Field - Refers to half of the data contained in a picture frame, measured in lines. Two fields are necessary for one picture frame with data stored on alternating field lines.
Viewfinder - Small view of the scene you are recording. This is normally a small LCD screen. The more pixels the viewfinder screen has, the clearer the image will be. The number of pixels in the viewfinder does not relate to how clear the picture will be recorded.
Lossless Compression - A form of compression that does not degrade the quality of the image.
High-Definition television, or HDTV - Operates with over twice as much detail as NTSC under either the 720P or 1080i scanning systems. 720P (720 progressive) uses 720 total lines scanned every 1/30 second. 1080i (1080 interlaced) uses two scanning fields of 539.5 lines each, interlaced with each other, one field recorded every 1/60 second.
Progressive Scan - Ability of the video camcorder to record all lines of an image to the tape for every frame of video. Cameras with progressive-scan CCDs read each row of pixels on the CCD sequentially when recording an image. Older models of CCDs either read a pair of rows at a time or read all even rows as one frame, then all odd rows as the next frame. Both of these older methods compromise image quality.

24P - Film's native frame rate is 24 frames per second. 24P refers to the high definition format, the "P" meaning "progressive image scanning," (in contrast to "interlaced scanning").
