tracked magic masking disappear

I noticed that when I copy a clip with Magic Masking layers to another timeline—or even within the same timeline—the Magic Masking disappears.

I believe it didn’t used to be like this.
Is it somehow losing the effect cache?

I believe this is not new to v20 based on reports from others over the years.

I've also noticed that tracking isn't shared from one user to another when working in a cloud project. When a new user opens the project after the AI Magic Mask 2 has been added to a clip and tracked by another user prior to the new user joining, the clip needs to be tracked. If used extensively in a project, this can get tedious. Given that the new version of Magic Mask is so much better and faster and actually plays back on systems like laptops, it is actually likely to be used more extensively.

I can confirm this has always been this way.. it's really not useable. Use Final Cut Pro's magic mask and you will be like Wow,,

Magic masking is so amazing that you can be tempted to put it on every clip to make sweet adjustments....however...I have also experienced the pain of having dozens of clips that need to be retracked and it isn't always obvious why.
For example, if I "duplicate" a timeline where literally everything is an exact copy, why would I need to rerender all of the magic masks? It has caused me to think twice about heavily relying on this tool because I know that all of my clips might suddenly require rerendering which can be time consuming.

This topic of magic mask has been covered to death on the forums at least dozen times over the years and users should really learn how to use the tool before posting about how its not working. Or at least read the manual and search the forum . Its always worked this way, there are reasons why it works that way, it not an issue unless you make it an issue as a user with disregard for how things work in resolve. I never have the issue with the same tool, simply because I use it correctly. I have also written extensively on this topi, and you can find information on the website. It is not a problem unless you make it a problem.

Magic mask is a color page tool relying on source to remain as it was when tracking was done. Apparently this is impossible for some users to accept. If you protect the source no issues. If you follow appropriate workflow, no issues. The only issue is when people disregard the workflow and invalidate the tracking data by their own action.

In regard to duplicating timelines in particular. If you actually duplicate timeline, magic mask will also retain the link. if you copy and paste the timeline, which is not the same as duplicate option, you will invalidate the link, because it is treated as separate timeline. Right click on the timeline and choose duplicate. Don't copy and paste the timeline if you wish to actually make a duplicate and not a new version with no links to original. Which is what you get when you simply copy and paste it. You could copy and paste the timeline to a new project, while duplicate operation is controlled process with links retained.

Resolve is a complex software with lot of powerful features for lots of differnt users. I don't generally find pointless decisions by developers, which seem to know what they are doing. Users should do the same and read the manual and understand the nature of operations being performed and than software does working quite well. There is room for improvement, but I would suggest to all users that when they run into something that doesn't work as they expect or understand it, they should assume its there for a good reason, not random one.

Just "duplicated" a timeline. Did not alter the clips in anyway. Hit Render and 7 clips needed to be retracked by magic mask.

You are doing something wrong. Works fine over here. I can make it invalid when I want to or not invalid when I want to. It doesn't happen randomly. There are rules. If its not working on your end, I'm pretty sure you caused the mask to lose track.

Or… there’s a bug. Hard to believe but they do happen.

aah Erik,
I actually remembered that from another project. It's right, always rerender the ****. a buddy gave me a nice hint. just to go to the 3 dots on the side and regenerate masking for all clips.
and it does rerendering the whole timeline.

Dude, calm down.
No reason to be cocky.
We're here to look for help or to help others — not to be annoyed or to annoy other people.
Gosh, what toxic behavior.
Exactly what you said: "If it's not a problem, don't make it a problem "

Yes people talk about magic mask for a long time... because nothing really evolved lol.
So the topic is still on the table.

I think it would be nice if we could force the Magic Mask tracking to persist as long as there were no changes made before the Magic Mask node. I also think if you copy the Magic Mask timeline, the mask tracking should travel with it. I can see where Node Stack Layers would add an additional level of potential disfunction.

+1 to that

Totally agree!

This behaviour would just make sense

Is saving the file, closing davinci, and then opening with no further edits doing something wrong?
Because I can, with 100% reproducibility, demonstrate create the mask, saving, closing with no further edits, opening with no further edits, and then the same clip I just fixed the mask on no longer has the mask again.
And that's happening to every. single. mask. At least on my current project.
during playing, and with a render, it's fine once fixed. But with a save and exit, poof it's gone.
Granted, this project was moved over from 19, but the project was nearly empty at the time it was converted and the mask has been entirely done in 20. I have yet to test the mask in a project started with 20, which is something I intend to test soon.
But it is frankly foolish of you to not even be open to the possibility of there being a bug in a public beta, where BUGS ARE EXPECTED.

I carefully watched how I created this problem again.

I have a completed timeline on the Edit page. On the Timeline Tab on the Edit page, I right click and choose duplicate timeline.
I make no edits or changes to any of the clips that contain magic mask tracking data.
I go directly to the render page and choose to render.
Every single clip on my timeline (and there are many) needed to first rerender the magic mask tracking data first.
That happened on two different timelines. Fact.
