Baraka is a 1992 non-narrative documentary film directed by Ron Fricke. The film is often compared to Koyaanisqatsi, the first of the Qatsi films by Godfrey Reggio for which Fricke was cinematographer. Baraka was the first film in over twenty years to be photographed in the 70mm Todd-AO format, and the first film ever to be restored and scanned at 8K resolution.
Following previous DVD releases, in 2007 the original 65 mm negative was re-scanned at 8K resolution with equipment designed specifically for Baraka at FotoKem Laboratories. The automated 8K film scanner, operating continuously, took more than three weeks to finish scanning more than 150,000 frames (taking approximately 12–13 seconds to scan each frame), producing over 30 terabytes of image data in total. After a 16-month digital intermediate process, including a 96 kHz/24 bit audio remaster by Stearns for the DTS-HD Master Audio soundtrack of the film, the result was re-released on DVD and Blu-ray Disc in October 2008. At the time, project supervisor Andrew Oran described this remastered Baraka as “arguably the highest quality DVD that’s ever been made”. Chicago Sun-Times critic Roger Ebert described the Blu-ray release as “the finest video disc I have ever viewed or ever imagined.” (Wikipedia)
26,3 GB Blu-ray untouched file of course is the source of this 25 years anniversary upload. Of course YouTube needs to compress it a lot to be streamable. So this is just a preview and of course you need to buy the historic disc to enjoy that deep unprecedented quality.
