Cameras film at many frame rates, so when programs are distributed around the world, a frame-rate conversion, or standard conversion must be performed.
The fastest way to do this is using hardware devices, which are truly real-time. We have three Standards converters here, with advanced image processing, noise reduction, timecode regeneration etc.
We monitor the conversion in realtime on a pair of identical side-by-side monitors, to ensure the quality is excellent.
We can also perform the more difficult 24fps <-> 25fps conversion.
