the stitch option is only available if the 2 clips to be stitched together are from the same source clip in clip bin
a single clip can be cut/stitched, then un-stitched, then re-stitched
but 2 different clips [A & B], when adjacent on timeline, cannot be stitched together
Some additional information:
If you do indeed have clips from different sources, you can still group them together - just not stitch as Kayakman mentioned.
Also, if they are from the same clip, make sure they are indeed actually butting up against one another. Even a little space in between them will disable the option to stitch.
Finally, one other instance where stitching would not work is if you were trying to stitch media that had clip speed adjustments applied. Again, grouping might be an option in this case.
Sorry you had trouble. Can you let us know how this all played out?
However, you could select "both and/or Multiple" clips at the same time. Right click them and select "Group".
Then you can apply animations that effect the entire track. You can even apply animations across the adjoined clips.
I grouped, intuitively, when trying to stitch two clips. But the tutorial on stitching claims that it IS possible to stitch two separate clips together. Specifically, it says to highlight the two and then right click. So it seems to me that if they can do it in the tutorial for 8.1, I should be able to do it in 8.6.0!
There's absolutely no reason to prevent users from using features you've already built. Can't believe you probably had to *add code* to restrict stitching to just specific cases.
