmake, uses transcode to resize the input and
call the mpeg2enc export module.
mencvcd calls mplayer, which, with the help of the
expand filter, can expands (not scale) the movie
resolution to a given value and place the unscaled
original at given coordinates (default: center),
while outputing a yuv4mpeg stream which is piped
to yuvscaler. In the example above, the option
"-vf expand=:456" to mencvcd brings the movie to
the desired SVCD aspect ratio (608/456 = 4 /3).
Is there any better solution to this? Maybe using
some mjpeg tools.
PS: I have noticed that ripmake (which is based on
transcode) performs better than mencvcd. Would
it be due to mencvcd runs more programs:
mplayer -> yuvscaler -> mpeg2enc
while ripmake is based on transcode:
transcode [...] -y mpeg2enc [...]
Any comments on that?
Regards,
Romildo
