White background in composition window while rendering

[Erik Waluska]

So you’re saying that everything looks fine until you render?

If you are missing codecs then your footage may appear as all white or all black when you try to play it back. I don’t know if this would only appear during render but I suppose that some codecs may have some sort of copy protection that would let you play them back but not render them.

What codec(s) are used in your source footage? If you have any DVC50Pro footage that was exported from Final Cut Pro or a Mac with the FCP codecs then it will not play back on a PC without a third-party codec such as the Raylight decoder.

Can you play all of the footage used in your comp in Quicktime player? You may try to update your Quicktime player to the latest version so you’ll have the latest codecs. If the footage was created with a newer version of Quicktime than what you have then it may cause this problem.

If you can provide more information then someone may be able to help you or point you in the right direction.

No, sorry. I’m not asking about the exported footage rather the actual composition window in the after effects user interface.

If I start a new comp, throw in a solid and render, the composition window’s background stays the same grey as the rest of the user interface.

This prores footage (I have FCP 6.0.6 installed) looks fine, just while rendering the composition _window_ gets a white border.

While not rendering, I see this:

While rendering the window looks like this:

I remember seeing this, or reading about this before but I forget what the white background means.
thanks!

Nope, just triple checked all that. Composition window set to view active camera, comp has one layer, no 3d enabled, twirled transform: “reset”

however I just noticed:
if I render out using animation, no white background.
if I render out using prores, I get the white background.

Can I not render out using ProRes if I have FCP installed? Somehow I feel like I’m going to get slapped for this one.

Thanks!

Thanks Dave, that’s how I actually made this one. I did it again just to make sure I didn’t get click happy somewhere and they are identical.

So, I’m gathering there isn’t a general meaning for this white background?

well nuts.. OpenGL is not enabled.
Thanks for your time Dave!

Anyone else seen this crazy white background?
