To do what you seek, you can create a null object, position it at the clip's anchor point, then parent the clip to the null object.
Use the null's rotation properties to make the correction.
You can also copy effects and their keyframes and paste them in another layer. You can duplicate a layer then replace the footage in that layer with different footage and all the effects will stay in place. You can add an expression to your keyframes that's as simple as value + and a pickwhip to the slider so that all of the values are modified by changing the slider. There are a thousand solutions for this, you just have to pick the one that works the best for each situation.
that sounds exactly like the tip I was looking for!
thank you very much, I'll have a try and post if it worked
Yes, it worked very well indeed. Thank you very much. If I experience a situation I can not handle with the parented null-object I'll try the other tips and report how they worked here!
I found another great way to make it work (even though I'll just use it, when the null-object ect. won't work):
It's called "precomposed layers" and works really well, especially because it allows you to edit compositions that have "time distortion" and "time stretching" enabled. once you have a layer that has some time-relevant effects and want to add another effect (e.g. tracking, or twixtor...), select the layer (or several), use "Ctrl + shift + C" and select the second option. the layer is then replaced by a new untouched layer of the clip. that clip links to the edited original clip (which kind of hides under it).
In PS speech: you merge the layers, but have access to the unmerged layers
I needed it to use tracking on time stretched clips and also in combination with twixtor
