The Altered State Gif Technique
Just for you Michael…But also for me: take a look at this gif. Awesome.
So, now for instructions. It started with this Tweet:
@mdvfunes find a fast cut bit of video 6-12sec. Throw-out as many frames as secs. Crop to liking. Save w/o dither. Only 12-16 colors. Crazy.— Michael B Smith (@mbransons)
Here are the instructions that produced this lovely gif.
- Find a fast cut bit of video 6-12sec – This was referring to a piece of footage in which there are number of cuts in a short period of time. The most famous example of this of all time is definitely the shower scene from Psycho. There’s probably 50 some cuts in a two minute scene. That’s rough a cut every two seconds.
- Throw-out as many frames as secs – I’ve come to a rule of sorts with the maximum number of frames in a single GIF given it seems to work with Tumblr which has some often perplexing GIF rules. The file has to be less than 1MB and 500 pixels wide. But at times the GIF meeting those two requirements still gets rejected. At times by tossing out frames and hovering around under 30 frames in the GIF seems to do the trick. So with film/video being a medium that is 24 to 30 frames per second, I will throw out a corresponding number of frames based on the number of seconds long the video clip is. So for a one second video, I would use all the frames. Two seconds, I would use every other frame. For a six second clip I would use one in every six frames. Photoshop has this option while importing video to layers. I’m not sure if GIMP does this.
- Crop to liking – This is for Tumblr rules and aesthetic ones as well. Particularly if the original video is HD resolution or higher, sometimes focusing on an area of the frame rather than the entire frame is more interesting to me.
- Save w/o dither – Dithering is a form of digital noise added to the image to try and smooth the visual transition in color gradients. Think of a sunset’s reds to oranges to yellows. Without a dither, the transitions between colors can be very blocky/pixelated. Also without dithers, the size of the GIF tends to be smaller as there is fewer changes in pixel color assignments between frames.
- Only 12-16 colors – GIFs have a maximum color palette of 256 colors, which if you think about how good the image/animation can look it’s amazing. By intentionally reducing the color palette to a few colors, the image becomes ‘posterized.’ And for the same reason as no dither, the file size is typically smaller.
- Crazy – because the results were surprising and visually interesting. I really liked the even faster cutting of the image and the limited palette that holds it together.
It is so simple when you have good directions. These remind me of glitch art and I have learnt something about the aesthetics of choosing a gif moment. It is all in those instructions, read carefully.
Here is to you Michael, thank you.
