![]() ![]() ![]() Resizing happens when your DI workflow is based off a non-standard raster. 95% of our reports of “omg, jitter” come down to this. You received a clean render, but it was re-sized in post.This method, while common, virtually guarantees that you’ll land on a non-integer scroll speed. Your title designer simply keyframed an in- and out-point instead of specifying a scroll speed.Sub-pixel motion generally comes from two places: This yields the typical “pulsing” or “strobing” effect. That shifting pattern usually has a phase-it repeats itself every n number of frames. That’s what makes your end titles jitter. Changing those grey pixels frame-to-frame results in temporal aliasing. ![]() Sub-pixel motion is accomplished by subtly shifting the pattern of grey (actually, semi-transparent) pixels at the edges of each glyph. This means that the number of pixels your credits travel each frame is not a round integer like 3.00, but a decimal like 3.18752. Subpixel motion -> temporal aliasing -> jitter What causes it? ![]()
