DV -> MPEG gives over exposed colors

[anders@dac.se]

I've made a amature movie with a DV cam, edited in Premiere and exported the movie from Premiere to TMPGEnc (DVD).

After i've encoded the clip into a PAL Mpeg2 i get over exposed colors,
look at the picture below, the orginal DV clip to the left and the mpeg2 to the right... look at the grass, just awfal..

i trid both CBR and VBR at 4000 kbits

Whats wrong?

check that you are not using any filters in adobe first as you render (or make sure color correction settings in tmpgenc are not checked on)

if this doesnt help:

...

in tmpgenc go to the adv setting and basic color correction ...

adjust the gamma on a scene like in your sample so that it matches (you can adjust this in adobe also as you render, but its simpler to explain in tmpgenc and works the same really) ..

also in your sample you are showing 2 fields in your sample on the right but not on the left

when i doubel click on "simple color corection" i see the movie, but the colos are perfect, so i cant adjust gamma. It's first after encode that teh gamma is screwed. About the fields.. in the left frame i let Premiere deinterlace and in the right i let TMPGenc deinterlace... TMPGenc didnt deinterlace as good as premiere.

Forogot to tell you, this only happens on sub lighted objects like the grass. If you look at the forest above the grass it looks ok...

yes -- gamma will only reduce the lighted subjects .. reduce it then less then anyway, not by much though ...

its odd though as i find tmpgenc will reduce gamma ever so slightly - not increase it when i test with a spot meter on a calabrated display..

is the field order reversed in tmpgenc when encoding ? as the de-interlace works ok ? but as you are doing - adobe does a good job of it anyway.

i've found something strange, when i play the clip in PowerDVD i get these overexposed colors, but when i run them in scenerist (the program that i've authered the DVD in) the colors look like they should. But if i make an DVD image and mount it in PowerDVD the colors loook scrwed again!!!

If i play a comercial DVD it looks great even in PowerDVD

The problem is that i cant test the DVD i've in a standalone player yet because i dont have my burner yet..
