\"ZombieIn my recent comparison of inexpensive Blu-ray players for Sound and Image<\/em> magazine<\/a>, I introduced a new picture quality test. Here’s how I explained it:<\/p>\n

In assessing picture quality, I made resort to a test that shall henceforth be known as ‘Zombie Strippers’. The name is simply too delicious to resist.I base the test on playing back a movie trailer on the recently released Sony Pictures Entertainment Blu-ray of Felon<\/a><\/em>. That is a fine and serious movie, well worth viewing, so forgive it for also carrying a trailer for a dreadfully bad movie called Zombie Strippers<\/a><\/em>. This, apparently, is going to be released on Blu-ray. The trailer itself is in 480i format.<\/p>\n

I’ve noticed an odd thing about Blu-ray. NTSC DVDs generally carry their movies in 24 frames per second format (although the frames are divided into interlaced fields). The DVD player performs the 3:2 pulldown required to convert this to 60 frames per second. But on Blu-ray, Special Features presented in 480i format tend to have already had the 3:2 pulldown performed upon them. This uses more space, but Blu-ray has space to burn. So about two fifths of the frames are heavily interlaced, presenting a deinterlacing challenge for some Blu-ray players. It was on this trailer that I first noticed this behaviour. So ‘Zombie Strippers’ will be the test.<\/p>\n

That stuff about how the 480i video can be presented in different ways is covered in somewhat more detail here<\/a> (see the section ‘NTSC — where interlacing goes wrong’).<\/p>\n

Incidentally, the pack shot I’ve shown for this movie I grabbed from the persistent storage USB memory stick I used in a Blu-ray player. It had been downloaded from the Internet by the BD-Live facility on one of the Sony BD-Live discs I’d been checking out.<\/p>\n","protected":false},"excerpt":{"rendered":"
