Why Quasar File? / Features

  • World’s best intelligent adaptive de-interlacing technology delivering maximized vertical resolution for all types of content
  • Optimized to deliver consistent quality for all interlaced and progressive content

Typical applications:

  • International broadcaster converting SD and HD interlaced files for progressive transmission
  • Playout service provider down converting HD assets to SD assets for global transmission
  • Post production house up converting HD material to 4K for cinema screening

Trial software can be run on a single AMD R9 270 GPU and will typically offer a 1080i > 720p conversion duration of two times program length for under $200.

GV File V3.0 - What's new?

  • HDR to HDR processing to and from PQ / S-Log3 / HLG 
  • HDR (PQ / S-Log3 / HLG) down conversion to SDR (BT709 / REC601) using Grass Valley's Advanced Tone Mapping
  • SDR (BT709 / REC601) up conversion to HDR (PQ / S-Log3 / HLG)
  • Decoding of AAC audio is now supported for all relevant source file types.
