can't transcode mpeg videos to iPod compatible .mp4 (was Re: [videoblogging] 15 min turnaround, live-event video-blogged (Treasure Island, Las Vegas)

I tried a couple of cameras which produce MPEG videos.  I wanted to get them as video-clips, as part of my NAB video-podcast over iTunes:

[ or do a search on "nab" in iTunes Music Store ]

I  can't seem to find a program to transcore the .MPG files (mpeg 2? "Get Info" just tells me "MPEG movie") to iPod compatible movies (.m4v):

1) I tried importing them into iMovie
picture is fine..NO AUDIO!

2) bought QT Pro for $29
picture is fine..NO AUDIO!


I don't understand.  I checked out QT Player preferences, & it seems as if MPEG input videos are accepted.

It happened with TWO cameras which produced .MPG videos.

I tried a 3rd device which produces a .AVI movie.  When I imported it into iMovie, it produced a video clips with NO PICTURE, but had sound!  It's reversed from the above!

Can a multimedia expert out there tell me what;s going on?  Am I doing something wrong?

I can certainoly blog the .MPG & .AVI files to my video-blog at:


..but I would prefer iPod compatible .mp4, so it can be downloaded as an iPod compatible video in iTunes.

I did some tests at the Treasure Island "Sirens of TI" show.  You can 
see the results at:

http://treasureisland-lasvegas.blogspot.com/

I was using a digital camera (w/video capability, most of them do), 
took the video, ported it to my Powerbook w/USB cable, & uploaded it 
to Blip.tv.  I got the video "blogged" within 15 min of taking it 
(video was taken ~10:15pm, uploaded it @10:30pm (for some reason the 
time on the blog-entry shows 10:00pm..?).  I then transcoded the .mpg 
to iPod compatible format.  For some reason the 1st upload to Blip.tv 
had a glitch 3/4 way into the video.  I retried it, & it was OK.  I 
then got the video to showup on iTunes "Treasure Island" video-
podcast (do a search on "treausre island" in iTunes)

Then, I hooked up my iPod.  I.,e., that 10:15pm episode @Treasure 
Island, was available to iPod owners within the hour.  I could have 
had it up as soon as 20 min, were it not for the glitches.

I plan to do some more video-blogging (15 min turnaround) @NAB tomorrow.

I need some feedback on my project.
