Focus on Creativity

Get creative with a full range of remote post production activities and leave the playout logistics to us. Chroma+ allows you to connect through Streambox Cloud Services for real time collaboration in 4K HDR, UHD HDR, 2K HDR and HD HDR.




Support for 4K 4:4:4 HDR 12-bit means your remote collaborators / reviewers get to see your work the way you meant it to be seen.

Dolby Vision

Displays true-color, live video streams on professional grade monitors or TV’s with Dolby Vision support.

Best-in-Class Color

Our systems support all major color gamut standards, so you get to see Rec 709, for example, instead of a web browser / computer monitor (mis)interpretation.

Very Low Latency

Our ACT-L3 and ACT-L5 advanced codecs are highly efficient, which helps us achieve some of the lowest latencies in the industry.
