Yeah that happens alot in video. Being a film major i know alot about all this stuff. Especially since I shoot with HDSLR cameras and I have to keep the backgrounds and clothing in mind in order to avoid aliasing... There are plugins for NLE programs (non-linear-editing) like final cut pro that would allow you to get rid of minor aliasing but heavy stuff u can't really deal with... please note too that aliasing doesn't have anything to do with the resolution of the image, i.e. 1080p or 720p.... it has to do with how the camera itself compiles the image..
This is completely off topic, but I think you might be able to answer a burning question that I have not been able to get a logical answer to, and I have asked many people this same question.
Sometimes I get video clips from TV producers who need timecodes inserted in a Word-formatted document. They need the hour, minute, second, and frame.
So, for example, the timecode would look like this: 01:48:21:18 (1 hour, 48 minutes, 21 seconds, and 18 frames).
My question is this: What in the world is so damn important about those frames? If there's, say, 24 frames in 1 second, why is it imperative to have the *exact* frame referenced when a person begins speaking? What on earth could be so different from, say, Frame No. 16 and Frame No. 18 when there's 24 frames in 1 second?
Do the fames have any other function other than there's 24 of them in 1 second?
