StormHD has invested £300,000 in a facility-wide infrastructure upgrade.
The London post house has also expanded its facility with an additional 2,700 sq ft of space.
The extra space will house three additional offline suites, two online suites and an audio mixing studio with a large voiceover booth for animation and ADR recordings.
An additional 32TB Avid Unity ISIS system will also be installed at the Covent Garden site.
StormHD co-owner Tim Wheeler said: “As part of our infrastructure improvements we have also installed 1Gb fibre direct into our facility which will significantly improve our capacity to digitally deliver programmes.”
