Basically, your computer monitor shows an entire frame of video at once. So 30 full frames are displayed by your monitor every second. This is called progressive scan. Pretty simple, right? TVs display a bit differently. Each frame is broken into two subframes, or fields, that are 1/2 the resolution of a frame. A TV screen first draws the even field (all the even scanlines on the TV) and then the odd field. So it shows video at 30 frames per second = 60 fields per second. This method of display is called interlacing. If an object is moving rapidly across the screen, it won't be at the same position in an even field as it was in the odd field. This creates problems when you try to watch video originally for television on a computer. The computer tries to show both fields at once, which looks fucked up because you're looking at an object that's in two places at one time. So a de-interlacer's entire job is to somehow blend the two fields so that they look like one nice frame when viewed in progressive scan. There are various methods for doing this, and hopefully whatever you're editing on has got a good deinterlacer. Two good explanations of this can be found below: http://neuron2.net/LVG/interlacing.html http://www.animemusicvideos.org/guides/avtech/ (and more specifically, http://www.animemusicvideos.org/guid...ech/video2.htm ). I'm sure that Matt of NYU fame knows more than me, but that's a good place to start! Last edited by themire; 01-23-2010 at 12:09 PM. |

On that note, the iPod compatability setting I'm now using is an automated process built into Quicktime Pro, and doing some research I believe it de-interlaces as part of the process. But if it doesn't, I don't wanna fuck with it right away. Any little tiny thing I've changed fucks things up for one kind of iPod or another, so I'll go for stability over lack of scanlines any day. It's kinda strange that all video encoding doesn't de-interlace as a matter of course, since it sounds like it's only applicable when you put a vid on DVD. Which again, and for a million other little reasons, leads me to think that technology is a bit more complicated than it has to be.

Plays freaking awesome on my iPhone. Must say, I've watched it 3 or 4 times on the phone. Having ready access to that video is worth buying the flawed phone and changing carriers.
I even forced DaH to watch the whole thing again on the phone. Se says "Wow- yeah, that's WAY better than on the 17" computer screen" She can be a sarcastic bitch sometimes. It's why she's so fun to be around. (Oh, and her hotness too...) But seriously, it works fine for me McNally. |
