I've been trying to find a script for this or an easier way to do it, but I couldn't find anything, hence why I'm here!
So I do a lot of 3D compositing in After Effects, where I work and manipulate multiple render passes for each clip.
Usually, I have multiple 'takes' of one 3D scene, where lighting, grading, and compositing are exactly the same, but the cameras/animations are different - this means that in After Effects I usually end up copying a composition with all its effects and layer structure, and then replace the footage in the duplicated composition with a new batch of source render passes.
E.G. in 'Comp 1' I use footage "render_1_beauty, render_1_reflection, etc". Then I duplicate the comp, make it 'Comp 2', and replace the footage in it with "render_2_beauty, render_2_reflection, etc". Of course ultimately I tweak each composition for minor details and adjustments, but the general structure is usually the same.
What happens is because I do heavy compositing, the amount of footage that I have to replace is insane! And what I currently do is basically 'Alt-drag-replace' every new imported render footage whenever I duplicate the composition.
IS THERE AN EASIER WAY TO DO THIS? Maybe an automatic 'template' maker for composition structures, where you can easily point at a composition and it's layers, and use it as a 'preset' when making a new composition, thus all the adjustment layers and effects stay, but the source footage are instantly replaced by another batch.
I was also thinking of maybe making my own script for this, but I honestly wouldn't know where to begin hahahhahaha.
I hope I am clear! And I hope someone has an answer to this 😄
Thanks in advance!
Thanks for the find! I will check it out, doesn't do exactly what I want, but a great alternative!
Hey, there are few things to clarify here, in order to help you out:
I don't think you need any complex tools, unless answers to above will specify otherwise.
To answer your questions:
1. Basically when I have a render sequence fully rendered from my 3D engine I will import all the passes as separate clips into AE. See image below:
2. No that is not true - usually, my names are structured as "render name_Pass type", as seen in the image above.
3. Not necessarily - sometimes I don't use all the passes that I render in my comps - however usually the newly imported assets do match the previously imported assets in terms of what types of passes.
4. I would prefer if it was manual, as there will be exceptional moments where I will have a totally different set of render passes for a completely other scene.
To be practical, It would be nice if I could select an existing comp that I already edited, select a new set of imported assets in the project manager that matches that of the current comp, then click a "duplicate comp" button, and an entirely new comp will be made, where it will automatically replace all layers in the new comp with the newly imported assets that I selected. I made a screenshot below to try and explain the visual workflow. Hope it's clear!
It's been a while since this problem, and after some months of getting into scripting, I have finally managed to make one, and it works like a charm! 😄
My script basically allows render layers in a composition to be replaced by a new batch with names that hold matching syntaxes, EG. 'Render 1_Beauty.exr' will be automatically replaced with 'Render 8_Beauty.exr' as it recognizes 'Beauty' as matching syntax.
This script helps me so much in saving time whenever I have to produce base compositions with similar render/grade quality. It also automatically adjusts the timeline to fit to the length of the replaced footage.
If anyone is interested, let me know! I am curious how much demand there is for this - if so I wouldn't mind officially publishing it 🙂
