Is it there something like a reference film ?
I mean, some short (5 minutes) film, with both static and moving scenes, with both dark and light scenes, saved in uncompressed form,
that we can use as source to evaluate different codecs /parameters ?
regards

AFAIK, no.
The Matrix and Saving Private Ryan are used by doom9 in his guides, so that would be some sort of reference. And i noticed that Fight Club seems also to be a popular target.

That sounds just like a trailer :D
I use the trailer from the movie "The Replacements". It's a movie about american football, and it's trailer has both fast football scenes and some slow, big closeup scenes, with some scenes in a jail (dark) and some in the stadium (bright).
But the real test is with a full movie. I use a trailer because i have very few computer power (p2-350).

OFF-TOPIC and a bit LIGHT-TOPIC ;)
(Sorry)
-> But the real test is with a full movie. I use a trailer because i have very few computer power (p2-350). (rui)
@Rui,
What a pity that some real testers lack that precious processor power! ;) Also I'm here on a Celeron 900, kicking the hell outta me for each full-encode test! (Guess some testers with dual Athlon XP's should join the testers familia ASAP ;))
kindest regards,

iago, you are the real hero here because: (i must come true here)
The p2-350 (with win95B, and in the last days with a problematic HD) is at my work, where i am most of the time. (Ah, this modern life stile keeps us at our work almost 2/3 of our existence :rolleyes: )
I have this little comp available to do this tests while i am working. ;)
At my home, where i have the least time to test (this comp at home is also used by other members of my family), i have an AMD Athlon 1,4 Ghz with win XP. So i can't complain too much. :o

lamer_de: SPR is perhaps not the best reference material, due to its intentional use of grainy source material for an 'authentic' look. Not that codecs shouldn't handle this kind of material, but it's NOT what codecs will deal with on an everyday basis. Just remember xvid in the last codec comparison.
Maurizio: I always found Mission: Impossible 2 (r2 pal) to be a good reference film when testing new codecs or features. But really, any film will do. Good reference material should ideally contain a good mixture of dark and bright scenes, high and low motion scenes. So an action movie with slow passages is a pretty good benchmark...
But ideally, find your own; It's good if a lot of people have their own reference dvds, encode them to test new software, and then report what they've found to us on the board here ;)
