1050×576 to 720x576px conversion results in awful quality
Hi.
I have created footage in After Effects that is 1050 x 576px, Square pixels.
I need to burn this to PAL DVD so want to convert it to 720 x 576 at 1.46 ratio.
I dd this by creating a new comp that is 720 x576 at 1.46 ratio. Then putting my 1050 wide footage within it.
When I go on to render this out, the quality becomes awful and everything is blurred. Even set to Animation 100%.
What is the best way to convert square pixel footage to Pal without any quality loss?!
thanks in advance.

Upload a screenshot of Render Settings and Output Module settings. It would help to solve the issue.

When you change your aspect ratio (PAR), the pixels change shape. This can create a blur, stretch or other problems when you are starting with square pixels and then changing them. Also remember you are downconverting. What you want to do first is downconvert to a squarepixel variant of the resolution. The pixels are rectangular in a 1.46 par. So your height would be 1, your width would be 1.46. Multiply 720 by 1.46. That’s 1052. So now you are 1052×576. You see? Your Par didn’t convert down, you blew it up in an odd way. You want to convert to a new PAR, find out the exact size of your video at a specific par. 1050\1.46 is just over 719… …You want to use the 719 value, not 720. You’ll need a custom size. Now, set up a sequence for 719×576, place your video. Set up another sequence for 720 if you want, and place the 719 into it, then scale to frame size. You won’t have any more problem.
