Comp issue

So I've created a credit page in text editor.  I was getting some aliasing so, as some here suggested, I used the text (on a gap) as a matte with a white color for a fill.  I then add an Action to adjust my filtering and when I make a matte key as described, the text seems to change premultiplication and get ratty looking.  Adding an Action takes care of this.  As you can see by the attached composite image, the matte is being effected by the brightness of the background.  I'm using a Blend mode.  In the other attached image, I've inverted the matte and you can see what is going on.  How can I prevent this from happening so the text is the matte without being effected by the background.  I've tried every blending mode but nothing helps.

I'm not sure I totally understand your effects setup (is this in CFX or all in the timeline?)

 

That said, I guess I'm also not sure why you have a hard time getting clean text straight out of Text, although I am saying that as someone not on Smoke Mac, so I don't know if the font renderer and/or the AA options in Text are fundamentally different from Flame and comes up with different results.  Not knowing your exact font, this is directly from Flame text sans drop shadow:

Bob, This is not in a CFX.  Created a text on a gap on the timeline.  Copied up to thumbnail.  Edited a white color onto timeline.  Added matte, selected text.  (This font was very aliased on diagonal edges).  When  do this, I get premultiplication noise.  I add an Action to clean this up and to add filtering to the text.  When I add the Action, I get this matte issue blending with the background.  

 

I've found other fonts having various aliasing issues but I"ve had so many problems with Smoke on Mavericks that it's hard to tell what's what.  At least now with EXT 1, if I enter the text editor, I can see the video underneath.  This was not the case with SP1, in fact, if I edit a text created before EXT 1 I don't see the background still.  Only when I create a new text does this work.  

 

Either way, it appears to be some blending option that I may have wrong somewhere?  I'm not sure why the matte is being effected like this.

I'm still not following what you're doing ('Copied up to thumbnail' ??) so let me try and interpret and see if I got it right or not.

 

  • You create a Text effect on a Gap clip and pound out some text.
  • You're then dragging the Text effect to the library
  • You put a white clip on the timeline, put it in a Container, and then click 'Add Matte' and select the text effect from the library.
  • At this point you get a premultiplication error?  Black outline around the text?
  • Then you add an Action to "clean this up" -- how?

Prior to Action, it sounds to me like you probably just have the wrong premultiply settings on the Comp effect.

By Thumbnail, I just meant copy up to the area above the timeline when in Thumbnail view (I forget the AD name for that area).  I add a white clip to the timeline.  Then I just select the white clip and click on ADD MATTE.  I add the matte.  Not quite just a black outline but a raggety image.  Looks like just a fill for a matte. Toggling the Comp premultiply setting to unpremultiply makes no difference. I just add an Action to this matte container and that cleans up the text as soon as I add it.  Then I just change the filtering in Action to smooth any aliasing.  That's it.

I accidentally captured this at the wrong resolution, but all the important bits can still be seen.  See if any of this behaviour looks familiar.  If you're not getting the same results then I'm not sure, perhaps there's a Smoke-specific difference happening that someone else will have to help you with.

Thanks for testing.  Same steps.  The premultiplication toggle was not changing anything for me.  Only adding Action and that is where the Matte is blending with the background.

With just using the Text Editor, deselect Auto-Softening and increase the anti aliasing.  Set-up/Rendering/AA (I usually use 9).

In Action, I've found it better to turn off the Hardware AA and use the software AA for rendering text.

I've done that.  I'm still not sure what the blending mode issue is. I've kind of given up on trying until all the Mavericks issues can be squared away, if that's possible.  Lots of weirdess so very hard to figure some of these things out.
