I've read that this should usually be used unless its high action video and then more I frames may be introduced than necessary, I've noticed in your templates that detect scene change isn't checked, what is the reasoning for this?

When encoding from a divx I occasionly get parts of the image in the next scene until theres motion on every part of the screen.

TMPEG always inserts a new I frame every time it detects a new scene change with this setting disabled, but I've seen it insert I frames in some spots after analyzing with bit rate viewer where they weren't needed when this option is enabled. That makes larger file sizes. That's why I disabled it in all the templates. Maybe it works better selecting it for DivX material, but that's was not the the purpose of the templates. They were created for high quality sources, such as original MPEG-1,2 backups and encoding from AVI ( compressed or uncompressed ) captures.
