Field
In an interlaced video a field is 1/2 of a complete picture (Frame) consisting of the even or odd scanlines in the frame. Usually each field is labeled ie. Field A and Field B. When working with interlaced video it is important to note the Field Order (if Field A comes before Field B in the video stream) especially when encoding. If you notice flicker after encoding you will want to change the field order in the encoding template and reencode.  



FPS
Frames per second. A measure of the rate at which pictures are shown for a motion video image. In NTSC and PAL video, each frame is made up of two interlaced fields.



Frame
Television:
A set of scanlines in video to make a complete picture. If the video is interlaced the frame consists of both of the interlaced fields (half frames). If the video is progressive the the frame is made up of one continuous scan from top to bottom. The number of scanlines vary in a frame depending on the TV system used. PAL50 uses 625 scan lines, NTSC60 (US) 525.

Video Encoding:
A frame is one picture but depending on the encoding scheme it may not be a complete picture (I-Frame) but dependent on frames before or after the current frame (P-Frame, B-Frame).
