Hi folks
I have a bunch of jpegs, 41000 of them. Basically I
was using the cinelerra
to do the video editing. When I rendered the final
project as an mpeg the
mplex was complaining bitterly. Basically mplex was
complaining that bit
rate was too low and also dvdauthor was not pleased.
In the end when I put
the thing on dvd, mplayer seem able to play with sound
but standalone
dvdplayer doesnot like it.
Hence I rendered the images to jpeg shots from
cinelerra. I thought it would
be a matter of using mjpegtools and just create the
necessary mpeg2 video
file from it, then mplex the mp3 or mp2 whatever. But
no, it does not work
that way.
I used the command as below
#find . -name='*.jpg' | sort | xargs -n1 jpegtopnm |
ppmtoy4m | mpeg2enc -f 8 -b 14000 -s -n p -F 3 -a 2 -c
-B 3000 -o final.mpeg
but with -b ranging from 8000 to 40000 and -B ranging
from 300 to 3000. No
matter what I do mplex does not like it and complain
that bit rate too low.
Also dvdauthor helpfully advises me to remux the input
:-)
Is there anyone who can tell me what I need to do to
make a mpeg2 stream out of
the 41000 jpegs and mplex it with equal time length
audio in mp3 or mp2
format to put it on disk and play on stand alone dvd
player!!

Trying with rate below 26000 seem to complain as
above. But with
#mplex -f 8 -r 26000 -o final.mpeg final.m2v final.mp2
what happens is below.

**ERROR: [mplex] Need to split output but there
appears to be no %d in the filename pattern final.mpeg
When I tried with %d in command line filename, for a
27 min video it creates 8 mpegs which I tried with
dvdauthor which complains that it can't find VOBUs
and bails out.
Any help would be gratefully accepted.
I am considering installing win2k just for using roxio
videowave or magix
media edit pro. Yes. I am that desparate, but I just
hope it can be done
with out resorting to windows, especially since I
wiped it more than a good
few months ago and not keen to go back.
Thanks
