How to set “reagion of interest” precisely?
Hello. I am using AE CS6 win version.
Right now I am trying to make a movie, whose size is 640 x 480(4:3 aspect ratio).And I am editing a composition whose size is, 1024×1024, 1k resolution, and I want to make a proxy of this 1k compositon, but I want to make the proxy size 640 x 480. The reason why I am editing 1k compositon is because it’s easier to make a movie if there is larger space in compositon.
So I need to use region of interest to crop the original 1k composition, but it’s time-consuming to set the region of interest manually. Do you know how to make the region of interest precisely? I thought I put the 1k compositon into 640×480 compositon and make a proxy movie from it, but it means I need to make a lot more compositons to make proxy. It will make my project panel messy…
Thank you in advance.

I really, really don’t recommend this workflow (though it’s a clever workaround for Ae’s restrictive viewports). Use a 3D view [link] instead.
That said — you can’t use numeric entry for the region of interest tool (though the Info panel will show you the ROI’s bounding coordinates).
You can use direct numeric entry in the render queue. Add your comps to the render queue, then click on the output module. Enable Crop, and enter the values as you like (192 each left and right, 272 each to and bottom for a center crop). You can save this output module and re-use it later.

This means that there is a lot of blank space in your composition.
What I understood from your method is that you want to make a proxy of 1k resolution comp with a resolution of 640 x 480 and there should not be any blank space(that’s why you are using Region of Interest to crop the blank area)?
Am I right?
If yes then in render queue, Choose Best settings and then go to Output Module settings.
Now check Crop option and enter the values as shown in the image:

I might suggest another workflow for your situation. Create a “Final Render” composition at the 640×480 resolution and place your working comp in it.

Thank you for your advice guys. OK then I will use the crop option.

I agree with Dave, you’re better off nesting the comp in a render comp of the desired dimensions.
