It's 2021 and you still haven't been able to add something so simple... A key frame option for warp stabaliser
Picture this, you are editing a video, you only want one section of that video to be stabilized, so you keyframe the smoothness to go from whatever percentage down to 0, this gradually bringing the footage back to its original position removing stabilisation. But for some reason Adobe thinks it's better to not add this, instead, I have to cut the parts of the footage I want to be stabilized and then try my hardest to match the dimensions on the next frame based on the autoscale percentage of the stabilizer, But Wait, oh no I've used the perspective method and nothing I do can match the dimensions so now what I have is a shot where there is an obvious jumpcut between the stabilized portion and the unstabilised portion. Now I don't know why you can't add this, I've seen a similar option in mocha Pro where you can select an option so that the footage gradually returns to its original position. It's a simple option and it would make editors lives easier, so can you please stop the rubbish and do it.
