The Coach House Studios has been sold to the live streaming and video production company Karma.

The deal was completed in May and sees the Twickenham Studios-based TV drama post-production and Digital Imaging Technician (DIT) firm re-named as Coach House Digital and its founder John Walbeoffe Snr step-down from day-to-day involvement.

All four full-time staff have been transferred with John Walbeoffe Jnr remaining as chief executive. Walbeoffe Snr will now work in a consultancy capacity. No financial details were revealed.

Karma chief executive Jon Gout said: “We’re excited to have Coach House in the Karma family. They align perfectly with our own digital strategy meaning OB, streaming, camera, production and post-production services are all under one roof.”

Karma, also based at Twickenham Studios, is on the BBC’s preferred supplier list for broadcast equipment wet hire.

Following the deal, Coach House Digital’s lab has been overhauled so that it can better handle LUT development, colour workflows, dailies and transcoding. A DIT diary service will be launched soon.

Walbeoffe Snr said: “The Coach House has always looked to take advantage of the best of technological and workflow advances for its clients. Karma has the same philosophy and, with their experience of working in different genres, the [two companies] will now have unequalled experience to offer novel and unique production solutions across a range of programming,”

Coach House Studios drama credits include Agatha Christie’s Poirot, Luther, The Thirteenth Tale, The Tunnel and Accused (pictured).
