    Pixelated Box Effect, How to do it?

      I used virtual dub to make a video as small as possible, like 50x50 pixels. Then when I open it, of course the video is small, but good quality. I want to get a pixelating box effect, so I just opened it using full screen on my laptop then I get it. The effect is there, but not the default windows size is not. Now I was wondering if there is a method of the video opening at a 500x500 (enlarged) with the video pixelating effect which you get from manually enlarging the player window by default?
      I have tried manually making it 50x50 pixels, then using WMM & Premiere to set the pixels to 500x500 so that when I open the video file it does open to the screen size I want, but the video does not turn out boxy like I want. Vd, WMM, Premiere Pro CS3 all go and "smooth" out the boxed effect for me. I am trying to recreate a scene with box effect. How to go about it?

      I am not sure if I have explained it well, but there it goes
      Thank you for your help

          Have you tried applying an effect in Premiere to create the pixelation?

          Mosaic with a fairly-high block count might work for you. Perhaps also with a blur.

          Another way is, much as you mention, to put the source clip in Sequence 1 and scale it down to, say, 10%. Then place Sequence 1 inside Sequence 2 and scale it back up again. That will have the effect of pixelating and blurring that you seem to want.

            There is a problem with that. I have not tried mosaic, as I want the pixelation to be natural, not some kind of permanent square boxes on the footage. I will be doing an video enlargement of different pixels, having a boxed effect is not what you see in normal poor quality video.
            I tried the second way, but CS3 does not allow me to enlarge it by more than 200% of the original size. a 50x50pixels will only get at best is 100x100pixels. Thats what made me move onto WMM in the first place. There is a big black frame around the video where the areas which you could not get the original footage bigger than that 200%. I have tried with different video resolutions, seems that the 200% resizing is a software limitation.
            I know the idea of the limitation is I would not get any kind of "viewable" video, but thats what exactly I want. Also even though it appears pixelated during editing, after rendering, CS3 still "smooths" out the box effect for me.

              Well, on my PC/CS3 system I can get up to 600% scale increase and it does an excellent job of pixel blurring from a 20% image up by 500% in Sequence 2.

              If the maximum available from one pass isn't enough for you, just nest the process another time - ie scale down Sequence 2 in Sequence 3 and then back up in Sequence 4.
