When I add a text it isn't shown well on the composition. It is pixelated and I really don't know why that happened suddenly.
Here's a picture: http://i.imgur.com/O27jcCu.png
If someone have a solution please tell me above. I really don't know what to do.
Thank you very much in advance.
You have the Composition panel zoomed in to 1600%.
Video is pixels. Check your font size. It's only 7 pixels.
You'll never be able to read that on a video. The Magnification Factor (third option on the bottom left) is just that magnification of the composition panel. At 1600% you are effectively putting a microscope on the video and looking at the individual pixels. AE BASICS: Judge your final product at 100% on a standard display and never more than 200% on a HR display)
(Note: Screenshots from a Mac Retina Display are twice as big as they would be on a standard display. That's why there is the option to fit up to 200%. On a standard display the option would be Fit up to 100%)
