Thanks a lot Jeff and Jim for your replies.
I have been playing a little bit in AE, and i noticed a quality change if I use square pixels.
Here is my scenario:
-I have captured my files from XD cam
-When i started working in AE the size of composition was 1024 x 576.
-Cause I needed the 16:9 TV format (PAL) I have drop this big composition into new one with settings 720 x 576. (PAL D1/DV Widescreen)
And I think that this new composition is losing a lof of picture quality.
Could that be a problem and if it is, then what should I do to get a “normal” PAL 16:9 format out of the big composition.
Thanks a lot once more.
