Suddenly Rounded crop doing weird things

I don’t use Rounded Crop in Pr 26.2.2 a lot but today I need it and I cannot make heads or tails with it.

When I just use on parameter to crop a side it works as it should. But when I try to animate it weird things happen:

You can see that when animated instead of cropping the color from top to bottom it does in in the center. It’s a blank new project with just color mattes, nothing else. Is it a bug or is it so by design? Because if so it should be fixed, it’s nonsense.

Why am I constantly finding bugs in Premiere just a moment before I need to use certain tools in serious projects that are coming?!

Correct answer PaulMurphy

Rounded Crop isn't like a standard crop effect. It's designed to create a four-sided crop "window" around an area of the frame, then let you animate that crop's size and position.

You'll notice that adjusting the Bottom setting also adjusts the Offset. The Offset controls the position of the crop window relative to the clip. When you set Bottom to 100%, it sets the Offset to -540 (the top of the clip). However, when you add the next keyframe, the Offset resets to 0 (the middle of the clip), which is what's causing the crop to originate from the center.

For a wipe effect like the one in your video, it would be much easier to use the built-in Crop effect. If you want to stick with Rounded Crop, try animating only the Offset value instead.

    Then it’s useless… What’s the logic behind such a realization? The standard crop has now rounded corners, I’d have used it of course.

    Hey there,

    I read your post. I’m sorry that the effect is not working the way you would like. In cases like this, you can make a feature request for an effect that would work better for you. I’d be happy to advocate for such a request. Let me know if you need help doing that.

     

    Cheers,
    Kevin
