classic stabilizer won't track thru transitions

Unlink the perspective similarity and translation stabilizers, the classic stabilizer on the color page will not track thru edit page fades or transitions. I love the flexibility of using all these types of stabilizers, so I need ya to tackle that DR!

Stabilizers are a node effect per clip. Stabilize both separately and then add your transition. How would it calculate two shots that need different types if stabilization while transitioning?

Maybe I wasn't clear. So I'm saying that the translation and perspective and similarity types of stabilizers will also track the portion of a clip that belongs to a transition. So if I have a 4 second clip and add a transition, DR will track both the 4 second clip and the additional portion that the clip has been extended when I added the transition - so perhaps the 4 second original clip gets tracked for 6 seconds in total. BUT when you use "classic stabilizer" DR will not track this additional portion of the clip that was extended when creating the transition. I would love for the classic stabilizer to also offer this tracking during the transition extension of the clip.

You can't stabilize-track during transitions because too much is changing. My advice would be to remove the transitions, track the individual clips (with handles), then restore the transition, and now both sides of the transition will be stabilized.

I have situations with film restorations where a baked-in transition resists stabilization for this very reason. I wind up having to chop the film into segments, stabilizing each piece, and sometimes adjusting each frame by hand when necessary. More complex restoration software like MTI DRS Nova and Diament can do stabilization like this, but they're slow and very expensive ($10,000+).

What he wants to have happen, I think, is for the original clip to be stabilized before the transition is applied. But the problem is that when you take a clip and apply a transition like a cross dissolve, there's extra footage in the clip that becomes visible.

For example, if you have a 4-second clip and you add a 1-second transition between it and the clip that follows it, you get an additional 1/2 second after the 4-second mark where the clip is still being faded out by the transition. If the clip was stable up to the 4-second point and then starts gyrating halfway through the transition where the clip has been extended it will look pretty jarring.

As a workaround, I wonder this would work: put a longer version of the clip in its own "stabilize" timeline, stabilize it, set the desired in/out points for the "stabilize" timeline and drop it into your final timeline where you could then add the transition.

try "view current clip with handles" then stabilise. set your handle amount in the settings to as long as your longest transition.
