Well I did a forum search and I hadn't seen this posted prior. I was having difficulty putting the PS3 Tech Demo as my "opening.avi." I would always get those two soldiers floating in mid-air and the music would begin to play prematurely. I noticed my PS1 movie I had converted before had a set frame rate of 15fps. It was a quick fix with VirtualDub.
First select Video=>Frame Rate...
Next go down to the Frame Rate Conversion, select "Convert to fps:" and put 15.0 in the text box. (If you used the Source Rate Adjust that will screw up the video audio syncing)
Select Video=>Color Depth...
Change to 16bit
Don't forget to resize any .avi file to 320x224, easy to do with the appropriately named "resize" filter.
I used the .mov file from ign.com. You can also remove the ign icon. I used the "logo (1.7b2)" filter by Donald Graft. I just made a black .bmp to cover it up.
Finally, I did some miscellaneous tweaking like post-processing and sharpen filters.
One advantage I found was that the new video could be as long as I wanted. My new intro is only 1min 30sec, while the original was 1min 59sec and there wasn't any problems.
Unfortunately I couldn't remove the "tech demo for ps3" logo yet. Thinking of just overlapping it with a different logo. How does "Ultimate Qhimm Edition" sound?
If this has already been covered than sorry, just figured this could be useful to someone out there.
