I am making alot of different movies which i upload to youtube from differnt games, the approach i use is:
1) I use fraps to capture ingame footage (Full size, 50 fps) (Use ingame resoltion of 1280*1024)
2) I use premiere pro to edit the movie the way i want and add soundtracks (Use the default PAL 48khz settings on new project)
3) I then export the movie with no compression to either AVI or DV-AVI
4) I then use DivX-converter to compress the file to a suitable format before i upload it.
The problem i experience happens during the editing in premiere. Premiere for some reason crops the other part of the footage. This happenes before i export, while i edit. I.e. if i view a raw file in the left monitor it shows in full screen. If i drag the same file to the timeline and press play, so it shows in the right monitor the video is cropped, meaning the edges of the footage is gone, so i cant see the ingame minimap and controls etc...
I really hope somone is able to help me out with this one, i have been trying for a long time to figure out what is wrong.
