For viewing native PAL or SECAM material (such as European television series and some European movies) on NTSC equipment, a standards conversion has to take place. There are basically two ways to accomplish this: The framerate can be slowed from 25 to 23.976 frames per second (a slowdown of about 4%) to subsequently apply 3:2 pulldown .
When operating in this mode most of them do not output a true (625/50) PAL signal, but rather a hybrid consisting of the original NTSC line standard (525/60), with colour converted to PAL 4.43 MHz (instead of 3.58 as with NTSC and South American PAL variants and with the PAL-specific phase alternation of colour difference signal between the ...
When transferred to NTSC television, the rate is effectively slowed to 23.976 FPS (24×1000÷1001 to be exact), and when transferred to PAL or SECAM it is sped up to 25 FPS. 35 mm movie cameras use a standard exposure rate of 24 FPS, though many cameras offer rates of 23.976 FPS for NTSC television and 25 FPS for PAL/SECAM.
Consequently, it has become popular with low-budget film/video makers. It is the successor to the HV10, which was Canon's first consumer HDV camcorder. The NTSC-region camera shoots at 24p which gives a film-like look in PF24 mode, using 2:3 pulldown in a 60i stream. In PAL regions, it can record in native 25p mode and as such does not require ...
To store the digitally encoded audio/video on a standard NTSC Video8 cassette, the tape must be run at double the Hi8 speed. Thus, a 120-minute NTSC Hi8 tape yields 60 minutes of Digital8 video. Most Digital8 units offer an LP mode, which increases the recording time on an NTSC P6-120 tape to 90 minutes.
That is a special professional video camera that used a video camera tube would be pointed at a cathode ray tube video monitor. Both the Camera and the monitor could be switched to either NTSC or PAL, to convert both ways. Robert Bosch GmbH's Fernseh Division made a large three rack analog video standards converter, Model NC 56 P 40. These were ...
This is achieved using complicated circuitry involving a digital frame store, the same method used for converting between NTSC and the 625/25 standards. The fact that the colour encoding of PAL-M and PAL/625/25 is the same does not help, as the entire signal goes through an A/D-D/A conversion process anyway.
NTSC and PAL image sizes are smallest, with a width of 720 (or 704) and a height of 480 or 576 lines. The third size is HDTV images that have 720 scan lines in height and are 1280 pixels wide. The largest size has 1080 lines high and 1920 pixels wide. 1080-line video is actually encoded with 1920×1088 pixel frames, but the last eight lines are ...
