Specification
PixelMotion De-interlacing
PixelMoton 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.
Automatic Per-Pixel Video/Film detection & processing
Rather than making frame level decisions for video vs. film processing, typically causing severe artifacts to occur in sequences such as information tickers and video titles over film backgrounds, Teranex processing algorithms make pixel-level decisions, thus precisely processing film pixels as film and video pixels as video.
Multi-Direction Diagonal Filter (MDDF)
A true 10-bit diagonal interpolator that removes any “jaggies” and/or stair-stepping artifacts from de-interlaced video sources without blurring the image
Advanced Film mode detection
Detects and preserves the full resolution of film-based material with a wide variety of film cadences including:
- 24 fps Film - 3:2
- 25/30 fps film - 2:2
- DVCPro 24fps video - 2:3:3:2, 2:2:2:4
- Vari-speed broadcasts - 3:2:3:2:2, etc.
- Animation - 5:5, 6:4
- Anime - 8:7
Cadence Correction
Converts a broken 3:2 sequence (due to edits, etc) into a consistent 3:2 sequence. This aids in compression, making it easier for the compressor to detect the 3:2 sequence.
Scene Change Detection
Preserves clean cuts between scenes. Upon detecting a cut, the temporal aperture is reduced from 4-fields to 2-fields for the first frame in the new scene. This prevents uncorrelated data from being used in the interpolation process at scene boundaries.
Colorspace Conversion
Fully Automatic, but allows varying color primaries and luma equation for non-standard inputs and outputs.
Aspect Ratio Control
Allows selection from standard aspect ratios such as common top & bottom, common sides and anamorphic. Once selected, each aspect ratio offers adjustment for horizontal and vertical image size, position, pan & tilt, and trim.
Flexview
Flexview (available in 480i59.94 to 720p 59.94 & 1080i59.94 and 576i50 to 720p50 & 1080i50 up conversions) is a non-linear anamorphic aspect ratio designed for use when converting 4:3 material to 16:9 without the traditional distortion of a normal anamorphic stretch. Flexview leaves the center portion of the image untouched but provides increasing amounts of stretch towards the edges of the image, filling the 16:9 image without distorting the center action area.
Detail Enhancement
Extracts hidden detail buried in the image using this edge-sharpening filter based on a traditional film compositing technique called “Unsharp Masking.” Detail enhancement improves the image detail on a pixel-by-pixel basis, delivering upconverted SD that approaches HD quality.
Enhanced Conversion Decision List Processing
Easy to use controls capture all processing parameters based on timecode allowing the processing parameters to be fine tuned on a scene-by-scene basis. These parameters are then applied on a frame accurate basis to the source material.
Slow PAL Conversions
Using specially modified VTR’s in conjunction with Teranex’s Slow PAL conversion package, it is possible to achieve artifact-free standards conversion using 3:2 insertion and deletion as opposed to temporal interpolation.
Extensive Manual Overrides:
Although the automatic video/film detection logic is very accurate, in some instances post production houses prefer to have access to additional handles and thresholds to address very difficult content. A full set of manual controls is provided.
