Im rendering out a QT Animation codec with alpha. It looks good in ram preview, it looks good rendered in QT player, but when I import it back into AE (CS4) the text looks blocky and shite, like it is in 1/2 quality settings or something (but its not). The background film that I want to lay it over is fine, it is only the rendered QT with alpha that looks bad. I have made 100s of renders with these same settings, without problems, but for the life of me I cant work this out.
Thanks in advance
Can you post a screen shot showing the problem with your whole AE UI?
Without more information, my wild guess is that you're working with rectangular pixels, and you're seeing some jaggies caused by AE's Pixel Aspect Ratio Correction [link]. As you've noted, they do look terrible in the viewer, but renders come out perfectly.
You can toggle the PAR correction button () to turn the feature on or off. It only affects the viewer, and does not affect your renders at all.
