I have text that I created in after effects and it looks fine and crisp in preview, but once I render out a .mov file, the text looks softer and a little blurry. I checked to make sure my settings were set to Full and Best quality but I still seem to be getting this problem. Is there something I am doing wrong?
What are your output settings (codec, pixel dimensions, etc.)?
Very likely, you're using a compressed output format, and with compression comes quality loss. It also may be that you're creating an output movie with smaller dimensions (fewer pixels wide and tall), which means less detail.
More information about ouptut settings here and on the pages that it points to:
My pixel dimensions are 900 x 800 and I am using Square Pixels for the Pixel Aspect Ratio. The video codec is set to Animation. Thanks for the link, that is really helpful to have.
