I haven't used Warp Stabilizer much yet but I see how this can be useful.  I was already wondering about the transition.

You stabilise the entire clip once you have locked down your edit..or you make a stabilised DI of that clip.

I do not understand meaning of this though..

...and that means you have to have a cut at the beginning and at the end, which might mean you have unwanted cuts, or to preserve the cuts in a longer clip, you might have to stabilize unnecessary frames, which takes time, cpu cycles, and reduces the efficiency, effectiveness, and quality of the part that was stabilized.

I think a tripod is the more effective solution here.  (Or at least, more practice shooting handheld.)

Well I agree with that it's best to get things right in the field and decry  "meh, they'll fix it in post" attitudes, as a documentary editor there's been some footage I've received that's been awful quality but amazing for the story. Story trumps everything. It's nice to have tools that can smooth the edges out on some of that rough footage, rather than imagining that everything will be shot right the first time.

The first thing I tried to find when applying Warp Stabilizer was how to keyframe the level, and was surprised to discover that it's not possible.  It's a great idea, and would be a very useful feature. I have a shot with a nice long pan that I'd like to stabilize, but at the end of the pan, the camera turns abruptly to look at someone.  When applied to the entire clip, it also tries to stabilize through the ending camera movement, which it can't help but fail in doing.  It'd be great to be able to keyframe the smoothness to drop down to zero (basically, have it not stabilize at all) over a few seconds before the end of the pan.  I stabilized the clip and then cut it back into the original, but it's near impossible to match the position and warping of the original with that of the stabilized version. 

So yea, my vote is in favor of keyframes.  Hard to understand how someone couldn't see the value in that. 

The first time I used Warp I hade a video that was only slightly shakey. I could have left it alone, but I really wanted to make it as smooth as possible. But there was this one section where I was jostled a bit. I wanted to keep that part instead of cutting to b-roll (which I could have easily done), but there was no way to properly stabilize it. So, let it shake. Why not? You can see the person who jostled my elbow as they pass by. It isn't like people wouldn't know why it happened. It would almost be modern in that a lot of shaky camera shots are included in movies nowadays.

But, when I cut just before and just after that moment, to avoid stabilizing it, I had a major task on my hands getting it to fit into the video on both sides of it. I was able to use the motion effect to do what I needed to do manully, but if I had been able to keyframe Warp out and back in it sure would have been a big help.

One can always trim the comp to stabilize a protion of a larger clip but of course it won't ramp.

Me Too. God i sooooo need keyframes.

Its such a pain having to cut and slice just to send bits to warp stabilizer.

I did find a useful trick for those that dont know (and for me as in 6 months i'll have forgotten!)

Send your clip to AE, use the warp stabilizer, then
in project window drag your Comp on the New Comp icon and voila!
you have a new comp "a precomp" where you can apply other effects (like fix some of warps changes)

Why this isnt explained clearly and simply on Adobe Help pages i dont know.
