We can convert your NTSC video to the South African PAL format and provide them for you on the format you need.

The video standard in the United States have been set by the National Television Standards Committee, which is called NTSC in short. This standard has been adopted in other countries as well, such as, Japan. NTSC standard has 29.97 interlaced frames of video a second, often specified as 30 frames per second, with 525 lines per frame. Out of these 525 lines, 480 lines are used for vertical resolution and the rest are used for synchronisation, vertical retrace, and other data such as captioning.More about the NTSC format

The scan lines in NTSC are interlaced, with two fields containing the odd scanned lines and the even ones respectively. This provides a near flicker free image utilising 59.94Hz refresh rate, which comes to 60 cycles at 1.001 seconds. This is close to 60Hz alternating current power used in the United States.

In trying to convert NTSC to PAL, the most difficult part is the mismatch of the frame rate between the three. In the process of this conversion, the equipment used is made to guess the contents of the intermediate frames which introduce artifacts. This is quite detectable by trained eyes. A frame consists of a packet of composite image information and the 525 lines per frame in the NTSC standard may contain up to 16 million colours. A composite signal would mean a video signal which contains all the colours, such as, red, blue, and green signals and may also consist of audio signals.

Radio interferences is known to disturb NTSC transmission, therefore by the time the picture gets transmitted on to your TV screen, the picture often loses its colour balance. This necessitates the inclusion of a “tone” or “hue” control on NTSC sets, which is not necessary in PAL TV sets. Further more, some observers find that with NTSC, the 525 line resolution of NTSC results in a lower quality image than the hardware is capable of.
