    Workflow with pictures

    Level 1
      Hi

      i've got an animation with a lot of images(100) that a camera flies through.

      I'd like to avoid jittery edges on the pictures.Do i need to put on every picture a slight gaussian blur
      or can i just precompose and apply it only once?

          If you want the same amount of blur on the entire image you can either precompose or just add an Adjustment Layer, but use Fast Blur instead of Gaussian Blur:

          If you want to be able to adjust the blur for each image, then you need to apply it to each layer (or even faster: apply the blur to an alpha channel in Photoshop and save as a TIFF, that way the blur is "builtin" and AE doesn't have to recompute it for each frame.)

          Why does the edges get "jittery?" Enable motion blur and if you are you outputting to interlaced viewing such as DVD, you want to add around 0.5 of "Reduce Interlace Flicker."

            Hi Jonas

            Sorry, for my poor explanation but i actually meant reducing interlace flicker.

            So,i can use the Reduce Interlace flicker effect on a Adjustement Layer,right?
            If so,that's great.

            Thx jonas

              Yes, all processing effects can be used as adjustments. Only generator style effects do not make sense to use in this manner (though it may make sense to generate a shape in a pre-comp and use the pre-comp as the adjustment layer...). The specific question for your workflow is however, if applying it to the pre-comped animation would have any noticable effect. It's more likely that you would actually want to apply it to the footage that makes up your 3D layers to interpolate fields and fine lines.
