Warp stabilizer & slow-motion footage

Question

Hi everyone,I have a serious load of ultra slow-motion footage to stabilize, mostly follow pans. Given it's slomo stuff, warp stab happens to be way out of limits I would need.I understand stab is highly related to movement over time, and slomo gives analyzer to think everything is smooth, while it is only because of the slomo rate.We're talking here of 1 or 2k fps footage, meaning a 1/40 or 1/80 of a standard frame rate.I think the main issue I have is limit of the smoothness parameter. It can't go over 1000%, where I could easily need 5 or 10k %.This setting limit, when divided by 40 (for 1000fps) is only 25%, or 12.5% for 2000fps, which is of course way out of useful range.I've also used the crop less/smooth more variable, but it has no visible effect in this case.May I ask Adobe team any consideration for next update on this module ?Meanwhile, if anyone has a brilliant idea to help here, please be very welcome!Unrelated to previous issue, but still about this warp stab module, I think it would be a very good idea to make analysis & correction data accessible to user, for further editing. I'm thinking here of data we can get with regular tracker, such as anchor, pos, rot, scale… It probably makes no sense when using the warper mode, but would have in all the other modes. As a matter of fact, for now we don't have a cloud tracker that leads to anchor/pos/rot/scale regular editable data...Thanks for readingDavid

Rick, thanks again for your time and expertise here,

I'm actually encoding a typical shot so you can see what the issue is. It will be available in some minutes.

Seems to me that your solution can't work because if I speed footage up, I will need to "unspeed" it later, right ? So if I wanna keep all my original frames heres, I will have to concatenate, otherwise I'll loose some frames. Or is there something I didn't get here ?

What I'm looking for is of course preserving all my frames AND stabbing them hard enough so that when I later speed 'em up by 40, result won't show any vertical wiggle, that could have earlier been "masked" by the very slow rate.

Again, warp stab does an excellent job, but won't judge bad moves on a sufficient time range, so it won't allow me to smooth enough...

In 5 minutes now, you should get here one shot, that is 400MB : Dropbox - CRUCIAL_S001_S001_T009 h264.mov

As previously stated, it will look good at nominal speed, but when played back 40x faster, simulating realtime, it will show very unpleasant vertical wiggle...

I would do it this way with Mocha Ae:

1. right click on on the footage -> track in mocha Ae

2. select a decent area in on the foreground. select only translation in the motion panel

3. unlink the mocha shape from the tracker

4. track

5. if you did not start on the first frame, then on the first frame nudge the planar surface so it will record it as the full frame

6. export tracking data - transform, click invert

7. paste in Ae. now you have a stabilized shot for both X and Y. you will also get scale and rotation and can remove those

8. separate dimensions of X and Y and click on the stopwatch to remove the X movement

now you have stabilized the shot on the Y axis, all you have to do is precomp (for order sake...) make sure you collapse the precomp to avoid a render hit. make any speed changes you need. scale and position it a bit to make up for the missing part of the frame.

Could you please describe what you are trying to do in more detail? If it's so smooth that the Warp Stabilizer isn't doing anything, I don't understand what you are trying to do.

Can you use the legacy stabilizer to do what you're asking for?
