Hmmm. Ok, let me describe the project that inspired me to all this. (Perhaps I can learn enough to get it done one day). I would like to create an app that will allow "simple" edits on full screen video on the fly. Sequential edits initiated via the key board so a GUI would not be needed while it is running. Since video constitutes stationary images shown one right after the next, I want to be able to pick and choose individual images and chain them together to run border-less from a large database of images and also allow the edits, which would be no more complex than lighten and darkening, to carry over from one frame to the next. Since each image is slightly different than the next, I'll need to be able to manipulate at the pixel level. The resulting border-less videos will also sometimes overlap each other and slowly change in size and position on screen. Thanks. Darren Harris Staten Island, New York.

This is hardly what I would term a "simple edit". I'm not a video processing type but this ain't gonna' be a trivial app no matter what it's written in and to attack it from the ground up as an assembly-coded app is a non-starter to ever getting anything functional in any reasonable amount of time. I'd think there would already be app's that could do this in existence in the open source community which would be where I'd think you ought to start. --

Exactly - not to mention, that fast decompressing is done nowadays over Codec-Interfaces (which on Windows are DirectShow...COM-Interfaces) ... and the Video-output needs to deal with Color-Spaces efficiently (usually the faster Decoder-Outputs end up in YUV or UYVY/YUY2 Color-spaces when we talk about Video-Codecs) + the then following high performant and high-quality Stretching of such decoded Output-Buffers (+ additional Lightening/ Darkening) is then performt over DirectX or OpenGL directly in the graphics-card hardware, meaning you nead another "HighLevel"-API to address these devices over their appropriate API-Interfaces on your platform of choice. You will "go nuts", if you try all that in plain Assembler. > I'd think there would already be app's that could do this > in existence in the open source community which would > be where I'd think you ought to start. Yep - and the language of choice in most OpenSource- Projects is C (close enough to Assembler IMO), directly followed by C++. Maybe looking at the Sources of VirtualDub (just google for it), is a good start. Olaf

That's what they do down in the bayou, right? -- ..NET: It's About Trust! http://vfred.mvps.org
