I've never done any video editing before. I want to upload a video to youtube I just shot with my new pocket camcorder, but it's 7 seconds over Youtube's 10 minute limit. I just need to cut the last 10 seconds of. I'm using Ubuntu 8.04. I installed Kino, can't get it to open the file. I installed KDenlive, but I can't figure it out. I installed MJPEG Tools but I can't figure out how to even start the program and I don't see it in any menu. Yeah, I know I'm a pathetic noob. I could use some help.
Properties for the file are...
Video
Dimensions: 640 x 480
Codec: Motion JPEG
Framerate: 30 frames per second
Bitrate: N/A
Audio
Codec: Mu-law audio
Channels: Mono
Sample Rate: 12500 Hz
Bitrate: N/A

Adam, thanks a bunch. That did the trick, 1,2,3. I really have to start learning how to do stuff from the command line. That was so quick, and in cases like this, so much easier.
For anyone interested, here's that vid of some local news I caught last night as soon as I walked out the door.

We're having a heat wave in NYC. It was 90 and humid last night. It's 95 going up to 100 today. Last night some wires and transformers burned under the street. The power went out for a few blocks of apartment buildings. Luckily my building kept power. I videoed the scene in front of my building.

I have never been able to do Jack with kdenlive without it crashing. I almost always use avidemux. It's gui based, easy to use. My secondary is mencoder..

I tried avidemux also. I get this error.
No audio decoder found for this file
Save (A+V) will generate bad AVI. Save audio will work.
I clicked ok and it opened the video in the editor, but when I did the edit and saved it I got a corrupted file that loses the sound about half way through. But mencoder worked perfectly.

Cinelerra man, just do cinelerra, is easy and straighforward. I do so many videos like that and they look awesome.

Cinelerra was actually the first program I thought of. First thing I tried was...
Open Synaptic
Search for "Cinelerra"
Results in Ubuntu 7.10 = zero, zip, nada, nothing
I thought I must have misspelled it, but no.
