Pink ringing on Boris Text with Stretch transition.

[Luke Maslen]

Hi Sean,

Not only is the pink ringing odd but there appear to be all kinds of compression artefacts around the text in your image which doesn’t make sense for uncompressed material.

I would sugget reposting this question in the Boris FX forum. We just use the Apple uncompressed codecs and so this isn’t a DeckLink specific question and you may receive more help in the Boris FX forum.

No the compression is just from making it a JPEG. The imge in the timeline is clean as a whistle.
I am also having another MAJOR problem. Some of my images have the double border filter on them.
If I render them the border disappears! This is a really big problem as I have to deliver this online very
soon. Please help if you can.

Hi Sean,

I’m not familiar with Borix FX but I’ll ask around in case anyone has any ideas. Meanwhile I suggest you repost in the Borris FX forum to increase your chances of an answer.

It’s not just a Boris issue. I think I have found a temporary solution. If I render in 8 BIt all is well. If I render in 10 Bit RGB all looks normal as well. Which would you suggest I go with here. This item is for broadcast internationally.

whenever we use a lot of text or photoshop layers we always work in 8 bit. we have always gotten green or pink edges in 10 bit. this has been going on forever and no one seems to have an answer. sometimes rendering solves it – sometimes it doesn’t. don’t know if it’s FCP or BMD.
i have given up trying to resolve it and just work in 8 bit when necessary.

Thanks. Glad at least to see that I am not alone. I have found that rendering in RGB fixes the problem.
Also the text is over an Animation file. I wonder if that is also part of the problem. I will do some tests just using straight video and see. Oh and this is PAL we are talking about here. Don’t know if that makes a difference.

Just to let you guys know, I’ve had that same problem too.
Mainly on graphics or text.
Normally a pink edge, or a white line on the edge of the graphic or text.
It happens only in 10-bit uncompressed.

My work around is also to change the Video Processing settings to Render in 8-bit YUV.

Would be nice if we could keep it all in 10-bit.

Marco

Seems to be the same problem as my earlier post, https://forums.creativecow.net/cgi-bin/new_read_post.cgi?forumid=124&postid=856063.
BMD have tested this and say it is an Apple bug which they have reported.

OK so what are peoples thoughts on rendering in either RGB or 8 Bit? I would have thought RGB 10 Bit would be better?
