I simply can't put a rendered image with a vdeo footage at same time in my 3dstudio.I do it in the preview,but the quality of the logo is not ok 'cause it's not rendered.Tried to mask it in the After ,but didn't work out.Heeeeelp : )
What format are you rendering from 3DS? Is it a format your editor can handle? Did you try rendering from 3DS into a pooular video codec such as a MOV file or AVI?
Try render your 3d animation in TGA Sequence format creating a sequence of tga file in a new folder. In AEF import your footage video and your rendered animation. To import rendered animation be sur to click on TGA Sequence on import time. AEF will ask you about alpha mode to import, select straight option. Put in timeline the footage video and the rendered animation. The compositon is complete.
