Removing Objects from Video

Apr 9, 2013 1:43 PM

I have a video of a cat dancing. I would like to remove the arms of the person making her dance, so it looks like she's dancing on her own.

I'm pretty sure I have to use After Effects for this? Would this be considered rotoscope? Any advice for this would be greatly appreciated.

Thanks a bunch

 

P.s. I have included the video in question.

    Yup, AE and Rotoscope.  Won't be easy, though.  You have to do more than just remove the arms, you also need to fill in the new empty space with something, and from looking at the video, I think you'll find the sheer amount of work involved will not be worth it on this project.

    Re: rotoscoping out the arms...

    you have a better chance of finding a real dancing cat.

    Check out Adobe TV.  They have quite a few free videos on various Adobe tools.

     

    However, you don't just need to fill the space with 'something'.  As the arms cover the cat itself, you'd need to 'create' the parts of the cat that are not there for this to look right.  There you're talking about 3D content creation, ala Hollywood visual effects.

    Reshooting would be a LOT less work.

    Training.

     

    Fishing line.

     

    Digital cat.

     

    Animation.

     

    Puppet cat.

     

     

    It's the same question Hollywood has been asking for over a century.  "How do I put my imagination on screen?"

    manipulating the cat in front of a blue screen.

    Lol.  This is the first thing I thought too.  What does it say about us as people?

    Here's a fun look at how rotoscoping has been done in AE over the years...

    http://tv.adobe.com/watch/ae-me/the-history-and-future-of-rotoscoping- in-after-effects/

    And a free (home-made) you-tube tutorial demo:

    http://www.youtube.com/watch?v=ZXlN14wyThQ

     

    Linda.com and some other sites have much more in-depth lessons, but you have to pay for most of the good ones.

     

    It's going to ba lot of work in any case. I did about a second-worth of rotoscoping in a personal project recently and it took me several hours to get it right. So perhaps ask yourself, "Does the world really need a nother dancing cat video?"

     

    Seriously, anything is fine to learn with if the subject intersts you. If you really want to do a dancing cat video, play with that one a little to get the feel of it then re-shoot it in a way that will make it easier to complete, for example:

    1. Shoot with a fixed camera so that you don't have to worry about camera movement in addition to the cat and your hands.

    2. Shoot a seperate shot of just the background so that you can matte it in from behind (or in front) as needed.

    3. Maybe wear green gloves and shoot over a green backgorund (or some other distinct solid color) and just try keying things out and animating the gaps back in with sperate images/video clips. Keying usually doesn't look as good as rotoscoping though.

    4. Got any cat-colored gloves? Maybe some white gloves painted to look like cat fur? Then all you have to take out is your arms beyond the cat's body.

     

    I know some of those ideas sound cheesy and far-fetched, but that's how movie magic was invented in the first place. It's just that now there are many really experienced creativeswith a century+ of advancements, some really high end tools (like proprietary CGI software and render farms), and lots of time and manpower that you probably don't have... so they make it look easy. But if you don't mind the end result looking a less than broadcast-perfect, you can probably get the point across, learn a lot, and have some fun in the process.

    Digital cat.

    I vote for the CGIC myself.

     

    Maybe put the cat's (the real dancing cat's) head onto one of the CGIO's (CGI Orcs) from LOR?

    In limited doses of course. I think you knew what I meant. It's fun to get creative and learn new things in the process.

    Moderator/Staff please delete entire discussion.

    What a shame that would be...

     

    I know your other thread was a cat-astrophe,

    but you have still gotten some solid advice, inspiration

    and encouragement from the fine folks here @Pr Forum.
