I have a 3 minute 30s movie, 30 fps, put together from clips that I captured using camtasia studio. It's 676px x 408px.
I've edited it together in premiere cs4, but I'm having issues trying to get a good balance between filesize and quality. The best I manages with quicktime was 60mb while retaining quality, the best with mpeg-2 was 122mb.
This is out of my area of expertise but those numbers seem high. I created a quicktime version that was 30mb, but the quality was terrible,
Please could anyone give me some suggestions on which codecs and settings I should be looking at to try and get the filesize down?
Reduce the framerate to 15 fps and see if that is sufficient. You can also try WMV.
I find H.264 to give me the best quality with the smallest file. But there's really no magic formula here. Trial and error is the name of the game when it comes to specific settings.
