Object mask issues, Pr 26.0

The following Object mask issues make its use rather complicated:

• Object Mask + timeremapping: when used together without nesting, the mask is tracked at a normal speed, lagging behind or going further from the tracked object:

Applying the object mask and THEN timeremapping brings a visual glitch during the remapped part:

This visual glitch remains even if after the timeremapping you nest it and then track and apply the mask.

• RateStretch + render and replace - object moves inside the cutout, though without rendering the mask is perfect:

• Reversed time and object mask freezes the mask when rendered and replaced:

• Transform + Object mask - object moves inside the cutout (I don’t need to mention that motion blur is available only in the Transform effect). Only nesting helps but in some cases to apply certain effects you have to nest the nest inside the nest which totally ruins the workflow:

The same happens with any other transform effect. But at the same time transitions work alright, affecting both the clip and the mask.

• Alpha glow does not affect the object that was object-masked (or masked at all) - nest is the only way to make it work. At the same time render and replace with an alpha channel does not help either even if you “include effects”. Since you cannot render a nest, this brings a lot of performance issues when you need to use a masked object with heavy effects:
