Video Conversion - Video Tape Conversion
NTSC PAL SECAM
Most countries around the world use Broadcast Standards that are incompatible
with other countries. For example, a video recording made in the UK could not be played on US standard VCR's or
shown on the TV.
Effectively, there are three main world standards. These are NTSC PAL SECAM. Within each of these three
standards, there are a number of variations. For a breakdown of the technical aspects of each standard, take a look
at the Video Formats page.
To find out which standard each country supports, take a look at our Worldwide Video
Tape recording and playback times also vary dependant on the standard used by the video recorder and also the
tape used. Take a look at our Video Tape Comparison Charts to find out how long a
particular tape will last across different standards.
The process of Video Conversion takes the video signal which has been recorded or broadcast in one standard and
converts it to the new video format. This is achieved by using a Broadcast Quality Digital Video Standards
Converter connected between the original video source and the new output source.
The video converter will normally include integral Time Base Correction to aid in stabilizing video tape
sources. High performance is achieved by using Digital Conversion and Digital Comb Filtering in the decoding
Video Tape Conversion
In the case of video tape conversion, a minimum of two video machines are required. The 'Playback' machine must
be capable of playing back the format of the tape being converted. If the tape is in SECAM format, then the machine
must be able to play SECAM tapes.
The 'Record' machine must also be capable of recording in the format that the converter outputs. If the
conversion is to NTSC, then the machine must have NTSC record facility.
We use multi-standard video machines that are capable of NTSC 3.58, NTSC 4.43, PAL, SECAM and MESECAM both
record and playback.
