Can we use different pre-defined mask shapes at different keyframes?

Attached screenshot has 3 keyframes (inside red circle). Can we use different pre-defined mask shapes at different keyframes? Say, rectungular mask at the 1st keyframe, star mask at the 2nd keyframe, and heart mask for the 3rd one.

I tried but it seems only one mask shape can be used for all keyframes.

Thanks & regards.

The simple answer is No. I basically answered this question in your other post. You will need to split the clip to change masks.

FYI you can't directly paste pictures directly in the text box. You either need to upload them to an image sharing site like Imgur and then generate and paste BBC code in your reply, or use the Attachments button below the forum's text box to upload them here directly.

Thanks for the information. Sorry, I forgot attached the screenshot but I attached it now to my original post above now.

It's understood now that we can only use one pre-defined mask shape for the entire clip. One thing to make sure... it seems we can only pan the mask around at different keyframes, but cannot use different sizes of the same mask at different keyframes. If we change mask size at one keyframe, mask size at all other keyframes will be changed too. Is it what we expect?

Thanks & regards.

As your now attached pic partially shows, for a pre-defined mask you can change the Position, Scale, Opacity, and Rotation all independently and uniquely at each keyframe you define for each modification.
