SUMMARY

Kdenlive allows me to change the speed of a video to a percentage of its normal playback speed. However, I quite often would like to change a video clip, not to be 85% of its current speed, but so that it takes the same amount of time as another clip: that is, to make that change visually rather than by numbers. It would be very useful to allow changing a video's speed by dragging it out on the timeline so that I can visually set it to take a certain time to play back. Without this, I have to iteratively guess at percentages by doing a sort of mental version of binary search: let's try setting it to 60%, no, that's too short, hit Undo, try 70%, no, that's too long, Undo, try 65%, too long, Undo, 63%, too short, Undo, 64%, that seems about right. It would be much nicer to be able to drag the video clip to the right length and have the computer do the mathematics to calculate exactly the speed change.
