1. A shooting format is a technical definition of a set of standard characteristics regarding image capture on photographic film, for either stills or filmmaking. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape.
2. The most common shooting format is 4-perf 35 mm. Feature films with aspect ratios of 1.85:1 and television programs may use this format. The cinematographer frames for the final aspect ratio, and that part of the image is used for electronic transfer to video or projection in theaters.
3. The 3-perf format was originally developed for television. Advancing the negative 3 perfs at time instead of 4 eliminated the extra space between frames. That extra space had been helpful in splicing 35 mm negatives together, but such splicing is seldom used in television production. It was once impractical for feature films but digital intermediates have made this a viable format for feature films.
4. This format is similar to 3-perf , but the camera pulls down 2 perfs instead of 3. 2-perf is used to create a 2.40:1 image with a minimum amount of film. Like Super 35, the image must be digitally or optically enlarged to a 4-perf animorphic intermediate/negative. This process was once called TECHNISCOPE.
5. 2K resolution is a generic term for display devices or content having horizontal resolution of approximately 2,000 pixels. Digital Cinema Initiatives(DCI) defines 2K resolution standard as 2048×1080.
6. 4K resolution, also called 4K, refers to a horizontal screen display resolution in the order of 4,000 pixels.] There are several different 4K resolutions in the fields of digital television and digital cinematography. In television and consumer media, 3840 × 2160 (4K UHD) is the dominant 4K standard. In the movie projection industry, 4096 × 2160 (DCI 4K) is the dominant 4K standard.
7. High-definition video is video of higher resolution and quality than standard-definition. While there is no standardized meaning for high-definition, generally any video image with considerably more than 480 vertical lines (North America) or 576 vertical lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts.
8.The number of lines in the vertical display resolution. High-definition television (HDTV) resolution is 1,080 or 720 lines. In contrast, regular digital television (DTV) is 480 lines (upon which NTSC is based, 480 visible scanlines out of 525) or 576 lines (upon which PAL/SECAM are based, 576 visible scanlines out of 625).
9. A frame or field rate can also be specified without a resolution. For example, 24p means 24 progressive scan frames per second and 50i means 25 progressive frames per second, consisting of 50 interlaced fields per second. Most HDTV systems support some standard resolutions and frame or field rates.
10. Most computers are capable of HD or higher resolutions over VGA, DVI, HDMI and/or DisplayPort.The optical disc standard Blu-ray Disc can provide enough digital storage to store hours of HD video content. Digital Versatile Discs or DVDs (that hold 4.7 GB for a Single layer or 8.5 GB for a Double layer), are not always up to the challenge of today's high-definition (HD) sets.
