The horizon in the photograph is on the horizontal line dividing the lower third of the photo from the upper two-thirds. The tree is at the intersection of two lines, sometimes called a power point [1] or a crash point. [2] The rule of thirds is a rule of thumb for composing visual art such as designs, films, paintings, and photographs. [3]
A fundamental property of B-frames is that they can be dropped without affecting the correct decoding of other frames. D frame (DC direct coded picture) – serves as a fast-access representation of a frame for loss robustness or fast-forward. D frames are only used in MPEG-1 video. An I frame indicates the beginning of a GOP.
Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame (intra-coded picture) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame. For example, in a scene where a car moves across a stationary background, only the ...
Normally, two fields comprise one video frame, in what is known as 2:1 interlacing. 3:1, 4:1 and 5:1 interlacing also exist. [ 1 ] [ 2 ] When the fields are displayed on a video monitor they are " interlaced " so that the content of one field will be used on all of the odd-numbered lines on the screen, and the other field will be displayed on ...
The latest overall length of both styles is the same: in 35mm, 16 feet and 4 frames or 260 frames. The countdown section begins with a single frame bearing the words "Picture Start." The sync beep (or 2-pop) occurs in synchronization with the last numbered frame ("3" on the Academy leader, "2" on the SMPTE Television leader). The length of the ...
Reference frames are frames of a compressed video that are used to define future frames. As such, they are only used in inter-frame compression techniques. In older video encoding standards, such as MPEG-2, only one reference frame – the previous frame – was used for P-frames. Two reference frames (one past and one future) were used for B ...

The term "2:3" comes from the pattern for producing fields in the new video frames. The pattern of 2-3 is an abbreviation of the actual pattern of 2-3-2-3, which indicates that the first film frame is used in 2 fields, the second film frame is used in 3 fields, the third film frame is used in 2 fields, and the fourth film frame is used in 3 ...
