Zip it good!

It’s been 9 to 15 July 2017. I don’t have anything close to a preview of Shot 3 yet – it’s been a week of lost evenings, product releases at the day job, visits from interstate and a pressing need for rest. Shot 3 and its bird/cactus japery is just going to take a while longer and that’s that.

Someone asked how I did the “zip” (smear) effect in Shot 2 and whether I used motion blur. I didn’t! It’s just extreme scaling on a few single frames.

Here’s the shot in motion (again):


And here’s stills of the smear frames where the head monk appears.

Frame 73 – monk enters

Frame 74 – monk ascends

Here’s a screengrab from Blender:

The highlighted bone is the base bone. It is quite stretched.

The X and Z scale values are both 0.142 because I built the base character much bigger than it ended up being in the final scene, so I had to scale it down. The Y scale value is 1.492, over ten times the value of X and Z. This distorts the rig considerably along the length of the base bone.

This means the character covers a lot of the screen, and in a single frame I can draw the attention of the audience to what this little purple guy is up to. It ups the cartooniness, it strengthens the staging, and as long as the zip frames are spaced so that they have obvious visual continuity (i.e. no large spatial gap from one frame to the next), it’s a lot of impact for not very much time spent.

If I’d had more time, I’d have added a frame where the monk is distorted in more of a curve to follow the contour of the ground rising up into the pyramid, but it’s fine without it. (Next time for sure!)

There can be no discussion of smears and zips and such without linking a certain Chuck Jones short which is chock full of great smear effects. Who needs motion blur?

See you next week!
