I've noticed that for some reason blend deinterlacing is still being used on all BBC Video footage (iPlayer, inline footage on News/Sports sites, etc). It looks naff, causes image doubling in areas of high movement and makes scrolling credits harder to read. (Also don't think it looks as good and halves the perceived framerate) As reference, the doubling is very noticeable on a recent episode of Hustle in the 'action areas': http://i46.tinypic.com/14jxctd.png (a deck of cards is being fountained upwards, falling down onto the camera - note the overlapping ghosts of the moving cards).
I first wondered if this was a limitation of how Flash renders interlaced-encoded video, but I happened to be watching a particular sporting event via an unofficial Justin.tv stream and the motion was fluid and crisp. From that I can only assume all BBC videos are encoded as progressive, and as such the Blend deinterlacing is burnt in, with the same going for Live streams... If the content is being deinterlaced from a broadcast source, why not use Bob or Weave? Blend just looks awful, motorsports/action looks dire and even regular stuff looks pants. So, in the absence of any known point of contact for the bods in charge of digitisation across the BBC's online platforms, can someone advise me as to whom I should be addressing my angry letters and suggestions for improvement? ;) - Sent via the backstage.bbc.co.uk discussion group.
