Problem 1 When i import some anime episodes to sony vegas. The quality becomes really bad. It has nothing
to with the video itself,because when i watch these episodes with media player,the quality is good

you can see the picture above for the bad quality
Problem 2 Sometimes when i try to mask,the picture from the preview isn't equal to the picture from the pan crop
so i can't mask well, because the part that i want to mask will appear later than i actually want
Problem 3 When i import mp4 files into sony vegas,it becomes really difficult to edit them,because the video responds slow
on my action.If i want for example want to go another time from the clip,it takes like 15 seconds,when i reached that time from the clip
and if i want to go to another time from the clip,it takes again like 15 seconds. I don't have any trouble with avi.
It's only mp4,but most of the raw clips are mp4,so i would like to know how to handle this problem.
I hope anyone can help me,
