Strange Artifacting Around Text Pict Files
I am getting strange artifacting around my black text against white. I am editing at 10 bit 720×486 uncompressed and am using a pict file for text. The problem isn’t horrible, but slightly noticeable.
Thanks in advance.

If you have moved the text card using the controls in the motion tab you will get some goofy artifacts after rendering when cutting on a 10-bit timeline.

Also could be alpha channel interpretation.

I’m not using an Alpha Channel or moving anything. Just a white slate with black graphics.

Check these things then:
Is your file rendered at Full Quality? (Sequence > Render > Full (dark green bar) checked?
Are you checking the rendered file on a NTSC monitor?Is your RT Pop up showing:
Safe RT?
Playback Video Quality > High?
Playback Frame Rate > Full?Motion Tab > Distort > Reset X button?

I run into this a lot as we use uncompressed 10bit quite often and end up with little green artifacts and other miscellaneous stuff just there. Applying a matte choker works for us and adding a couple of pixels of blur helps clean up the edges.

Yep, those little green things really bug me.

Perhaps the green bits are a 10 bit anomoly. I use 8bit almost exclusively and have never seen them.

It is a weirdness only found when using 10-bit.

On Sequence Settings…
Video Processing Tab…
Motion Filtering Quality set it to: FASTEST (linear)That should take care of it…

I capture in 10bit, have a 10bit sequence, but render in 8bit YUV.
Why?
Because this problem has been around ever since FCP ‘supported’ 10bit.
The fact that it’s STILL a problem is frankly an embarrasment.
I never render in 10bit within 10bit sequences because of this.The workarounds?
Render in 8bit – sure, that works, but you don’t get quality 10bit grading/FX.
Set your Motion Filtering quality to it’s worst setting (linear) – sure, that works, but if you have any digital moves, re-framing going on, looks like puss.
I’m not flaming here – just really disappointed with the lack of commitment by Apple to solving this.
I have reported the problem to them, as should you all, but it’s been what, 4 years now?
