Before Cadence Detection
After Cadence Detection
Improper cadence detection can cause a loss of resolution,
resulting in moiré patterns. Advanced cadence detection
eliminates these annoying moiré artifacts.
Understanding the Teranex Processor
The Teranex Processor features patented processing technology for the highest quality conversion
between video standards, frame rates and resolutions. The incredible power of Teranex processing
includes: up conversion, down conversion, SD/HD cross conversion, SD/HD standards conversion,
cadence detection and removal, noise reduction, adjustable scaling, aspect ratio conversion including
Smart aspect, timecode conversion, 16 channel audio processing, and more.
Proprietary PixelMotion de-interlacing, 3:2 detection and detail enhancement, combined with a powerful
array processing module, provide the highest image quality up, down and cross conversions. The first step
in the conversion process is to identify whether the input material is video or film originated so as to apply
the appropriate filter to recover the full vertical resolution of the input material. The identification process
is fully automatic and selects either PixelMotion de-interlacing for video based material or 3:2 detection for
film based material.
PixelMotion De-interlacing
PixelMotion de-interlacing of video originated material produces perfect progressive frames in preparation
for further processing. The processing aperture is adjusted on a pixel-by-pixel basis, which preserves all
of the detail of the original interlaced image and eliminates jaggies in the output image, providing well-
defined edges on objects and producing the sharpest images possible.
3:2 Detection
3:2 cadence detection recognizes the redundant fields inserted during the conversion from 24 frames
per second to 30. This advanced 3:2 pull down filter avoids frame rate conversion artifacts and provides
the highest vertical resolution and motion quality.
Since the quality of the video de-interlacing is so high, there will be no difference visible in the vertical
resolution seen with film originated material and that of the de-interlaced video originated material.
Cadence Detection, Removal and Correction
Teranex is unique because it can automatically remove cadence (3:2 pulldown) from video when converting
to 24 fps, even when the footage has been previously edited and suffers from flash fields. That's perfect for
mastering clean online content! You can even take edited 3:2 sequences, remove the broken cadence and
re-insert clean cadence all in one pass.
