Viarte Conversion Technology Overview -
What is so Unique about It?
Superlative image processing quality for digital remastering and standards conversion, which includes:
Pixel-accurate, GPU accelerated any-to-any Motion-Compensated (MC) frame-rate conversion technology
Duplicated frames can be automatically removed prior to frame rate conversion for smoother motion results.
The tempo can be adjusted by up to +/- 10% to fit material into a specified time slot.
The best GPU MC deinterlacing and inverse telecine technology
including automated handling of mixed cadences, PSF, etc.
Viarte inverse-telecine automatically detects and corrects broken cadences.
It uses true motion calculations for reliable scene-change detection,
achieving as near perfect results as possible.
Superbly sharp GPU video scaler/rotator
from mobile to 4K/8K,
with natural-looking edge enhancement, and absolutely no ringing, enabling highest-quality SD to HD or HD to UHD/4K/8K upres
(see this crowd_run
demo showing continuous scaling/rotation).
The best available proprietary dot-crawl removal processing.
Breakthrough quality, GPU accelerated detail/edge-preserving HDR/SDR MC noise reduction.
Viarte noise reduction prior to HEVC/AVC encoding achieves up to an 80% further reduction in output file size or bitrate, depending on noise levels.
The highest quality HEVC encoding at any given bitrate, from mobile, premiere OTT, Blu-ray,
to potential medical applications, etc; and the lowest bitrates for a given PSNR, while preserving sharpness & subtle detail.
32-bit internal component calculations and 16 bits I/O for all Y,Cb,Cr components.
EXR floating-point input file format processing ensures the highest computational precision and dynamic range into the Viarte pipeline;
Very fast conversion service due to Viarte's low-latency, high-throughput, near-linear scalability, and GPU acceleration.
Extremely flexible configuration to support all your format needs.
Viarte's proprietary state-of-the-art motion processing quality is the best available.
It is unique in that it is not perturbed by
fast luminance variations, and has almost no occlusion artifacts for clean sources.
Viarte Advanced HDR to SDR Tone Mapping Technology Overview
The new GPU accelerated proprietary advanced HDR to SDR tone mapping
works for all open standard HDR sources. In particular, it complements our advanced SDR to HDR,
It allows conversion to be used in a single stream, backwards-compatible SDR distribution.
for a genuinely improved vivid SDR+ viewing experience on any existing SDR display device,
from TVs to cell phone, including current Cinema projection systems.
Sharpness and local contrast is maintained as much as possible at all light levels,
with minimal saturation in bright areas, and therefore minimal loss of HDR detail.
Creative intent is optimally preserved by keeping maximum possible detail,
accurate color balance, the overall brightness impression, and highlights, while complying with rec709.
Viarte tone mapped results are more vivid than other backward-compatible SDR, which uses simple tone-mapping curves
that reduce local contrast, and appear dull by comparison.
Fast CUDA implementation of tone mapping from ST2084 (PQ at up to 10000 nits) down to, for example,
PQ at 1000 nits, HLG (ARIB STD-B67), or rec709. Other transfer function supported include Sony S-log2 and S-log3.
Color conversion (between ACES, BT2020, DCI-P3-D65, rec601, rec709, S-gamut3, etc.) is performed as necessary, and
constant and non-constant luminance color matrixing is also supported.
On-the-fly automatic HDR to SDR tone mapping allows HDR live event broadcast and OTT streaming applications.
New HDR productions can immediately reach widespread SDR audiences for an SDR+ viewing experience, and with minimal additional capital
expenditure for distribution, while content is future-proof and ready for the newer generations of HDR display technology.
Awards and Viarte Conversion in Cinema & Blu-Ray Applications
Viarte was one of five (of 1500 exhibitors) winners of the prestigious Game-Changer Awards
by the IABM and the NAB in 2013.
Viarte was recognized as having the greatest potential to revolutionize the industry by a panel of impartial experts.
All Viarte's processing technologies have been used in either film and/or Blu-Ray production applications. For example,
Viarte server was used for
in two-time Academy-Award winning director
Ron Howard's "Made in America". Their editors compared our results with several
well-known existing solutions. Our technology “clearly bested” all major competitors,
including all other leading solutions (software or hardware).
The film work involved 59.94i deinterlacing and frame-rate conversion/blurring to 24p.
Viarte frame rate conversion technology was also successfully applied to convert the feature-length documentary
"Finding the Gold Within",
by independent director/producer Karina Epperlein (from 1080p29.97 to 1080p23.976) (see the
The converted film was world premiered at the Mill Valley Film Festival on October 3, 4 and 12th, 2014.
isovideo Viarte digital remastering services have also been successfully applied to the
Metallica: "Some Kind of Monster"
feature documentary Blu-ray release.
The Blu-ray was released on November 24, 2014.
More information can be found in the press release.
The new trailer of the film can be seen here.
isovideo LLC was credited for footage conversion in American biographical film "Love & Mercy" directed by Bill Pohlad.
The film is about musician and songwriter Brian Wilson of the Beach Boys. The trailer of the film can be seen
Viarte services have been used for several digital remasterings, including the award winning "Take Every Wave: The Life of Laird Hamilton"
by Rory Kennedy, which premiered at Sundance Film Festival and also screened at the 2017 Sarasota Film Festival.
Nearly 70% of existing video is interlaced - it is still prevalent in many studio and distribution systems.
Interlacing is easy to achieve, but deinterlacing to high quality progressive is very challenging.
Furthermore it can be shown mathematically that perfect deinterlacing is impossible to achieve.
Deinterlacing is key to high quality remastering and standards conversion.
Viarte achieves the best quality deinterlacing results available today. It is the only technology offering 100%
vertical resolution with very little or no visible flicker. Furthermore, at that resolution, it achieves a
substantial 21% average bit-rate reduction in HEVC/H.264 versus compressed interlaced - a truly objective measure
of deinterlacer quality.
