  • Motion Blur for Cut Out Object

    Posted by Eric Goldstein on May 30, 2007 at 2:29 pm

    Hi,

    I have a still image of a cell phone that I cut out from its background. I’m moving it across
    another image as if it’s been thrown. I want to blur it to make it look more realistic, but motion blur is restricted because of the image is cut out and looks like a series of the object repeated rather than a blur.

    Does anyone have any suggestions on how to get a better looking blur in this circumstance?

    Thanks,

    Eric

    you might try a little directional blur. adjust the direction to follow your motion. it shouldn’t take much blur to smooth things out.

    Two things I’d like to note:

    1. As I understand it, AE CS3 will let you choose the frequency of samples for Motion Blur. I haven’t played with this yet, but my guess is that it will increase render time but give much better results in the motion blur department. There was a post about this not too long ago, although I may have misunderstood it and Adobe may have just refined the motion blur method to give much better results… Something to look into!

    2. Linear blending (and optionally 32-bpc) can help give you more realistic motion blur, also at the cost of render time. If you’re not familiar with linear compositing then you might want to read up before you try this, it usually doesn’t work too well in 8-bpc.

    Thank you all for your responses. I didn’t have time to look into the linear compositing, but I’ve put in on my list. In the end, combining directional blur with AE’s motion blur did the trick.

    Thanks again, for the help.
