Openshot-qt: Can't Keyframe Clip Speed (to combine fast-forwarding with normal speed)

[peanutbutterandcrackers]

So, I wanted to have a clip change it's speed while playing and proceeded to mark keyframes in it (not the preset style - because I want some part of the clip to go fast while other one remains the same; I thought Bezier keyframe would give it a neat look/effect); but the clip is just stuck.

I figure it is because only the 'Time' property has changed but the 'End' and 'Duration' property have not and that is why OpenShot is getting confused. If the 'End' and 'Duration' property could be dynamically allocated when 'Time' property is changed. It could probably work. There is no way one could calculate all of the time changes and put it in there manually. It just is not possible.

Also, I am eagerly waiting for frame-by-frame timeline mode in OpenShot.

@DylanC - In light of #1032 and the fact that this one kinda' theorizes something too, can I haz 'bug' and/or 'enhancement' label plz?

[DylanC]

@peanutbutterandcrackers - No problem. Also definitely a duplicate of #1032.

@DylanC - Haha. True. Thank you! :)

As in #1032, I think this can be closed, as it's merely an issue of knowing _how_ to set the Time parameter. (See my explanation in #1032.) There are bugs in the Time handling (See #1819), and the fact that it would be a major chore to manually keyframe any Time effects is certainly a valid concern, but overall the Time and End/Duration processing is working as intended — even if that intended operation is very, very weird.

@ferdnyc - No problem. Thanks again! (Good sir)
