Since I have started making the EmuMovies HiQ sets I finally decided to tackle M.A.M.E. for a few reasons.
#1 Many into sequences do not have sound. I load the game, manually record the intro then if needed will actually record some gameplay.
#2 Because I run multiple emulators and have captured previews using a standard resolution, I use the stretch option in the front end to fill the preview box. In mame this really jacks up the vertical games. So I am making all of my captures full screen at 640x480 and on the verticals it includes the black bars (or cropped bezels)
#3 I really like the higher quality vids for full screen screensaver mode. There is virtually no difference between the preview and the game itself.
Now I will say that it is WAYYY more time consuming, because I have to take the raw capture, edit and crop it in premeire elements, export it, then do a batch convert to xvid every 50 or so previews. I also can not make videos for games that are basically not playable anyway framerate wise. But I just finished building a new system to tackle this and so far I am through #-A and have had no framerate issues.
I slapped together a new Core 2 Duo setup clocked at 3.0Ghz per core, 8800 Nvidia GTS video card, and two gigs of ddr2 800 memory. I also got my hands on a new 750GB "Work Drive" to handle all of the raw captures and emulation files.
I will start a new thread when I get the WIP torrent up and running in the next couple of days. It will also include all of the added previews since v106.
Warning: It is going to be big, I estimate the entire MAME preview set to clock in at about 14GB when finished, so many folks will probably be just fine with CD Browns work.
Edit: could use some help with a small compatability snag, if anyone could test for me go here:
