Why is there an increase in size converting AVI-2-MPEG (VCD format)?

[sjeevan]

Hi,

I an amateur in this area. So pls ignore the stupidity in the question.

As I understand it DV AVI is the best format but also the largest (200Mb per minute of video) so it is encoded.

i used the pegaSys TMPGEncoder with the standard clock.avi found in the \winnt folder.

WHAT I did not understand why the resultant clock.mpg was 2.03 MegaBytes when the clock.avi was only 128 KiloBytes

any clues?

The clock.avi was probly compressed with MS MPEG-4 or something but i'm not sure (I doubt MS would use DivX or XviD ).

MPEG-1 (VCD) and MPEG-2 (S-VCD, DVD) is not as heavely compressed as MPEG-4 (DivX, XviD) so it results in larger file sizes but generaly better image quality (for MPEG-2 anyway).

I havent yet tinkered with DV yet so I havent a clue at all about that stuff.
