So do it. Search here and wiki and be amazed how difficult its to some people even install some program to pc and try to find out what settings they should put there.

thing is who really puts these on there device? I watch a movie trailer one time to see if I like a movie and only because I want to check if I like it or not, I dont tote it around to view multiple times for no reason.

That´s nice. Do I care about your habits? Nope.

Well downloading your Ironman 2 trailer now to see what it looks like and what kind of codec settings you used.

I agree on using 800px wide if you want max quality, its the native for the N900 screen. No need for 30fps though, cinima is not run @ 30fps and recoding an original source that is only 24fps to 30fps is rather barbaric and pointless, infact you may lose quality there since your not going to create any new frames just by increasing the frame rate and the interpolation between the frames could get jarred up. Even in a best case you just keep the same quality but made it harder to render and the file size larger.

Hmm. Have to check that out, but I do not remember that he encoded it 30fps. And this threads point is to find and demonstrate maximum quality. If you wan optimum size&quality then there is threads and wiki for that.

I assume you just used baseline 3.0 H264 profile? or have you found the N900 can handle some of the more advanced features of the codec?

Search here and wiki.

I did following with dark knight
-> Demux audio to wav with mplayer (binary codecs included)
--> careful here because we have to downmix 5.1 or 6.1 proprely to stereo. Have to listen carefully wav because explosions might clip.
-> Open video and external audio in avidemux 2
-> Resize with msharpen
-> Unsharpen mask to sharpen picture (because of resize)
H.264 settings from wiki.
->made mp4 file
--> goto start if result doesnt satisfy

Unfortunately i have found that kmplayer plays video files smoothly when default media player sometimes gets jerky. I do not know why because both use same engine but there is bug report already about this issue.

.edit
Ironman2 and dark knight and couple of other trailers have worked for me from first firmware trought both firmwares. I have not yet tested avatar
