introduction / problem with video files

[Boris <boris@cation.de>]

Hej listmembers,


I'm new to this list and want to introduce myself: My name is Boris from
Germany. I've been using debian since woody was testing and think to be
quite familiar with some basic technics, server related stuff like
samba, apache, mailserver..... Also, I use Debian on my desktop since
years - with all prices one have to pay for that.
Actually, it's the right time to give a full hand of applause to all of
that people who make Debian work like it does! Thank You!

Well, now here is my actual frontier:
I bought a digital video camcorder and have big troubles with the
produced file format. It's a Toshiba Gigashot K80HE. It seems to be
http://www.heise.de/newsticker/classic/quite exotic, even the Toshiba
website doesn't seem to know it well. But it works well and produces
nice 720p videos (1280x720 pixel) that can be output directly from cam
to beamer with that resolution.

Now I want to process the files on my desktop PC and cut and author and
put new sound under it and so on.
Having the files (gsc_123.mp4) copied to the computer, totem plays them
with lousy bucking, the duration mark jumps forth and back. Also, the
resolution is not recognized, so totem opens with 720x480 what is the
resolution transcode seems to find out from the file (see below). The
output from transcode is only video noise.
Looking at the Audio/Video properties from the file dialogue in gnome,
the resolution 1280x720 is found, but no codec is diagnosed.

The software that came bundled with the cam (PIXELA ImageMixer and NERO
Essentials) is for Windows of course and I didn't have a chance to try
it out due to it's needing of DirectX that isn't available in
VirtualBox, where my last Windows resides.

So the question is: How to handle? How can I analyze the files and find
out how to bring it to DV ?

Thanks very much for you ideas!

Boris
