high quality = not easy to playback

[Viechal]

Hey as i already said i am making gamemovies for Enemy Territory and i want to get an amazing quality.
I encode the videos with h264 as mp4.

Well everyone releases the movies in a resolution of 800*500 or similar...
The quality is basicly not bad in this resolution but i have already started to work on rendering it with 1280*800.
Well the quality was imho amazing but there still were some problems.
On lower PCs the movie got lags and thats ****.

Is there anything that i can make differenty without a suffering quality?

What i am doing: recording a scene with 120 fps in a res of 1440*900. then i stick the frames together with virtual dub and change the framerate to 30.
In Vegas I change the playback speed to 4 and then render it out with the same resolution.
Finally i encode it with my makemp4batchfile.

Is there anything that i can improve or change to make it easier to view?

Thx a lot
Mfg

h264 is a higher quality codec, which requires a higher speed decoder to decode it in real time. If you are not already using coreavc, I'd recommend that, as it has a ~40% boost in decoding performance compared to ffdshow (although it seems this will be cut to 20% soon).

Another Vote for CoreAVC

check - what do you mean by 40%-20% boost difference? Is CoreAVC getting slower or is ffdshow getting faster ?

[check]

the latter; coreavc has had no significant speed improvments over its entire lifetime, whereas ffmpeg (and therefore ffdshow) is slowly improving.

do you know is it possible that coreavc will be free in the future?
because if it would be i could release my vids with an installer of it...

Unlikely CoreAVC will ever be free. Another option is to try Instant Player, which is a version of mplayer that packages your file and player into a single .EXE

Going with 24fps or 25fps helps a bit too, smaller file, slightly less taxing. Videogames can be tough in that they are a constantly changing picture, very little static view, constant panning and whipping around.
