After Effects quality drops?

Question

I am trying to make a animation. There is a 3D animation which is sharp, I need to put some layers over it with descriptions about some parts that are shown.The original video is extremly sharp, but when I render my own version in After Effects it isn't sharp at all. I changed the 'Interpert footage > Main' a couple of times but it doesn't help. Also in the render queue I changed the export settings, still nothing changes.I am trying to export as a QuickTime > Photo > Quality 100%. I am using AE CS5.

Answer 1

What format is the original video? It is best to bring in the original file sequence (lots of individual files). If you are using a rendered AVI or QuickTime, you end up double compressing the information and that will result in loss of quality.

Are you stuck on the QuickTime > Photo > Quality 100%? Have you tried other codecs? H.264 is a common one that is used for animation.
