Question

How do I remove a rotating display stand from a video while keeping what is on the stand intact?

So I am creating a video for one of our networking products.  I have the product on a 6" electric rotating base.  The product itself is a 3.9 x 3.9 x 1.0 in. (99.8 x 98 x 25 mm) rectangle.  I've tried to to use the Clone Stamp tool in After Effects, which works partly.  The problem is that because the device is rotating i cannot completely remove all of the display stand or i risk parts of my product being masked or removed as well.   I'm a novice but i can follow direction with the best of them.  I also have access to adobe cloud so if there is a particular program in the adobe suite i would need to use other than After Effects please let me know.  I'm scouring the internet but so far i have not found anything that will really work in my situations.

Thank you

Carl

      Doing a small vid for you, Hold on a bit plz

      Easy object to mask and keyframe:

      No need IMO to Roto at all

      Here are the steps:

      1. Create a solid and call it clean  plate

      2. Add a gradient ramp. Change black to colour of your whit by eyedropping

      3. Create mask around the object using points only at edges

      4. Keyframe (do NOT keyframe 1 frame at a time). Use increments of roughly 10 frames or so (so mask does not move around too much

      5. Add the loop expression as per Rick's post

      All done

      Rick Gerard​ This is an easy one as his BG was kinda clean and his object was angular so no need to root at all

      imeilfx​ check the GIF export hehe

      Please note I did this really quickly (like 5 mins) and didn't spend time on refining mask expansion or adding a feather which will give u a more precise look

      Hope this helps

        Since it's your product, it's much simpler to just reshoot it properly with a pedestal.

        Glue a short thin rod to the turntable (e.g. 1cm wide, 5mm tall), cut a hole in the backing material just big enough for the rod to pass through, put the turntable underneath then stick the product to the rod. Then the product will appear to be sitting directly on the floor while it's rotating.

        The less-simple option is to paint everything green and chroma-key out the turntable, but then you lose the shadows and have to deal with spill.

        Dave,

        That is something I was actually thinking about seeing as how using RotoBrush is very tedious work considering 30FPS and 53 seconds. 

        Thank you for the suggestion

        When you do roto work you should have the same frame rate for the comp and the clip. That's really the only way to keep things lined up.

        I took another look at your footage and the best approach for me would be hand roto with one master subtraction mask and two triangular add masks. This took less than 10 minutes and just a few keyframes. If you are interested, here is the project file: Dropbox - Roto.aep  Another 10 minutes or so cleaning up and fine-tuning the mask position would eliminate all but the white disk the product is setting on. Here's a screenshot with everything I did showing.

          Please post - if taht is not a problem - screenshot (or short vid) of your clip and show us what you wish to remove/hide and what you need to keep. Maby there is a way to help you but you have to keep in mind that AE (and other Adobe software) seems like magic CSI piece of machinery, and sometime it works like that, but there are limits depending on kind of footage you use, frame composition etc.

          Hi

          Thanks for responding.  Sorry for the delay I didn't have my work computer with me on Friday and I was out of the office.  The link below is for the video clip I am working on.  I understand I am hoping that there is something i can do in Adobe.  If the base cannot be removed due to how the product is rotating if there is a way to at least removed the power cord that could work as well.

          Thank you Again

          Carl

          Study up on Rotobrush. That is probably the most efficient tool for the job.
