Can anyone help understand Ripple, Rolling, Slip and Slide?

[Vamp]

I really just can't understand/remember the difference and the use of all of them!

Any help?

You know, I've been cutting video for years , and neither can I ... in fact I've never had to know... just do the edit the way I want. More important concepts to understand are jump cuts, proper use of cutaways when crossing the axis etc....

Well i'm not sure what slip and slide edits are..., but a ripple edit works like this. Say you want to make a clip shorter in length. You select the ripple edit took and put it over the end of the clip...then you click and drag the clip to the desired length and all the clips behind it follow it right along so that there is no gap between those two clips where the edit point is. You know how you have two clips and then you want to shorten clip number one, and you take the razor tool and cut off a little of clip one and delete that little bit you cut off? What happens? YOu're left with a little gap ( or black video ) betweeen the two clips. witht he ripple edit tool you can avoid that because if literally gets rid of that gap.

The Rolling edit tool takes the edit point between two clips and let's you 'roll' it forward or backwards but keeping the overall length of the two clips the same. So if you rolled an edit forward, it would lengthen the first clips and shorten the second.

(When I'm saying shorten or lengthen in the above parts I meaning clipping off or adding frames to the clips. I dont mean 'timestreching' the clips where that would make the clips longer or shorter but is related to speed.)

I'd have to look up again what the slide and slip edits are :/
