    Dynamic link with After Effects workflow questions... (exporting from PPro)

    RuesterProd Level 1

      I have CS5 Master on Win7 x64 pc

       

      I have a Premiere sequence with an AE linked comp in it...

       

      If I am using proxies (created at high quality, not low) or pre-renders (in AE comp), would that have any affect on render/export times in Premiere Pro (or Adobe Media Encoder)?

       

      What is the best workflow for having AE comps in Premiere to maximize export times in PPro?

       

      Thanks all!

          Are you talking about rendering a proxy and putting it back into your AE comp, e.g. on top of the component layers? If so, theoretically that should make rendering/exporting in Premiere Pro faster since you don't have rendering going on in AE as well; Dynamic Link is simply passing the prerendered frames to Premiere Pro.

           

          Am I following what you're talking about doing?

            I believe that's what I'm talking about, I'm not clear on what you mean by putting the proxy back on top of the component layers, I thought that was andled automatically when you go to create proxy in After Effects, it lays it over the top of what you have, right?

              Umm... sure? To be perfectly honest, I've never tried it!

               

              As it is, I don't think that's the case; you can set a post-render action in AE to import the rendered file back into your project, but I don't think there's an automatic replacement or addition to the existing comp. You'd have to do that manually. But given that, if you're already rendering out a finished comp, why not just import it into Premiere Pro and forget about the Dynamic Link?

               

              A proxy in AE is essentially a low-resolution version of a footage item, not a finished comp. So short of doing a bait-and-switch where you build your comp, render it out of AE, import the rendered file back in, and put it as a layer into the finished comp (on top, presumably, since that will basically null the rendering of the other layers below), I don't believe there is a more straightforward workflow.

                Thanks for your reply Colin,

                 

                Well, the main reason I was asking is that I want to render out layers I will not be changing (for instance A color correction effect over the video portion of my comp) to save time in the future, not the whole comp, as I will most likely be making some changes to the rest. So that's why I was wondering how the Dynamic link reads these.

                 

                I did ended up finding out that rendering and replacing in AE (Pre-rendering) does make my exports faster from Premiere.

                 

                Thanks!

                  Good--it definitely should. You're significantly lightening the rendering load since all the effects, transformations, etc. are baked into the pre-render. As long as you're using a high-resolution, uncompressed or losslessly-compressed intermediate, you shouldn't notice any quality hit, but you will notice the time difference. I don't know if there will be a significant difference in rendering time once its aggregated, but for stuff that you won't be changing or will be reusing frequently, it certainly makes sense to pre-render.
