It would be great, that when you change speed of some clip, then all neighbour clips are automatically shifted as needed. So, it is sort of sticking clips together. See this video for reference about how it is done in Final Cut: https://youtu.be/jcmEtxWXy6A?t=1m43s (see from 1:43 to 2:00). What do you think about it? Is it possible to implement in kdenlive?
Seems useful. We already have ripple edit that can shift all later clips on resize, I guess we could make CTRL+resize also work in ripple mode to change the clip speed
