Eraser Tool

[Roland R. kahlenberg]

When the Eraser (or any Paint Tool) is selected, the Duration pop-up menu allows you to select the duration of each stroke that you input. Select the option that best meets your needs.

You can also see and modify the extents and durations of paint strokes by selecting a layer in the timeline and revealing the contents of Effects > Paint, or by using the shortcut PP (select a layer and quickly press the P key twice to reveal its paint strokes).

Thanks Walter ! 🙂

When I go into this contents of Effects > Paint, how can I then see, which painting or erasing belongs to which frame ? For example, if I am in the timeline on a specific frame and I need some adjustings to my erasing on this exact frame, then how do I know which of all the listed erasings (in my case 150), is the one that belongs to my specific frame ?

Thanks Dave 🙂

In my specific case, I have rotoscoped a persons arm and then later I see, that the rotoscoping could have been better. So I wanted to fx. zoom in to the fingers and make some adjustings with the eraser.

I guess, that it is possible to go into the effects control and adjust a specific rotoscoped area in a specific frame, but I don’t know how to do that yet 😉

And also, is it possible to use the Pen Tool for erasing ? When I try to do this, I make a mask but then I don’t know if I can somewhat “erase” that selected are.

Thanks for helping 🙂

Hi Dave and thanks.

I guess this is the same as with the erasings I mentioned, I mean where You go into the Effects < Paint and choose the exact paint listed and then correct it ? Is it the same way You correct rotoscoping ?

The problem is I still don’t know how to find out, which of all the listed erasings/rotoscopings (in my case MANY), is the one that belongs to my specific frame ? And furthermore how to correct these.

Using the Paint tool is not a good workflow for roto. It will be a ton of work and almost certainly lead to bad results (chattering edges).

Start here:

An oldie but goodie:

Also consider the Rotobrush tool, which helps automate rotoscoping (but which isn’t perfectly intuitive and will require you to read up a bit):

Thanks for the links Walter, I will definitely look into them.

And thanks also for Your comments Dave.

I have rotoscoped what I wanted, but now afterwards I see, that in some particular frames, it could have been better. Therefor I was looking at the Eraser tool. I still don’t know how to make changes to the rotoscoped frame afterwards, so I’ll look at those links now and see if I get it 🙂
