DVD2SVCD: Mpeg1 version great, but mpeg2 version bad?

Doing some tests with kvcd matrice and kvcd settings on a 3 hour film.

Get a great 2 CD mpeg1 kvcd copy very nice.

With the same settings just change mpeg1 to mpeg2 the picture is positively horrid, looks like a lot of interlaced lines and block noise.

film is 29.970 fps
3hrs in total time

any suggestions would be greatly appreciated.... :lol:

Thanks in advance

Hi Frum,

That's the MPEG-1 advantage over MPEG-2 on low bit rates :wink:

Cheers Kwag,

Yes I Get that, but how have you made mpeg1 look like, dare I say it mpeg2......

When I used to encode Dead Standard VCD's using Tmpgenc they never looked like that, ok they were constant bitrate, but even so thats damned impressive.

top marks :D

could you point me in the right direction to do some reading about GOP structure and matrices? I would like to learn more.

Frum :D
