Comp Settings with AE
 

Ive been having some trouble with after effects and the comp settings. Ive been shooting footage with the cannon a1 in dv mode, 24f 16:9. Im trying to do some color correction, but when i import the footage into after effects, and put it in a comp it looks like its in the wrong aspect ratio, the picture looks pixated and it says its running at 29.97, instead of 23.976. whats going on? can i fix this ?

Thanks
