Interlacing and Deinterlacing Background
More than 60% of existing video is interlaced and it is still prevalent in many studio and distribution systems.
Interlacing is easy to do at the source, but unfortunately it is
very difficult to undo (deinterlace) to produce high quality progressive results, and it requires a
lot of processing to get reasonable quality. Furthermore it is
mathematically proven that perfect deinterlacing is impossible to achieve.
An inferior generic deinterlacer typically results in
Importance of Deinterlacing Quality
Poor image quality: trade off vertical resolution for lower flicker.
This results in considerably fewer effective lines of resolution than the 1080i HD format would indicate.
Poor x264/HEVC compressibility: it inevitably causes more errors (more flickering),
resulting in significantly larger compressed files.
Poor standards conversion quality:
error in deinterlacing are further magnified in subsequent processing such as motion-compensated frame-rate conversion. The motion estimation algorithms make more mistakes, generating more visible artifacts, thus also leads to poorer image quality.
The fundamental prerequisite for efficient and effective monetization of existing interlaced material via the web, or mobile devices.
A key factor to achieving additional significant x264/HEVC compressed bit-rate reductions on network bandwidth.
A key to high quality standards conversion.
State-of-the-Art Viarte Deinterlacing
Superior Deinterlacing Quality: Viarte's deinterlacer can pass through the original fields to the output frames completely unchanged, without output filtering, while producing very little flicker. It is the only standards converter available that produces clean and sharp video, while saving an additional 17% x264/HEVC compressed bitrate reduction on average.
Deinterlacing, Archiving and Monetization Efficiency:
Content owners can now completely replace their original interlaced video archive with Viarte's deinterlaced version, allowing:
Viarte is win-win enabling technology due to its unique combination of quality and compressed x264/HEVC bit-rate reduction, breathing new life into a wealth of interlaced archives.
lossless or near lossless recovery of the original material should the need arise, and
significantly improve in their media workflow efficiency by pre-deinterlacing all interlaced media files, making them web-repurposing/delivery ready.
