    Newbie question on masking in a AE/PP workflow

    bliouxbird

      Hi all,

       

      First let me say that I'm just starting to use AE. I've done everything in PP so far but I think I might have reached the creative wall and need to integrate AE into my workflow.

       

      I'm thinking that what I want to do is a combo of the 2 but not sure which will do what.

       

      This is what I'm trying to do:

       

      Video running on the first layer.

      On top of that I want a black mask so that only a circle of the video shows in the center.

      On top of the black circle mask I want to run other animations, graphics and video that have a transparent mask to reveail the circle of video below.

      It's a music video and the circle maks will run the entore legnth of the video with numerous cuts to both the black mask overlays and the main video belwow.

      As you'll see the screenshot I want the black areas to fil with these other clips in different blending modes..

      How would you do this?

      Thanks for your help!!!

          I've done something similar to this in Premiere Pro by creating a black layer with a hole in it in Photoshop then using that layer on top in Premiere. With the video under it in Premiere it will play similar to what you have in the picture. I'm not sure what other effects you want but this will handle the video.

            Yeah that's kinda how far I got.

            See screenshots.

            I used a Circle mask on a black video frame to create the mask on the first level of video. That works exactly how I wanted.

            Then I was thinking that I could use a mask I made as a Tile frame in a Track Matte Key on the second level of video/graphics I wanted to add to just the black areas.The key is that this layer of video/graphics must be able to play well with blending modes on the black frame.

            I missing something and can't figure out what it is.

              I probably should've posted this in the PP forum but thought AE might be a better fit for what I want to do.

              Any help would eb GREATLY appreciated!

                hope this is what you are looking for I put a black solid layer on top. Then used the elipse tool to draw a circle mask on that layer, put the video layer under it and used the settings in the image.

                Then put the other video on top of the black solid layer and copy the mask portion of that layer and paste it on to the top video layer. Now you should have a video playing on top with a hole cut down to the bottom video also playing at the same time.

                  Yeah that's it!

                  And sooo simple.

                  Gonna go give it a try.

                  I always make things so complicated

                    I have a handle on the process just one little issue.

                     

                    My top graphic layer has been scaled to look how I want it which is larger than the main video dimensions.

                    When I paste the mask from the black solid layer I'm pretty sure it's resizing it to my scaling on the top layer.

                    Is there a way to keep the mask from scaling when pasted into the layer?

                    The first screenshot shows the graphic layer without the mask and the second is what happens when I paste the mask.

                     

                    This project will have a ton of scaling to the 2nd graphic/video layer so I need to get a handle on how to keep my original circle mask sized and positioned where the original one is.

                     

                    I hope that makes sense. I really appreciate your help.

                     

                    If you ever need help with PS let me know!

                      This is for anyone else who might to do this.

                       

                      As far as I understand copying mask between layers is tricky if you scale the layer you're pasting into. The mask will not be the same.

                      There are scripts you can buy but who needs that when you could just...

                       

                      • I placed my graphic/video layers that would need scaling and crazy amounts of repositioning on the first layer.
                      • Then added a black solid layer to that with a mask.
                      • That way I can do what I want to the base layer and the mask will stay where I need it and in the correct ratio.
                      • My video file that wouldn't be scaled or repositioned I placed on the top layer and copied my black layer mask into each layer in the upper layers of the comp.

                       

                      In the end I have a static mask of video and movable, scalable assets under it.

                       

                      I hope this makes sense to anyone attempting this.
