HDR/SDR Noise Reduction Applications and Key Benefits

isovideo Viarte conversion services offer a suite of the best quality content transformation and HEVC encoding services, described in the sections below. We are passionate about technology and films. We strive to make ALL content look its very best. As we have developed all of our processing technology in-house, you can be rest assured that your content is at the best hands, and we can deal effectively with any unforeseen corner cases, should they arise.

SD Interlaced to HD Interlaced/Progressive
HD Interlaced to HD Interlaced & HD/UHD/4K Progressive Conversion
  • Second-to-none interlaced to interlaced/progressive conversion quality, with options to up-scale/down-scale. High quality SD material can be viewed at 2.5x the display picture height when converted to HD or UHD TV. Similarly, UHD/4K from 1080i60 can be viewed at 1.2x picture heights. A high quality viewing experience can be achieved on larger HD/UHD TV displays for typical viewing distances in most households for all Viarte converted contents.

Precise Temporal Conversion

Superior temporal conversion by up to +/-10% allows material to fit a time slot, and without introducing visible artifacts or judder due to frame dropping/duplication. The audio tempo is correspondingly changed with the video. The input sources can be any of progressive, interlaced, 32-pulldown, or mixed.

In addition, multiple tempo change adjustment values can be defined and localized by time and duration, allowing some regions to be preserved, and others squashed or extended.

Robust and Sophisticated Inverse Telecine &
Mixed Mode Handling of Interlace | Inverse-Telecine | PSF
  • Best quality available 2:3 and 2:3:3:2 pulldown removal (inverse telecine) with mixed/broken/random cadence handling in noisy conditions. (See our Youtube remastered classic movies here).
  • Progressive segmented frame (PSF) detection and handling for progressive inputs marked as 59.94i or 50i. PSF is reliably detected and handled amongst telecine or interlaced content. (See our success story "Metallica: "Some Kind of Monster" here).
Breakthrough Quality HDR/SDR Noise Reduction and
Highest Quality HEVC Encoding
  • Breakthrough HDR/SDR GPU MC noise-reduction technology achieves up to 10db noise reduction, while reducing flicker and preserving details and edges. When combined with scaling, viewers can enjoy a near immersive viewing experience not normally achieved with SD sources.
  • Significant HEVC/H.264 bandwidth savings. For noisy sources, results show up to a 80% file size reduction.
  • Viarte noise reduction provides a better foundation for any SDR to HDR up-conversion (offered by other companies).
  • With denoise, we are also providing the highest quality HEVC encoding at any given bitrate, for mobile, premiere OTT, ATSC 3.0 broadcast and Blu-ray applications. Stay tuned for further announcements on Viarte cloud fast HEVC encoding.
Encoding, Color Conversion, and Other Benefits
  • Multiple encoding formats are provided, such as MPEG-2, IMX, HEVC, H.264, Prores, XAVC(decoding), AVC-Intra, DNxHD, XDCAM-HD, DVCPRO-HD, DPX and JPEG 2000, etc. with target bit-rate and profile control.
  • Color space conversion between rec.601, rec.709, DCI-P3, BT2020 and ITU.
  • Accurate and flexible output timecode control
    • including SMPTE-drop-frame count, or exact frame count,
    • output timecode can be adjusted according to configuration, or can pass through from the input.
  • Logo insertion and a proprietary water-marking process are supported to protect your content.
  • Secure content handling - including during file transfers and on our premises. Your content is always stored on encrypted filesystems, which drastically reduces the risk of content loss.
  • DPP AS-11 compliant.

Viarte Digital Remastering Services Introduction

Digital remastering is a super-set of standards conversion, mainly because frame-by-frame inspection is often required, and the source material may have condition problems. These problems include combinations of SD, film, HD with different frame rates, scan types, varied noise types and noise levels, and inaccurate or misleading metadata.

Material is sometimes further subjected to an add-hoc editing process that results in damaged video, such as mixed/random cadences, add-hoc crossfades, dropped/duplicated frames, etc.

It is a technical challenge to bring all this content into the best shape so it can provide a near-immersive viewing experience when presented online or on Blu-ray, and especially for larger displays.

Viarte digital remastering service seamlessly ties and engages all of our breakthrough video processing technologies. It could make your valuable SD and HD content look better than ever before when displayed on UHD/HD and for Blu-ray production, while benefiting from substantial H.264/HEVC compressed bandwidth savings for online distribution, a true win-win combination.
