BFF=Bottom Field First.
TFF=Top Field First.

The above is extremely basic stuff. Not knowing such basics, you're at a serious disadvantage. Whether you're using the most basic of encoders or more sophisticated NLE's like Vegas or Premiere, you're at the mercy of wizards and default settings if you don't know what you're doing. You don't have to be a rocket scientist to work with video encoding, but you should at least know what fields, frames, and bitrates are. Your initial query indicates that you don't know whether your source video is interlaced, progressive, telecined, BFF, TFF, and likely you're not aware of frame sizes, aspect ratios, etc. In other words, you're asking for a complete course in video structure and processing.

I wouldn't even know where to start. Try starting here: What is interlacing?

Here are two TMPGEnc Plus guides. Both are somewhat dated, but the interface hasn't changed since 2004. Each discusses different aspects of encoding and different types of video. They have illustrations and screenshots (in the first link, click on the pictures to expand them):
Rui's Guide To TMPGEnc
Lordsmurf's early guide to TMPGENC

And here is some material on a lot of basic stuff you don't know yet: http://www.digitalfaq.com/guides/video.htm

Otherwise, you have to take what wizards and automation give you. That's the great problem with wizards: one never learns anything or understands what's happening.
