  • NEC tech detects illegal video uploads in seconds, MPAA swoons

    Surely by now you've come across something on YouTube that was flagged for copyright infringement, a process that's surely powered by massive teams of elves and other mystical creatures who watch each and every video uploaded to the site. NEC is looking to put them all out of work with a system that, with just 60 frames worth of video (about two seconds, typically) can identify copyrighted video with 96 percent accuracy and a false alarm rate of one in 200,000 -- even if it was copied from digital to analog or had captions added. This process is now part of the MPEG-7 Video signature tool, apparently the international standard, and works by creating signatures for copyrighted video that are just 76 bytes per frame. That's small enough for a desktop with a single core, 3GHz processor to churn through 1,000 hours of questionable video in one second, looking for matches all the while. Unless you freelance for the MPAA this isn't software you'll be running, but if you're a fan of the torrents there's a good chance that someone you know very indirectly will be.

    If you're like me, your professional or personal efforts toward video organization nirvana have been less than fruitful over the years. With video files spread across multiple formats and multiple storage locations, keeping everything readily available and tagged for reuse is a giant pain. On the consumer level I've tried iDive, iView Multimedia (now Microsoft Expression Media), even plain old iPhoto, and I'm checking out FootTrack; moving up the ladder, there are high-end choices like Cumulus/Mediadex and Final Cut Server. Finding that midrange, prosumer & network-enabled video cataloging tool, with options for MPEG-7 metadata, dynamic clip creation and embedded Spotlight comments in files -- well, I'm still looking, but Frameline 47's new version 3 seems to come pretty close to what I want. Frameline 47 is a $139 app that works both for an individual and as a networked tool, with Bonjour sharing and the ability to do the aforementioned Spotlight embeds, so your tags, comments and metadata travel with the files instead of with a master catalog; the full Workgroup edition is due at Macworld Expo, with additional capabilities for shared data. All your video files, on all your attached drives, in any QuickTime-readable format (plus WMV and more with Flip4Mac and Perian) can be scanned and thumbnailed into Frameline's search browser; once there, you can add annotations, identify clips for reuse, export your edited files, create webpage galleries, or pass along edit lists to Final Cut. There's a lot in Frameline to explore; probably more than I'll use for my personal projects, but if you have to wrangle a large collection of clips for your editorial work it's definitely worth a look. You can download a 14-day trial from Frameline's site... but we've got a special offer for TUAW readers courtesy of Frameline: 10 licenses to give away, free of charge. Read on for details on how to enter and win. P.S. Extra credit if you suss out why the app includes the number '47' in its name.
