Slitscan Test 001: Video

I filmed the wooden artist's model slowly rotating 360°on a tripod then import the movie into After Effects for post-processing as I noted on my previous post. Following Mr.Visnic's precise instruction, I scaled down my full HD 1080p footage to 720p, in order to reduce render time.

This  1280X720 composition is consist of  360 layers each with a 2 pixel hight mask. The top of each frame is 15 second earlier than the bottom of each frame. As seen in the video, the time and motion in is represented in the image vertically. Alas, I couldn't achieve the clean effect this time due to the fact that I failed to rotate the tripod smoothly. Additionally, I also tried to process the same video using 720 layers with a 1 pixel high mask which did succeed in creating greater distortion as observed in 3 images from my previous post, however, due to the layer amount and rendering time, my computer refused to finish up the entire footage.  

Slitscan Test 001

For this first slitscan experiment, I initially decided to create slitscan images without relying on automated process that are available, such as an After Effects plugin (Time Displacement), ImageMagik, Slit-scan Movie Maker and Slit-scan Camera for Iphone. During my first trial, I took 360 pictures of a wooden artist's model rotating 360° on a tripod, then load all the images to Photoshop as one document so I could select a 1pixel high low with Single Row Marquee Tool, mask it, create a mask for the next image down then offset the mask vertically by 1 pixel, which means, in order for me to complete one image, I had to apply the same process to each 360 photo. It goes without saying, I gave up on it by the time I reached around its 30th image.

In short, many other trials and errors after, thanks to Mr.  Charlie Visnic, I finally succeeded in processing my first slitscan images with After Effects (without using the plugin). Although it does not necessarily mean that I managed to take the high way by my own, it definitely helped me understanding the mechanism of slitscan.

Above images are the extracts from two different experiments I tried out following Mr. Visnic's instructions;

>img. 3-11 Center slitscan, traveling right to left (2-pixel each frame)
>img. 12-34 Candence slitscan, traveling up to down (2-pixel each frame)
>img.  35-37 Candence slitscan, traveling up to down (1-pixel each frame)
