imageConvert Product Family

• Unique de-interlacing and frame rate conversion techniques preserve full resolution of the input image
• Sophisticated film cadence detection modes find and fix broken 3:2 cadence for cleaner conversions
• Flexibility to provide the highest quality up, down, side, cross and standards conversions

The imageConvert application family provides a set of tools for converting from any DTV format to any other with uncompromising quality. imageConvert supports all standard and emerging video formats in a wide variety of line and frame rates. The programmable nature of the Video Computer platform enables Teranex to stay on the leading edge with new formats and processing algorithms for the most demanding content.

Teranex’s PixelMotion™ de-interlacing is often heralded as the finest de-interlacer available at any price. Since it is software based, it can handle the most demanding content. From broken 3:2 cadences to animation and vari-speed cadences to video titles on film backgrounds, PixelMotion preserves the full resolution of the input signal.

Optional temporal recursive noise reduction, in select up-conversions, removes random noise without softening the image and varies the processing aperture on a pixel-by-pixel basis to account for objects in motion.

imageConvert Features:

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.
