There is slice, but there is no unslice

[Baldvin Kovács]

The razor tool allows me to slice a video. So far so good. However, I realize that I did cut it too early or too late, and I'd like to re-merge the slices, and slice it again. Then I start looking for some way to do it --- I've spent an hour trying to find a way until I gave up :). I think this is somewhat frustrating user experience, I wonder if it was hard to provide a re-merge?

(In the version I first tried the extra-frustrating thing was that undo would undo much more than I wished. Now it is better: it actually does undo only the slicing, although there is no visual feedback (e.g. changing menu label) to make me relaxed by letting me know what exactly undo will do? For example, if I do a slice, then I switch back to pointer mode, shift-click one part, then I do undo, it will undo _both_ operations, the removal of a clip and the slice as well.)

This is 3 separate bugs of course:
- the un-slice functionality (which I care the most)
- undo does not let me know what it will do
- undo actually has a bug when the order of operations is: slice, delete one of them then undo)

You can "un-slice" without having an "un-slicing" functionality.

Slicing does not actually slice. It duplicates the clip and tells OpenShot to end the first slice wherever you sliced and begin the second slice at that same point.
A full clip will start at 0 and end at its full length, a cropped clip will start at a value above 0 and/or end at a value below its full length, 2 clips generated by slicing will be as 2 cropped clips with the "begin" value of the second slice identical as the "end" value of the first slice (plus the duration of 1 frame, I guess).

You can full around the start and end of a clip in 2 ways:
- using the "resize" tool
- using the clip properties (duration tab) , and setting the start and end parameters at the desired values

To "un-slice" a clip, you have to look at the start and end value of each slice (properties > duration). Say that slice1 has begin1 and end1 as duration parameters, and slice2 has begin2 and end2 as duration parameters. You eliminate either slice1 or slice2, and set the duration parameters of the remaining slice at begin1 and end2. This will restore your original clip.

P.S. Corrections:

You are better off if you eliminate slice2 and keep slice1, since slice1 will be positioned correctly on the time-line, not slice2.

"full around": I meant "fool around" (English is not my native tongue).
