[olug] Video production

[Eric Penne]

I finally got my firewire and usb webcam stuff working again last night
in linux after my hard drive crashed.  I am using the 2.4.4 kernel. 
Now I have 10 GB of digital video from the airshow this weekend.  I
need to convert it to a format that will have good compression and last
for awhile.  I've looked into AVI, MPG, and DivX but have been
unimpressed by the tools available in Linux for the conversion.

The best contender right now is MJPEG tools but to get an mpeg stream
from mjpeg you have to convert from dv to mjpeg to mpeg and I think I
will get too much loss that way.  AVI support in linux is sketchy at
best.  DivX is really not an option because it is so new.  
My ultimate goal is to be able to convert to a format that either
windows media player or real player or a linux player could understand.
MPG has a couple of formats including mpeg1 and mpeg 2.  DVDs use mpeg2
and VideoCDs use mpeg1.  the VideoCD route would be very compatible on
every system but I don't think it gives a very high compression.  mpeg2
can also be read on almost every system but I haven't used a windows
program yet that hasn't messed up the audio sync or used a codec for
compression that was common on other systems.  I've always had to
install the same program I compressed the video with on another system
to be able to view it.  I don't have much experience with the linux
codecs so I don't know if they will be able to go cross platform and
between OSs or not. So will somebody explain this whole standards thing
to me again?

I have looked at broadcast 2000 but it seems to make mpegs that windows
media player and real player don't play.  It also won't read in DV
format video.

Enough rambling.  I will cross post this to the OLUG and HLUG groups to
get a wider audience.  For those of you on both lists I apologize.
