3d Camer tracker: Layer size must match composition and use default transform values.

 

Okay, this sounds simple, but i cant get it to work!!!!!!!!!!!

 

I create a new comp, and use 1366x745, wich i think was what i recorded and then resized it to in Camtasia.  I then just drag 3d camera tracker onto it, an then POP goes the error!

 

What do i do?

 

btw, i have cs6

    Make it easy on yourself, drag your clip down and drop it on the "Create" icon. It will generate a sequence with the EXACT specs of your clip. Then try tracking again.

    What lasvideo said. Simply drag&drop the footage onto the new comp icon at the bottom of the project window. Assuming your footage interpretation was correct, the comp will inherit the settings correctly.

    UGgg, it worked, but it didnt track the railing that i wanted.  All it tracks now is the background, and it looks dimented cus i want the subject to be on the railing, bu t it loks like they are connected to the background.

    The 3D camera tracker is unpredictable. It tends to work best if the video is fairly sharp with clearly defined areas which represent movement of the environment. It seems to need this to calculate parallax and the camera field of view. If you have objects or people moving in the footage, it can through the camera tracker off. Experiment with the various settings on a small section of the video clip. Once you have settings that work, expand the time range you want to track and re-try it.

     

    I have gotten very mixed results, and find that its simple controls and interface may limit some of its power. When it works, it usually works very well. When it doesn't, the results are useless. Keep trying and good luck.

    I'm thinking of just rotoscoping the railing out and then motion tracking only the railing and add the person, then overlay it on the original footage.

    Ok, i just rotoscoped the railing out and rendered and then tracked the new one, and it says analysis failed.  i think that there is not enough points...
