I am working on a kid's music video project, and I'm just wrapping it up. The whole video is shot on a cyc, lit pink.

I've used Title3D to add the kids names to some of the shots. The names are yellow.

Any time the name comes up, the background takes on an orange-y color, and when the name dissolves off, the background snaps back to pink.

This happens everytime I use Title3D.

This doesn't happen in the timeline, only when I export.

Timeline is ProRes422, 29.97, HD. Was shot on a 5D and converted to ProRes using the plugin.





You can see it anywhere a title comes up.

Suggestions?

Does it happen if you change the color of the text?

Under the video processing processing tab, are you set to render in YUV and maximum white is set to "white"?

YUV, yes. White, yes.

I didn't try another color of text (Yet).

"This doesn't happen in the timeline, only when I export. "

i had something like this recently.
vfx work done in After effects was popping to a different gamma,
even though the same codec had been used all along (i think)

the problem was ONLY visible in exports,
and not in FCP

my solution was to go to the QUICKTIME references,
and on the first, General, page,
at the bottom,
tick "Enable Final Cut Studio colour compatibility"

i don't know how this is supposed to work if i'm passing the file around.
and i don't know why it happens.

My bet is on those 10-bit rendering problems that have plagued us for years. I wasn't aware that ProRes would have them, though.

As a test, try duplicating your Sequence, then go into Video Processing and switch to 8-bit YUV.
