I'm rendering at 1920x1080HD 25fps. Used the expression found on numerous threads including this one to generate whole number pixel shifts per frame.
t = time;
fr = t/thisComp.frameDuration;
x = value [0];
s = 4; //Speed in pixels per frame
[x, fr*s]
I generated the text and images in InDesign and exported as a PDF. Imported PDF into AE. Have tried a few whole number values for s including 4 and still getting judder.
Generated to H264 and Apple Pro Res codecs doesn't seem to make much difference to judder.
Here is my AE project with PDF. Here is output as H264 (40MB).
Also included a Quartz Composer file (if anybody is interested) where I created the same whole number pixel movement as AE but rendering it out in Quartz Crystal I get different judder but no better. Quartz Composer previews in real time and Quartz Crystal renders same project that took some 16min+ in AE in about 30 seconds. But no smoother output — even when applying AA and Motion Blur at render time.
Can anyone recommend a video encoder where I can down-sample say a 75 fps render to 25 fps with frame blending? Does Apple's Compressor do frame blending? What about some other app that I can get this out smoothly from. I have FCP installed but have never done a title in it either.
Since my Dell only has 60Hz at full native res (2560x1440) I set it to 1080p and selected 50Hz to see if that effected anything but it makes absolutely no difference to playback smoothness.
