Viarte Conversion Notes

This page shows examples of high quality conversion and HDR/SDR noise reduction examples using our award-winning proprietary Viarte Technology. Examples were compressed using either HEVC or AVC/H.264. Simulated motion blur may be applied when converting from higher framerates to lower framerates. Accurate motion blur is essential and critical to reduce motion judder on playback and possibly achieve a film look. If you would like to see a particular video type conversion not shown below, please contact us for a private viewing. Before downloading and playing any clips, we recommend you read our smooth viewing guide page first.

Viarte Upresing & Down-Scaling Examples

• Sita Sings the Blues 1920x1080p_ntsc24 to 720x480p_ntsc24 scaling demo
• Sita Sings the Blues 1920x1080p_ntsc24 to 3840x2160p_ntsc24 scaling demo

Judder Reduction Examples

• crowd_run_1920x1080_50 to ntsc24p with added motion blur
• old_town_cross_1920x1080_50 to ntsc24p with added motion blur

Note: When adding simulated motion blur for FRC from 50p to 24p, some fine lines/details may appear less sharp than in the original 50p when viewed frame-by-frame. This same motion blurring would have occured on a real 24p camera.

Low Frame Rate Conversion Examples

Excerpts from Films: "How Sweet the Sound: The Blind Boys of Alabama",
"Cafe Glass" and "Finding The Gold Within"

Viarte frame rate conversion and digital remastering (deinterlacing, inverse telecine, noise reduction, up-scaling, aspect ratio conversion, etc) was used successfully for footage conversion of several feature length and short documentary films, including:

• "How Sweet the Sound -- The Blind Boys of Alabama" (16 minutes of the most challenging clips) by multiple-award winning director Leslie McCleave. The film was world premiered at the Nashville Film Festival on April 18 and 21, 2015. "The premiere went great!" said the director Leslie McCleave. Red carpet interviews can be found on the NaFF site here. To support this intimate film portraying one of the last great gospel quartets, please click here.
• "Cafe Glass" by director Wen Ren. The film was world premiered at the Tribeca Film Festival on April 16, 20, 22 and 25, 2015. "The screening went wonderfully! Full house all 4 screenings!" said Wen Ren.
• "Finding the Gold Within" by multiple-award winning, independent director/producer Karina Epperlein. The film was world premiered at the Mill Valley Film Festival on October 3 and 4, 2014.
