Viarte HDR-to-SDR Tone Mapping | SDR-to-HDR Up-Conversion |
Digital Remastering | Standards Conversion Server
Viarte embodies several key breakthroughs in stream/file-based SDR-to-HDR Up-Conversion,
HDR-to-SDR tone mapping, 4K/UHD/HD/SD digital remastering, MC standards conversion/transcoding technologies,
offering significant advances in conversion quality,
HDR/SDR MC noise reduction, HEVC/AVC compression efficiency, throughput, latency and server architecture.
1) 100% original field pass-through (no output filtering) for full vertical resolution, yet with very little visible flicker.
2) on average 21% H.264/HEVC compressed bit-rate reduction, when compared with
compressing interlaced directly. Together these two attributes provide an objective
measure of deinterlacing quality. Our deinterlacing has enabled filmmakers to
shoot in ntsc60i and show their film on the big screen, and also on Blu-ray.
100% recoverable progressive archives, completely eliminating the need for interlaced archives.
This improves workflow efficiency by avoiding repeated deinterlacing.
Sophisticated inverse telecine technology hardened and used in over 40 episodes of a TV sitcom.
It achieves over 99.9% automation and handles extreme noise variation, random-cadences,
mixed and broken-cadences, cross-fades, etc. It does not add unnecessary duplicated frames.
It uses true motion calculations (not motion adaptive) for extremely reliable scene-change detection,
achieving as near perfect results as possible.
Mixed interlace/pulldown/progressive (PSF) handling.
Highest-quality video scaler and rotator available,
with natural-looking edge enhancement and absolutely no ringing: enables superior upresing from SD to HD or HD to UHD/8K, or scaling down to mobile.
Independently scales in the vertical and horizontal directions, allowing Pixel Aspect Ratio conversion,
while simultaneously performing image rotation to correct for tilted source images.

Viarte Uses the Highest Precision Computation Pipeline
32-bit internal component calculations and 16 bits I/O for all Y,Cb,Cr components,
maintaining highest system precision throughout.
EXR to EXR floating-point file format processing, ensuring the highest computational precision throughout the Viarte pipeline;
Efficient On-the-fly Viarte Splitting Technology
Built on our Super-Fast Lossless Video Compressor/Decompressor
Allows low-latency (typically between 10 to 60s), on-the-fly stream-based processing
from ingest to the first output frame. Latency varies with workload for a given resource, but it is not file-size dependent.
Enables highly efficient scalability, and offers high throughput.
Viarte cluster throughput increases nearly linearly with the number of servers in a cluster.
High throughput when combined with GPU acceleration.
Efficient Viarte Architecture Features (Including Color Conversion)
Highly efficient concurrent multi-transformations via streamlined pipelining and optimized execution.
Up to 2000 input files can be queued in a single command, either via multi-file copying or drag-and-drop.
Highly robust operation, it can handle as many jobs as you throw at it 24/7, while optimizing its throughput to its resources.
Extremely flexible configuration and control, supporting:
Flexible output control:
Concurrent up/down/cross conversions between any interlaced or progressive
video/film with any combinations of frame-rates (24/1.001, to 120f/s, etc) and resolutions (mobile to 4k, 8k, etc).
Multiple codecs, such as HEVC, H.264, Prores, AVC-Intra, DNxHD, XDCAM-HD, and DVCPRO-HD, etc.
with target bit-rate or quality tuning, when available.
DPP AS-11 compliant.
Multiple container formats - such as mov, mxf, mp4, mkv, ts/mts/m2ts/ps, etc.
Flexible advanced control capabilities:
Configurable, accurate simulated motion-blur capability to achieve that beautiful film look.
This is especially important when down converting from high frame rate material (such as 60p, 60i, or 50p, 50i) to
lower frame rate targets (such as 24p, 25p, 30p).
Best available proprietary dot-crawl removal processing.
Audio-video delay adjustment to compensate for incorrect metadata.
Conversion start time and duration adjustment.
Automatic and/or manual input cropping.
Automatic handling of mixed and broken cadences, such as transitions between 2:3 pulldown, advanced pulldown (2:3:3:2) and interlaced, etc.
Safe handling of PsF material, with various modes to handle misleading input metadata.
Accurate and flexible output timecode support includes SMPTE-drop-frame count, or exact frame count, as well as output offset adjustment and timecode-burn-in.
Configurable output file transfer that automatically executes data copy commands such as FTP/scp/mv, etc upon job completion.
Color space conversion between rec.601, rec.709, DCI-P3, BT2020 and ITU.
Logo image insertion.
Timed/positioned text burn-in.
Proprietary water marking technology.
Supports integration of third-part command-line tools to augment/expand Viarte features
through automatic pipeline execution, such as very fast file transfer, new codecs, new formats, etc.)
Easy mountable integration with any existing IP-based, stream-based or
file-based workflow systems (through configurable NFS/SMB protocols)
such as acquisition, post production, archive/storage systems, and delivery/streaming servers, etc.
Highly efficient scalability and network utilization.
With 10Gb LAN, Viarte can effectively scale to a large server farm (to the limits of a class-C network).
Viarte's scalability supports expansion to easily accommodate 4K/8K and high frame rates material,
with automatic and redundant server discovery, and synchronous individual server maintenance shut-down.
Built from the ground-up with all of the above-mentioned breakthrough technologies,
Viarte is a powerful on-the-fly content transformation and HEVC/AVC encoding engine with unparalleled capacity to
achieve low-delay, high-throughput, highest quality 4k/UHD/HD/SD conversion
and encoding at any bitrate
on both IP streams or files.
Using a Viarte cluster, OTT providers, content owners, broadcasters, sport networks and post-facilities
can provide sharper, smoother, cleaner and smaller-footprint Video while significantly improve their
IP-studio workflow efficiency and automation, without limiting future expandability.
