I just finished a spot in HD and I want to do a SD downconvert in Smoke. So I use the resize and I have a couple of questions on my options. I am starting with a 1920x1080 clip and setting my destination to be 720x486 with a pixel aspect ratio of 1.48. What should my filter be set at (i.e. lanczos, impulse, bicubic)? Precision? Crisp/Soft?
