In the United States and other countries where television uses the 59.94 Hz vertical scanning frequency, video is broadcast at 29.97 frame/s. For the film's motion to be accurately rendered on the video signal, a telecine must use a technique called the 2:3 pull down (or a variant called 3:2 pull down) to convert from 24 to 29.97 frame/s.
Apple Final Cut Express 4, Final Cut Pro 6.0.1, and iMovie '08-'09 (iMovie is bundled with all new Apple computers; Final Cut Express and Pro are sold separately) do not support editing of AVCHD clips directly. Imported AVCHD clips are automatically converted into the Apple Intermediate Codec format, which requires more hard disk space (40 GB ...
Variable frame rate (or VFR) is a term in video compression for a feature supported by some container formats which allows for the frame rate to change actively during video playback, or to drop the idea of frame rate completely and set an individual timecode for each frame. [1] [2] VFR is especially useful for creating videos of slideshow ...
Frame time is related to frame rate, but it measures the time between frames. A game could maintain an average of 60 frames per second but appear choppy because of a poor frame time. Game reviews sometimes average the worst 1% of frame rates, reported as the 99th percentile, to measure how choppy the game appears.
The advertised frame-rate of a specific display may refer to either the maximum number of content frames which may be displayed per second, or the number of times the display is refreshed in some way, irrespective of content. In the latter case, the actual presence or strength of any motion interpolation option may vary.
Adobe Premiere Pro is a timeline-based non-linear video editing software developed by Adobe Inc., distributed as part of the Adobe Creative Cloud suite. Primarily aimed at professional video editing, the program also provides an advanced set of tools for creating special effects and visual effects.
Thus the NTSC color subcarrier ended up as 3.579 54 MHz ( 315 / 88 MHz), the line scan frequency as 15. 734265 kHz ( 9 / 572 MHz) and the frame rate 29. 970029 Hz ( 30 / 1.001 Hz). [1] The altered frame rate meant that an hour of timecode at a nominal frame rate of 29.97 frame/s was longer than an hour of wall-clock time by ...
To convert a 24 frame/sec movie to 60 field/sec television, for example, alternate movie frames are shown 2 and 3 times, respectively. For 50 Hz systems such as PAL each frame is shown twice. Since 50 is not exactly 2×24, the movie will run 50/48 = 4% faster, and the audio pitch will be 4% higher, an effect known as PAL speed-up .
