Video Sampler

This is a product that I would really like to see developed. A video sampler. you could capture clips from different sources. movies, TV, DVD, whatever... And loop the samples to run endlessly, then add other clips and specify transitions or distortion effects on the fly. The device would be all digital and centered around a DSP chip. The device would be approximately 12" x 12" wide and 3" tall, with the face of the device sloped so it would be convenient to use while sitting at a desk. It would have a large hard drive, like 20-50GB's to store the video clips and to save production data. Think ultimate video portable production capability. The device would have a 9" LCD screen split into three areas. First you would have a portion of the screen that would show what the device was outputting, that is the current video being shown, if you were to add any transitions, blend with another clip or alter the video being shown in any other way it would show up here. Then there would be a preview section, this would be used to preview other video clips before they are added into the mix, also when you sample clips from a source, the video input you are sampling from would show up here as it is received, then you could just tap a button on the device to capture the video you want. Then there would be a third window with operating system commands, here is where you would select effects and transitions and navigate the menu structure. The third area would also have a time line where you could specify how many time to loop each clip, set up different options for playback. Additionally the device could be setup to accept MIDI commands, then you could trigger specific video clips at important moments during a performance. The device would have a pad bank, that would look like ten buttons aligned in 5 columns, 5 rows. When ever you create a sample it would be stored to one of these buttons, to play it in the preview window, simply hold the button down, to drop it into the mix, hold it down and tap a button on the device. There would be graphical menus controlled by up, down, left, right, enter buttons. there would be also a pitch controller of sorts to speed up or slow down the playback speed of the clips in real-time, either modifying the video in preview so you could alter the sample to always playback at the modified speed, or just to tweak the main display to funk it up. you could go slow mo on anything, or take it back, hit it again, like a record scratch. You could even plug in a video camera, and add real-time effects to the live image, intersplice a clip from the pad bank drop in a transition, and let the mix live on. I don't know if I have adequately explained how I envision this thing working. If anybody else knows what a Roland SP-808 is or does, it would look and function a lot like an audio sampler, only it would be processing and sequencing video. You can do all this with audio, why not video?
