Very small movie interpolation problem (16 pixel by 9 pixels)
Hi all!
I’m having a problem with creating tiny movies. I’m trying to make a 16 pixels by 9 pixels movie, with a single white pixel line moving one pixel per frame.
The problem is that whenever I render the movie, it results in the line being interpolated, sometime taking up 2 pixels with various greys.
I’m not using any compression, all the values are pixel accurate, no motion blur or frame blending or whatever options I think could be the problem…Any clues on how to get the required results?
p.s. for those wondering, I’m trying to use these movies as ‘control values’ for a matrix in Max (Jitter). That’s why I’m making tiny movies 😉

Hi.
I’ve set up a project as described.
I created a single pixel white layer, which due to its size was grey instead of white, collapsed transformation, duplicated 10 times. (to make it white) precomped. animated one line per frame. seems fine.seán

> Okay, educate me if you would, sir. I don’t see why the AE version would make a difference.
Here are some threads that go into some details about new output module constraints and how they affect very small AVI files:

For example.

Hi all,
Thanks for the replies. I’ve been doing things a little differently, so the AE solution kind of moved to the background.
To answer some of the questions: I’m using AE CS4, I’ve put a keyframe on every frame, the line moves 1 pixel every keyframe, so no interpolation happening there. To be sure I also used ‘hold’ keyframes.
Codecs: I tried several, uncompressed, animation, photoJPG, and several others, so the problem wasn’t that.
I’m making quicktime movies, not .AVI, so I don’t think the problem described on the adobe forum applies. I’ll try making a 32 pixel minimum size version anyways, just to check.
