AE 6.5 and Proxies.

[Erik Pontius]

Oddly enough…I found this in the AE help file:

Proxy

Most often a lower-resolution or still version of existing footage used to replace the original to save processing time. Use a proxy when you have the actual footage but you want to speed up previewing or rendering of test movies. You must have a file available to use as a proxy.

Using either method, any attributes and keyframes you apply to the placeholder or proxy are transferred to the actual footage when you insert it. You can even set a proxy for a placeholder, so that you use a low-resolution or still version of full-resolution footage that is not yet available. (See Working with missing source footage and Substituting a low-resolution proxy for footage.)

If final footage is unavailable, and you simply want to substitute draft footage or a storyboard still image, you can import the draft footage and replace it with final footage later.

Thanks for the info. I will look it up in the AE help files, 😛

If I think I’m happy with a hard-to-render part of a composition, I will sometimes render at a final resolution, which still dramatically speeds up the work, instead of AE having to process it again and again while you add items on top… but usually I do low-res versions, just to speed up the work process in general. Make sure and look at your render settings during your final render, to determine if you want to continue using the proxies to render or not.
