Please describe the need for the feature:
When marking up a video, I sometimes want to vary the speed of the video with time. For example, I might want to play the first 2 seconds at 100% speed, the next 2 seconds at 50% speed, and the last 2 seconds at 80% speed. This would be useful for producing clips where only some portions need additional slowdown or speedup for emphasize or abbreviation.
Please describe the feature and its ideal implementation:
[x] When a marker pair editor is open, I would like to open an additional editor for the time-varying speed which shows a chart of the current mapping from video time to speed.
[x] The time-varying speed editor would ideally allow drawing of the time-varying speed with labelled axes guiding the drawing.
[x] The time-varying speed editor should allow zooming and panning for precise mapping.
[x] The current time of the video should be displayed, perhaps with a vertical bar, in the time-varying speed input chart
[x] The current auto marker pair speed previewing should automatically preview the time-varying speed as well.
~An input box for reviewing and adjusting the specified time-varying speed with greater control and precision.~
Please describe any alternatives you have tried or considered:
The only alternative to this is creating multiple marker pairs, setting their speed individually, and then using the merge list feature to put them together. This is inefficient, error-prone, and not well-compatible with the current previewing features.
