It's the editing of live broadcasts. Editing and airing CNN would be a good example, having to put on all those overlays, have segments ready for playback, switching from news caster to news caster, comercials, switching to live feeds from the Crapistan insurrection, ect.

( i could be way off here)

i think realtime has something to do with the fact that you don't have to render to see it as its supposed to be.

or my stupid guess will be realtime as in what live tv shows do where its all done "in real time

" where when we make an AMV we can stop the source, play it back rewind it and what not.

(again these are just what i've derived with either some form of common sense and or have heard it said before this is by no means concrete fact.)

real time editing

if i get it correctly is when u can add things into video that is being boardcasted live;; like when i broadcasted annoucements on fiber optics at school i could add in effects, titles, and green screen effects straight off without having to re-render the footage

I think real-time editing also means when edited video is played back, it is shown in precise accurate time as edited, without having to create previews(render the video). Pretty much DrngdKreationz's first answer.

I suspect you guys have it pretty much right on. In the CG world, each image (each frame that is) must be rendered. If it is "real time" that means that the frames are rendered fast enough to display the video _while_ it is being rendered. (Or in other words, each frame is rendered while the previous frame is being displayed.)

So I imagine in the video editing world it's the same. Editing in "real time" means each frame of the output video can be rendered while the previous frame is being displayed. The effect: you can watch your output without preredering it as a seperate step. (Note "prerendering" because technically it's still being "rendered", but it is rendered _while_ you watch it.)

If you think about it though, the other comment - that it is when you edit a live video feed - is not incorrect either. If you're editing a live video feed, you can't prerender it, so the rendering must occur in "real time" hence the term "real time editing" is applicable here as well.

That's my exceedingly technical explaination.
So in other words, everyone is right.
