Encoding NGE the Remastered Platinum Edition

I found a simple way to remove the combing. Here is my "complete" script. Code:

I want to resize to 640x480. Can I do that or should I go with 640x432?

I strongly recommend encoding anamorphic because it will produce an encode with a much higher quality than a downsized one. If you still want to resize to 640x480, replace the crop call in my script with crop(4,2,-2,-2) to keep the correct AR. (and of course, use spline36resize(640,480) instead of 720x480)

At the end, the credits sort of "crawl". How do I fix this? In other words, they drag/lag.
