How to move mask paths over several keyframes all at once?

[Hanker Wanker]

Just wanted to say, that the explination of the problem was totally clear and it seams like Dave understood it perfectly on his first attempt.
The solution he gave however just istn’t working. He clearly didn’t test it for him self.
This is definetly a basic feature missing in AE.

I reached this post because I have the same problem, which is well explained, but I think the solutions you all have given are correct too. I’m attaching a video to explain it better, because I think just a few hours ago I was editing the masks selecting all the keyframes and moving them all at once but now it’s not possible and it’s kind of confusing. Any ideas?

brooke’s method is the only one that is doing what JonZ MarZ is asking about. It seems unbelievable that AE isn’t capable of moving the mask’s position over multiple keyframes simultaneously. (Highlighting all keyframes and using the cursor keys didn’t work for me either, at least not on my 2013 Mac Pro, AE v. 14.2.1.34). I wonder if it did work and broke somewhere along the way.

Thanks for finding the workaround, brooke! I needed it today!

[JonZ MarZ] “I’m trying to pull a mask from a position, but unfortunately the other keyframes doesn’t follow and keep morphing to the original state of the next keyframe. Is there a way to make the keyframe follows my correction?”

I think what Op is trying to do is offset path keyframes. like the Uberkey in Mocha.

the sad news is that in Ae it’s not possible. you can’t offset path keyframes. even if you select multiple keyframes, only the one your CTI is on top of will change. this is on of Ae’s mask weaknesses. especially for rotoscoping. the classic example is you find out after a while that one of the vertices was not in the right place. you want to select a few keyframes and for the change to affect all of them at the same time.. no dice unfortunately.

time to go to the feature request page. care to join me? https://www.adobe.com/products/wishform.html

Hi everyone! Let’s go step by step, from last to first.

The right call is in Roei Tzoref. Is the best example of show how Adobe is wrong or lazy with this issue and how Imagineer with Mocha is right and solved it with the right programming.

The UBER KEY mode.

I use it in a daily basis and it’s GOLD. It offers me the chance to modify ONCE a unlimited vertex points and this to be applied to all remaining keyframes WITHOUT changing all by hand.

By 2017, seems to Adobe had not cracked yet.

This is the issue i think this post is all about, and the goal that Dave LaRonde was not understanding (Correct me Dave if i’m wrong).

[Roei Tzoref]

you’re right Gustavo in everything you wrote ;).

I am trying to advocate for this feature and have submitted a feature request. hope this will get through…

Hi Roei! I’ve written too! Hope it gets addressed ASAP!

Long Live Post Production!

I agree that it doesn’t seem to work — to move all mask keyframes at once (without disturbing position of layer itself). I’m almost sure I’ve done it before!

Brooke’s suggestion worked for me.

[Roei Tzoref]

it’s a workaround worth mentioning for some situations where global transform can solve your problem like scale/rotaion/position of all the keyframes.

you don’t need a shape. simply duplicate the masked layer and use it as an alpha matte. this only solves the problem if some global transform adjustment is required, but the real problem is that you can’t offset multiple keyframes like with any other parameter in Ae.
