Bright Technologies Inc., a producer of technology for shared media, launched a “standalone” version of BrightClip, which seeks to eliminate fragmented, randomized and interlaced file layout that is caused by large video files being squeezed into file system “holes.”
On April 17, 2012, “BrightClip SA” was unveiled at the National Association of Broadcasters Show in Las Vegas. BrightClip SA searches a file system for a single chunk of continuous free space that will hold a large file containing megabites of data.
A major problem for the broadcast industry is that performance is lost from their SAN systems, said Catrin Beck, Bright Technologies’ marketing director. “Every SAN system is subject to degradation over time, and the major issues are basically a lack of intelligence of the file system and the physical limitations of IT hardware.”
BrightClip eliminates the most disruptive and productivity-damaging factors for a studio workflow process, including high latencies, dropped frames and stuttering video, according to Bright Technologies. The BrightClip technology maximizes data storage performance and reliability, stability and predictability in every SAN environment allowing the facility to focus on their creative processes, reducing downtime and maintenance and increasing profitability, the company says.
BrightClip also handles large streaming file formats and file-based clip sequences—without fragmentation, sequence randomization or interleaving by eliminating all root causes, the company says. It proactively creates and maintains optimal file layout on the storage at all times, and in real-time.
Standard file systems are space optimized versus performance optimized, meaning the file systems try to use the existing storage space in the best possible manner by breaking up files—even if they are large files containing hundreds of megabites—into thousands of little bits and pieces of information, according to Beck.
In an effort to use the system space in the best possible manner the file systems squeeze that information into the empty spaces, or holes, she said. At first it sounds pretty smart, but for workflows with large files, such as in video post production, the file system breaks it up into little chunks, and the disc ends up with a fragmented, randomized and interlaced file layout. “That means the disc head has to jump back and forth like crazy to gather up the data, and that is why performance is lost,” Beck said.
“BrightClip adjusts allocation sizes intelligently and dynamically, and it does that on the fly while adjusting the allocation sessions in real time,” she said.
