So I've been having some issues cropping 4:3 footage to fit in a 16:9 environment as well as some oddities with some 16:9 footage in general.
I originally did this with Fullmetal Alchemist (2004) and it came out pretty well with these AVS Script Settings:
Spline36Resize(848,636)
Crop(0, 78, -0, -78)

Footage Details for FMA (2004):
Resolution: 720x480
Aspect Ratio: 4:3
However, I'm trying to replicate this with Cowboy Bebop (Series) and Pokemon (The Original Opening) and its
not coming out as well for either one:

Footage Details for Cowboy Bebop (Series):
Resolution: 720x480
Aspect Ratio: 4:3

Footage Details for Pokemon (Original Opening):
Resolution: 720x480
Aspect Ratio: 4:3
If anyone knows how I can fix this, that would be great.
Now my second question is about footage for Cowboy Bebop: The Movie, which is a 16:9 source, but has a strange border on the top and bottom that I can't seem to get rid of (every time I try cropping it, it only seems to make it worse; but thats because I don't really know what I'm doing).

Footage Details for Cowboy Bebop: The Movie:
Resolution: 720x480
Aspect Ratio: 16:9
I'm not sure if this is because it was a film so its different than regular 16:9 footage for some reason or what.
Any help to all of this would be greatly appreciated.

P.S. Sequence Settings:
Resolution: 848x480 (If you're wondering why I'm using this resolution, it was under advisement from an AMV Guide)
Pixel Aspect Ratio: Square Pixels
Fields: No Fields (Progressive Scan)
(The Sequence settings between the project using the FMA footage and this project are the same)
