Jello

[John 'twosheds' McDonald]

I used Warp to stabilise a hand held video. It smoothed out the basic jerkiness but it also introduced a jello effect. Imagine a vertical pan and the image seems to sway from side to side about a vertical axis. You can see it here at about 20 secs and there is another illustration at about the 55 sec mark:-

Any suggestions?

Also, as a very new Vimeo user, any suggestions as to why my video is scrunched horizontally?

EDIT: Original 'jelloed' video replaced on Vimeo. Here is the "non-jelloed" version.

With the warp stabilizer the background is analyzed. When there is a pan the background is changing and this creates the jello wobble. The amount to stabilize can be reduced. I think the default is something like 50%. You have to choose between how much hand held shakiness is acceptable vs. how much wobble.

I tried to embed your video in this post and it is scrunched. Not sure why. Ron help?

Well I played with this a little more and it seems that the "jello wobble" effect was introduced when I exported the clip as an .mp4. In the project prior to export the clip does not display that wobble at all.

Now about to try an export in a different format to see if the effect is re-introduced. Strange behaviour!

John, are you using the Vimeo preset in PrPro? I use the 720p.

[John 'twosheds' McDonald]

Well I am stumped. I cannot re-create the problem.

My "mini test project" used exactly the same settings as the main project and everything is as it should be. So I'll just go back and re-work the original project and put this down to "just one of those things." Ho hum...

Cheryl, thanks for the suggestion about Vimeo. I did use that preset but whatever took place it was "further back" in the workflow.

Odd things have happened before in my projects where you can't recreate the problem. The Gaslight effect. Glad things are working for you now.

I went back to the original project and created two new sequences, one for each of the 'jelloed' clips. Then I re-did the stabilisation etc. and inserted the new sequences back into the main project. Problem solved.

Still remains a mystery to me how the problem arose in the first place but at least now it has been corrected/removed.

I'm sorry I have missed this video, John.

You managed to bring the eye to very meaningful points of view: the apse seem to defrag and the marble to become snow.

Sometimes it seems that one can read through the decorations.

It means a lot and it is rarely seen keeping good pace with fast zooms.

Thank you Francesco.
