I’ve been researching the slitscan technique lately.  I recently received some demo tracks from my friend and his band and I’m able to choose one of them to do a music video for.  Inspired by the film “The Fourth Dimension” by Zbig Rybcynski I have been interested in using this technique for their music video.  I have done many other slitscan tests on previous days (Day 112, Day 150, Day 184, to highlight a few).


Although, in all of those previous days I was using a different slitscan technique.  This technique is actually slightly simpler to describe yet the images it produces are quite hard to describe.  Basically, in all of the slitscanned images above you are only seeing one line of resolution from the original video but you are seeing the life of that single line of resolution in time across the image.  The line of resolution that I selected to use for the slitscan was in the middle of the frame of the original video.


Being that HD video is 1920 pixels wide it takes 1920 frames for the slitscan to fill the entire frame.  That’s about a minute and thirty seconds at 24 frames per second.  The shot’s I selected to use were only about 1:30 long so I had to loop them.  That’s why you can see a hard line dividing the horizontal traffic and horizontal pocketwatch images.  That’s the looping point.


I love the way this technique looks and I’m excited to see it actually animated.  My favorite image by far is the horizontal traffic one.  I love the fact that static parts of the line of resolution end up like gradient streaks while the portion that the cars happen to drive through end up looking just like cars.


I have started to render a video of one of these to go overnight but I don’t suspect it will be done by morning.  For a single frame of a horizontal one to render it takes about 2 1/2 minutes.
