To make fully fledged dvd's I came to use
qdvdauthor after some amount
of research. It's somewhat clunky (Mostly wrt to what it puts where
and why, tmp dirs, importing stuff etc.) but it actually does
everything related to dvd-authoring (Menu navigation, background
images/videos/sound etc.). In the end it gives you a VIDEO_TS that
you can write to a silver platter.
Please don't hesitate to ask if the unlikely need for some
hand-holding through the process should come up.
I decided on this approach:
Convert AVI to DV with Kino
Export DV to MPEG2 via Kino
Create DVD with DVDStyler
It works nicely, but... The quality of the resulting DVD is certainly
poor compared to the original.
If you can produce dvd conformant scaling and
framerate in AVS with
good quality then that would be preferrable to any later adjustments.
I believe I can do both. I can set FPS (default 30) and I can set the
video width & height. I can also specify the audio sampling rate, which
I assume should be 48 kHz for a DVD.
You can use "ffmpeg -i video.file -target
ntsc-dvd video.mpg" to
up/downscale and "adjust" framerate. This invovlves fairly good
quality size scaling and simply dropping/duplicating frames wrt
framerate.
(To actually interpolate frames you could try yuvmotionfps. I've used
it with very acceptable results to convert 30fps material from a
canon a710. Whereas the ffmpeg dropframe conversion makes high-motion
pans look unbearable the yuvmotionfps interpolation looks very ok on
a tv set. http://jcornet.free.fr/linux/yuvmotionfps.html)
I'll check it out,
thanks for the tips. :)
