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. Variable frame rate - Wikipedia

   Variable frame rate (or VFR) is a term in video ... or if the video contains a combination of 24/25/30/50/60 FPS footages and the creator or editor of the video ...

5. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   CBR is commonly used for videoconferences, satellite and cable broadcasting. VBR is commonly used for video CD/DVD creation and video in programs. Bit rate control is suited to video streaming. For offline storage and viewing, it is typically preferable to encode at constant quality (usually defined by quantization) rather than using bit rate ...

6. Film frame - Wikipedia

   en.wikipedia.org/wiki/Film_frame

   In moving picture (TV) the number of frames scanned per second is known as the frame rate. The higher the frame rate, the better the sense of motion. But again, increasing the frame rate introduces technical difficulties. So the frame rate is fixed at 25 or 29.97 . To increase the sense of motion it is customary to scan the very same frame in ...

7. Interlaced video - Wikipedia

   en.wikipedia.org/wiki/Interlaced_video

   For a fixed bandwidth, interlace provides a video signal with twice the display refresh rate for a given line count (versus progressive scan video at a similar frame rate—for instance 1080i at 60 half-frames per second, vs. 1080p at 30 full frames per second). The higher refresh rate improves the appearance of an object in motion, because it ...
