  2. Frame rate - Wikipedia

    en.wikipedia.org/wiki/Frame_rate

    Frame rate, most commonly expressed in frame/s, frames per second or FPS, is typically the frequency (rate) at which consecutive images are captured or displayed. This definition applies to film and video cameras , computer animation , and motion capture systems.

  3. Three-two pull down - Wikipedia

    en.wikipedia.org/wiki/Three-two_pull_down

    Film runs at a standard rate of 24 frames per second, whereas NTSC video has a signal frame rate of 29.97 frames per second. Every interlaced video frame has two fields for each frame. The three-two pull down is where the telecine adds a third video field (a half frame) to every second video frame, but the untrained eye cannot see the addition ...

  4. Group of pictures - Wikipedia

    en.wikipedia.org/wiki/Group_of_pictures

    The GOP is a collection of successive pictures within a coded video stream. Each coded video stream consists of successive GOPs, from which the visible frames are generated. Encountering a new GOP in a compressed video stream means that the decoder doesn't need any previous frames in order to decode the next ones, and allows fast seeking ...

  5. Video editing - Wikipedia

    en.wikipedia.org/wiki/Video_editing

    To showcase excellent video editing to the public, video editors must be reasonable and ensure they have a thorough understanding of film, television, and other sorts of videography. [1] Video editing structures and presents all video information, including films and television shows, video advertisements and video essays. Video editing has ...

  6. Uncompressed video - Wikipedia

    en.wikipedia.org/wiki/Uncompressed_video

    Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.

  7. Bit rate - Wikipedia

    en.wikipedia.org/wiki/Bit_rate

    The gross bit rate is related to the symbol rate or modulation rate, which is expressed in bauds or symbols per second. However, the gross bit rate and the baud value are equal only when there are only two levels per symbol, representing 0 and 1, meaning that each symbol of a data transmission system carries exactly one bit of data; for example ...

  8. Refresh rate - Wikipedia

    en.wikipedia.org/wiki/Refresh_rate

    The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image.

  9. Rate–distortion optimization - Wikipedia

    en.wikipedia.org/wiki/Rate–distortion_optimization

    Rate-distortion optimization (RDO) is a method of improving video quality in video compression. The name refers to the optimization of the amount of distortion (loss of video quality) against the amount of data required to encode the video, the rate. While it is primarily used by video encoders, rate-distortion optimization can be used to ...
