Hi all,
If a video clip contains a lot of interlacing (horizontal lines wherever there's movement), does this mean that the clip's been optimized too much?
Thanks

True, when you encode the video to digital, just activate the de-interlace filter. This should help
Interlacing was "invented" in the 1920's by RCA.
It has to do with just plain old television technology they anything else.
Remember "scan lines" or tv flicker?
A good summary and some examples are at:
http://en.wikipedia.org/wiki/Interlace
Then you have some issues with NTSC (Never the same color twice) US based technology based on 60 hertz and PAL at 50 hertz. Somewhere back in history when they introduced color US brought down the scan rate to 59.94 hertz. (that is why we sometimes capture at 59.94 instead of an easy 60).
Motion pictures (if you ever convert from raw file) is done in 24 fps. For best results slow it down to 23.976 fps and then telecine it.
When you look at all those profiles you can create with encoders and video software you find out there is a lot of history that makes easy of the settings important. We are, in fact, keeping 100 years worth of technology every time we publish a video online.
Isn't science fun?
