Aug 23 (Reuters) - A new digital theatre platform developed to keep audiences engaged during lockdown is being used by performers to take their shows to festivals far from home, and even to two events at once. Black Box Live, set up by Adelaide-based performer Joanne Hartstone and her partner, won accolades when it live-streamed shows around the world from the Adelaide Fringe earlier this year, which went ahead despite the pandemic, though with COVID measures in place. Now Hartstone is using the platform to take her show to not one, but two major fringe festivals abroad that this year are happening at the same time, without ever leaving Australia. The Edinburgh festival is held throughout August. After technical delays to adapt to pandemic times, the Hollywood Fringe, is taking place in the same month, from Aug. 12-29, rather than its usual time of June. Hartstone stars in "The Girl Who Jumped Off The Hollywood Sign," which live-streamed to Hollywood, from a performance at 1 p.m. (0330 GMT) Adelaide time and a separate show at 7.30 p.m. to the Edinburgh Fringe. Much as she misses the in-person appearances she made in Edinburgh and Hollywood in the past, Hartstone says streaming is becoming an art form in its own right that demands new skills.

I"m also having to make eye contact with the camera at a certain point." Edinburgh has chosen to mix live, live-streamed - meaning the audience watches as the performance is staged - and on-demand performances, which can be viewed at any time, although they are still based on a single-take recording of a show. Mindful of the huge Hollywood film industry, the Hollywood Fringe decided to include only live and live-streaming, despite the higher technical and cost barriers to live-streaming, especially for small theatre companies. "The live "anything can happen" aspect of theatre is how our community differentiates itself from the film industry," Lois Neville, operations director at Hollywood Fringe Festival, told Reuters. She said the festival planned to move back to June in future, but the extra time this year allowed "the pivot to hybrid". Now the infrastructure has been set up in venues and on the festival"s website, it is likely to stay. "We’ve seen the accessibility that livestream can provide to audiences that might not otherwise participate in fringe and will likely keep that element around for years to come," Neville said.
