System Information
win 7 pro 64bit 8GB ram

Blender Version
Broken: 2.70 b66a954
Worked: (optional)

When you add additional Mask Layers in the Mask tool (UV Image editor or MCE), any keyframes created only appear in Dope Editor for the first layer.
This means you can't alter the keyframes of other mask layers.

steps:

Make a new mask
Make a new mask layer and add a mask shape.
Create a keyframe - move in time create another keyframe - keyframe appears in Dope Sheet
Make a new mask layer and add a new mask shape there
Create a keyframe - move in time create another keyframe - no more keyframes appear in Dope sheet.

.blend attached. Disregard VSE strips, look at the Dope Sheet. There should be keyframes on every Mask Layer.

I can't redo this bug, a few instructions aren't clear.

Make a new mask --- a new mask datablock replacing the existing one?

Can you upload a blend where adding a mask-keyframe fails?

I cannot now reproduce this fault.
I found that the issue (of displaying KFs in dope sheet) went away when I re-opened the .blend file. They now add correctly.
Perhaps that is why you cannot reproduce it in the submitted .blend.
I was using the VSE at the time with the mask datablock being referred to by a strip mask.

However
There are a number of active keyframes working on the mask layers provided in the .blend file. You cannot see them in the Dope Sheet. Do they appear elsewhere in a data structure? Why wouldn't they appear upon creation? I guess there is now way to retrospectively display them after creation?

Sorry for incompleteness.
Steps:
Create a new mask in UV image editor while it is looking at the render result. Then add mask layers to this single mask datablock. Add Keyframes. Add mask layers to Mask, then add keyframes.

@davidmcsween, Please could you be more specific, your new instructions are still not clear.

Is this in a new blend file or the one you have provided?
Does this bug only happen with the render result?
You add keyframes and THEN mask layer? This is not going to do anything
How are you adding keyframes exactly?

This is too vague, you need to give exact steps in detail, what key you press what menu etc... and make sure its re-producible.

At this point Im' having to make too many guesses and I still can redo any bug.

I believe that it is part user error and part bug.
Below I have defined the steps.
After animating the mask once I created a new mask layer and DUPLICTAED the original mask.
At this point I thought that I was editing a mask on the new layer, no keyframes appeared on this layer as there was no duped mask there. This was my mistake as I thought I could move masks to alternate layers (not obvious)

However, I notice in the new .blend that the original animation is fails (keyframes remain) after duplicating the first mask. Now no new animation occurs and no keyframes can be added on that layer.

New .blend attached.
Here are the steps:

create 2 color effect strips to wipe between in VSE
render a frame to use in UV image window
change UV image view to render result / open a dope sheet set to mask
change editing context to Mask
add a mask, give it feather (may not be needed)
create a key frame in UV image mask window
move along timeline
move mask, create another keyframe
create a new mask layer
duplicate (shift D) the mask
repeat steps 6 - 8
in VSE select top strip to transition to add a mask modifier, select the mask by name
set strip to over drop
watch effect.

From what I can tell this is a usability issue.


- create a new mask layer
- duplicate (shift D) the mask

This does **not** duplicate the selected mask into the new layer, is that what your expecting?

Yes I did at first, but I understand why that was a faulty premise.

I often want to duplicate a mask shape and its animation, but it seems that doing this corrupts original data.

@davidmcsween

Can you give exact steps to corrupt original data?
