mk 400x254 -> resize to 256x162
tron 480x512 -> resize to 240x256

And which is it, 255 or 256? Can someone tell that by experimentation?

Yes the video will look funny (squashed/stretched). However, it sounds like a the FE's that use them correct for this to make them look normal. The main reason for doing this seems to be that a 1:1 ratio is much easier/more effecient for a graphics card to playback as a texture. Your resizes above are not 1:1 so lose the advantage that Howard talked about. It sounds strange to me too, but I have no experience in programming textures in DirectX.

Well Minwah can just playback the movie in a box.

As a texture, it can be manipulated in 3D and such things. So you can naviagte round a 3D room full of arcade cabs, and actually see the videos playing back on the screen as you move round and walk up it - its all moving in perspective to you as you move closer etc..etc...

At least, this is the main reason I presume its used for.

The 3darcade documentation says:
I STRONGLY recommend to batchresize your marquee's and screenshots and all other artwork you plan to show inside the 3d environment to a power of 2 format. I would suggest 256x256 for screenshots and marquees. And if your graphic card can handle it 256x512 for pinball playfields. This will depending on your videocard give a nice perfomance boost while texturizing models on the fly. This is essential for good performance in cylarcade mode and with the cycling of bitmaps on the screenshot texture in fpsarcade mode.

So I guess that's good enough for me.

Silver:
Ah nice one - 256 it is......

A curiosity question: I've noticed that recently in your patch, the on-screen-fps display has been disabled. Also, it seems that throttle has been hardcoded as on. This does not make much difference, but I was just curious if there was a particular reason for these?

Sorry for being dumb but where can I get this?
