Stablization with Imagineer’s Mokey
I have some very grainy film footage that was converted to HD (progressive) 1280×720.
The client wanted to stabilize the shots so I can do some roto and add elements into the shot with ease. They were “locked off” shots but still wiggle back and forth a bit – not because of the telecine.
I attempted it in AE first, but failed miserably as the grain was too much for the point tracker to handle.
I then attempted it in Mokey. I can only seem to find one tutorial on how to accurately stabilize in Mokey, so I attempted to read the manual and go for it.
Here is the problem:
In Mokey the stabilization seems to work really well and the image seems rock solid. I can tell because I can see the wiggle of the image and its exposing black edges (not an issue).
The real issue is when I’m exporting the stabilization data for after effects. I’m exporting the stab data for AE position (not corner pin) and copying the text document and pasting it onto a NULL object layer in AE.
I am then parenting the video layer to the NULL (from the first frame).
But it doesn’t seem to have as much “wiggle” and the stablization isn’t rock solid anymore! I don’t see any black edges being exposed like I did in Mokey.I thought maybe it was because I attached the data to a NULL, so I put the data right onto the video layer, but still no luck.
Any help?

Hi Nick,
What I think you’ve done is forgotten to delete the Position keyframes on the null. When you pasted in the tracking data it put in identical values for Anchor Point and Position. This nullifies the effect. So get rid of one lot and you should be good to go.
I’ve made a video tutorial for getting data in from Mocha, the principle should be the same. You’ll be able to find it either on Imagineer’s site or on mine. It’s the Workflow one.
All the best,

Thanks Ben,
I finally figured it out after I posted that question. I ended up doing exactly what you said and deleted all the anchor point position keyframes (and reset the anchor point to its default center).
Do you know why AE users are forced to do this? And do you know if it makes a difference if you delete the Anchor Point or Position keyframes?
Thanks for you help. I’ve been spending hours reading about MOCHA (Since almost all the information I find is about MOCHA) but I’m assuming I can use what I’ve read for Mokey as well.

No problem.
I think the reason that they give you all the information is because they don’t know what you want to do with it. You won’t always use it for stabilization, so it remains a flexible tool.
I don’t think it makes any difference if you remove the anchor or position keyframes if you’re just using it on a null.
Where the Imagineer Systems products share features, the method of working with them is the same, for example, the core planar tracker functions in the same way regardless of application. So a good deal of your Mocha reading would also pertain to Mokey. But there are big differences between applications, and each has their own features and type of job that they are suitable for.
Good luck with it,
