I want to render a PNG Sequence in black and white. How do I accomplish that? When I try to change the setting the Black and White option is greyed out for me.

Without knowing more information I can't necessarily tell you what your specific problem is. However, I can give you a work around.

If you want grayscale: create an adjustment layer at the top of your comp and use a tint. Then export the sequence as PNG.

If you want a true B&W only, use a threshold and adjust the amount.

Thank you for your answer!

I'm using AE for editing still images (since I don't own PS) of documents scanned in B&W. So my source files are B&W PNG files, but when I want to render them as a PNG Sequence the B&W option is greyed out.

This causes me problems, because when I scan a document the result is binary, i.e. the text is 100% black and all the surrounding area is 100% white. This is ideal for OCR and printing, and hence the way I want my rendered files from AE to be.

But even though my rendered images from AE are in B&W, when you zoom in on the text you can see that AE has added a shade of grey to the text, making the edges of the text softer and a bit blurred. That is bad for OCR and it will use up more ink when I print.

So I want to keep that binary, 100% B&W quality on my images, and I also want to know how to activate the greyed out B&W option, because I think that that would rectify the problem.

Thanks again for taking the time to help me out, and please let me know if you need further details.
