I Have noticed that the text that I have exported from After Effects were looking jagged in windows media and Kmplayer. At first I thought it was my render settings that were making it look low quality, but then I found that when played in Quicktime the movie look high rez. only problem is that quick time is extremely laggy when I open up my movies. Why is this happening?
Huh? That's simply hardware scaling. Your movie is not being viewed at 100% size.
