Improving the Speed filter

[brian]

Thanks for your comments.

Seeking into the middle of a clip after speed changes does not bring to the time that the clip would be if played from the beginning. Making precise adjustments can be tedious having to rewatch the entire clip again.

This issue was reported here and is fixed for the next release.

It would make editing easier if the clip length would shorten/lengthen with changes, like how adjusting the speed in properties works.

This was considered during the original implementation. But it creates too many side effects. Will the length of the clip grow and shrink dynamically as a user pulls a keyframe up and down on the filter? What will happen to clips after the affected clip? With they be moved or overwritten? No one has volunteered to tackle all the complications that would come from this.

Being able to make it more than 10x faster would be handy.

I am open minded about this. I chose 10x as the limit because it seems like faster than 10x just looks like a slideshow. If someone needs more than 10x, they can use the speed parameter in the clip properties.

Also, common speed adjustments in the range of 1x-2x become difficult if that range is only the tiny 5% left side of the slider with the right 95% use for less common 2x-20x speed adjustment.

If I take a clip, and cut it up in timeline, and modify sections of it to be faster, it pulls in portions later in the clip, rather than editing the clip as its own stand-alone element. This makes it hard to take a single scene and cut it up and then apply the speed filter to a portion because I have to manually figure out where it should match up with the following clip.

My intention is that you would not cut up the clip. Instead, configure the keyframes in the filter to be 1x speed until the section that you want to speed up. Then, when you are done speeding up, and go back to 1x speed, just leave the speed filter at 1x for the rest of the clip. No need to do any cutting.
