    Guys, I really need your help.

    I would like to create a short (5 min max) video of the following:

    Imagine a piece of a bedroom wall with a a few postcards (say 6) tacked on (like you see in teenagers bedrooms), except instead of still images, I want these postcards to be little video snippets. So…

    1. Handheld camera
    2. One continuous shot, we go from a full shot of the group of postcards on the wall, and then we zoom/pan to view each one individually. End.

    I plan on using After Effects for the compositing.

    Deadline: Sunday Evening/Monday morning.

    I’m off to buy brightly colored paper to make the alpha keying “postcards”, but tell me, is it possible or am I insane to try this with the time available? I imagine there will be a lot of motion tracking and track matting to do, and I am kind of new to that.

    It doesn’t need to be perfect, I just want to get the general idea without it coming off chessy looking.

    Thanks in advance everyone 😀

    I would imagine that you don’t even need the colored paper. What if you have 4 tracking points that’s continuously in the shot. So, as you zoom in on the wall and finally rest on the 4 trackers still in frame.

    Next, you do up your video wall in After Effects, precompose them into a layer, track the 4 trackers in the footage, and apply the match move data into the video wall. Apply a little drop shadow and it should look like post cards plastered on the wall.

    Don Lim,

    Thanks for the tip, but I’m having a hard time figuring out how that would work. For example, how would I go about setting 4 tracking points that always remain in the frame?

    Would you mind breaking it up a little more for me?

    Thanks!

    Anyone else care to chime in? 🙂

    Have you considered, maybe building the entire shot in After Effects.

    No Video. No Tracking.

    Import a Hi Res photo of your room, layout your post cards and add a camera.

    Using vanishing point may be cool if you’re room isn’t too complex.
    I recall a pretty rad tutorial about how to use VP on either this site or videocopilot.com

    You’ll have totally control all of the time.

    Add some wiggle to the camera’s properties to get the handheld effect.

    You’re vision may be too complex for this solution….but I figured I would through it out there.

    good luck.

    Jason,

    Interesting idea… Hadn’t thought of it, and might be a time saver in some aspects… I will look into it!

    Thanks a lot!

    And keep sending those ideas. So far you’ve been a great help.

    Here’s a simplified picture to describe what I meant:

    The high-resolution image idea will work very well if there’s no table or bed, or anything with certain depth in the foreground, else there might be a shift in perspective where you can’t replicate easily in After Effects when you zoom in.

    Don, I’m having trouble getting that link to work. It gives me a “Operation Timed Out” error… Could it be Imageshack is down?

    Yeah, imageshack might be down, I’m having trouble loading that image too. It was fine just now. guess it’s just not meant to be. Anyway, I checked out the vanishing point thing in After effects. It seems like a pretty cool feature.

    Here’s the tutorial in creativecow. Maybe it might just work! search results

    Definetely. I haven’t even yet tried the Vanishint Point feature, but just using a photo of my wall as a 3D object in AE and layering the videos on top is producing wonderful results.
    Thank you guys so much, I have a feeling this is going to work!
