Upconverting HD Proxy Comp to 4K Comp?

Hey!  This one is a bit convoluted.   I'm starting with 1080p Proxies from Avid to make graphic montages in After Effects..

 

- I need to finish these in 4K with the final 4K EXR files.  So I can't just relink to the 4Ks.

- Some of my comps have up to 80 video, mask, and text layers

 

Is there a plugin that makes this easy?  A plugin?

 

- What I had been doing is

-- Precomp each video layer, drop the 4K into that layer (which is just 1080p) but check the Continuously Rasterize box so that when it's scaled up it retains its quality

-- Precomp the main comp, resize it to the 4096x2048, and then in theory it all gets scaled up and maintains full quality (because of CR turned on).

 

But this is a time consuming process.  There's got to be a better way!  Any ideas?

 

Thanks for your time

The way you're doing it is probably as good as any.  If you have the skills yourself, or the time to commission someone, you could get a script written that automated the process somewhat.  

 

Preparation at the start would have solved the issue for you.  In this kind of job, I'd work in 4K from the start, working in lower preview resolutions most of the time of course.  

 

If you have the 4K files from the start, import them into AE then set the proxies within AE.  Then it's simply a matter of turning off the proxies when you're ready to render.

 

If you don't have the 4K originals from the start, you can work with substitute comps, not unlike what you're doing now.  Import the 1080p proxies, precompose them all in their own comps (just drag them all to the new comp icon and select "Individual Comps" when prompted).   Then change the comps to 4K, and set the appropriate 1080 proxy for each comp.  When you're ready to render, either replace the comps with the 4K master files, or reset the proxies to the master files and activate "Render with Proxies" in the Render Queue.

Thank you, Andrew that's so helpful.

 

I totally agree (in retrospect) it may have been best to start from fake 4K, or "substitute comps" with precomposed HD to 4K to help me on this back end. 

 

I don't have access ot the 4K - it's actually footage shot in 8K that we're luckily only delivering 4K EXR.  SO regardless, I only have the HD to work from until we pull the EXRs at 4K.  And it's such a rushed creative process that I have to be able to work with the plates immediately, ya know.

 

I'm going to try that fake 4K with the upcoming comps I'll be doing.  I'm not sure if it'll slow down my creative workflow, working in fake 4K or not.  We'll see... 

 

But all very insightful information, I really appreciate your thorough response!
