I can't seem to be able to reproduce case 1, please add steps to reproduce
I don't use masks really, so I would appreciate steps here as well.

Also please make report for each bug

Please watch the video to reproduce Case 1:

Case_1.mp4

Notes:
See the "moving water" which is "freezing" when the transition:
Adjustment.002 -> Wipe.002

See the "falling leaves" which are "freezing" when the transition:
Wipe.002 -> Adjustment.003

It looks like a lost dynamic of the video!

Please watch the video to reproduce Case 2:

Case_2.mp4

Notes:
See the Graph Editor / Sequencer Preview / Mask (with animation):
An animation curve type cannot be changed when creating an animation of the curve/square/circle mask.
The curve type remains only Constant / Linear!

Have a good day and open new useful features!

Thanks for videos,

In case of transition, strips have to overlap. See example below
transition.blend

In second case this seems to be because result is cached and changing curve doesn't trigger cache invalidation. You can press Ctrl+R to do invalidation manually.
It is valid issue though, and it should be resolved, but it is relatively complex issue to solve and it may require design changes. so I will mark this known issue for now.

Thanks for the answer, Richard!

I have watched the "transition.blend" file -> Your method works! :)
I have pressed these "Ctrl+R" keys -> This method doesn't work! :(
It relates not only to any Curve mask animation, but also to the simple
Square and Circle masks when animating the Scale, Rotate, and Move properties.
The curve type still remains only Constant or Linear when changing to any other one!

Have interesting experiments, and lucky Blender improvements!

Sorry I should have been more clear - you must press Ctrl+R in timeline so the orange line on bottom dissappears. Can you re-check? Otherwise can you upload .blend file so I can have a look at what is going on?

I changed the curve type from Constant to Exponential in the Graph Editor, and then
I pressed the "Ctrl+R" in the Timeline, but the animation of the grey circle has not changed
in the Sequencer Preview, so I uploaded the "mask_test.blend" file for you. Thank you very much!

@Vova12zx Thanks for file, I don't use masking a lot so I didn't see immediately what the problem was.

So far I see that mask shape is defined by discrete keys, visible in dope sheet. Curve in graph is actually link to "expand modifier" button. it has no effect on image.
It seems that mask shape animation can not be pushed into action and controlled that way..

What you should be able to do IMO is to add speed effect to masked strip, and controll mask that way. This doesn't work however... This could be bug or design issue again. Will need to check this

I am very glad that you were able to discover this! :)
After your development checking, If you can fix it,
please let me know... Thanks for the great job!

Looking at this, solution seems to be simple, but there may be problems implementing this without some major refactoring being committed first.
I have patches for this change prepared, but it probably won't happen in current release, only in 2.93.

Thanks for the future improvement! This is a great thing
that will help many animators, using only the Video Sequencer
and a regular image, which will make it possible to better animate
selected areas using a mask, turning a static image into a dynamic one.

Have prosperity and balance in all spheres of life! Merry Christmas and Happy New Year! :)
