Uploading long, television videos to Youtube

[weareone]

Hello. I recently downloaded a 37-min video of Obama giving a speech just to see how large the file was. I was surprised to see that it was only 90 MB. This surprised me because an eight-minute video shot with my digicam (Kodak Z612, produces videos with .mov extension) at a resolution of 320 x 240 would be about 90 MB. So, in light of this, I have two questions.

(1) How did they record a CNN video? I remember that with VCRs you can't record on cable channels. What's changed.

(2) How did they make such a temporally long video file so small in terms of file size? Although the image quality isn't what I would call the best, it's still not half bad.

probably used flv with a much better source (HDV)
try looking inside your obama speech with
mediainfo
or
gspot
and see what it says
then compare the info with your mov
