Why Alchemist?

 

World’s best format and frame rate converter using Grass Valley’s 25 years of image processing expertise 

Optimized to offer the very best picture quality however complex the source file – even for the challenging low frame rate inputs

Guarantees consistent quality with no user intervention – optimal results first time, every time

Now with Adaptive Cadence Technology and off-speeding with audio pitch correction

 

Typical applications

 

Post production house converting premium content to for digital cinema distribution, for example 4K 25p to 4K 24p

Global broadcaster converting UK drama for US distribution, for example 1080 25p to 1080 29p

International broadcaster converting content for their On Demand TV service, for example 525 59i to 720 59p

 

What's new in GV File V3.0?

 

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.

Processing times have been reduced by up to 40%; the exact performance improvement will be system and conversion specific (positive improvements have been measured in most cases).

Added Timecode overlay
