I am reworking an AE web portfolio video with placeholders and putting in my own content. I am new to AE and would like to know how you gauge the exact size of the placeholder image files.
if it's a layer solid or Ae Placeholder then in the project window right click and replace footage and choose placeholder or solid and change the dimensions to your needs. if it's a composition then in the project window go to composition->composition settings and change the dimensions to your needs
I right click and see the composition settings dialogue and the pixel dimensions now. Thanks!
