Unfortunately, quicktime never seems to recognize anamorphic movies as anamorphic. There was a different way to fix this in previous versions, but with QT 7.6 you need to go to window>show movie properties (cmd J) Then choose Video Track>Visual Settings. From there you can change the scaled size to correct for an anamorphic clip. For PAL, this means unchecking “Preserve Aspect Ratio” and changing 720 to 1024, so your dimensions are 1024×576.

In theory, you will achieve the best results by getting your graphics to move in full-pixel increments per frame, especially for vertical movement. This will require some maths 🙂
For example, if you text box is changing its y-position by 300 pixels then you will want this change to happen over 300 frames. So your keyframes will need to be 300 frames apart (i.e. 10 seconds at 30fps) If that’s too quick, multiply the pixels by a whole number (2 or 3 might work), giving you 600 or 900 frames, so that it slows down by half or a third.
I would also note that FCP-generated text also will look better on an interlaced external monitor than it will on your computer screen.
Hopefully this will make a difference -
We have been having a similar problem. Can you clarify “white sparkles?” We are getting random flashing white pixels. I.e. on a still frame there may be several pixels randomly flashing white. Seems to be frame specific and you can see them while the video is playing as well.
This happens over SDI and component output, through both Final Cut and AJA tv.We reported this to AJA who immediately sent a replacement Kona card. The replacement seems to have the same problem. We may try the driver rollback which has been suggested and will post the results.

Oooh, magic. Thank you.

Here is a 100% scale PNG (taken as a screen grab) of my original footage. I’ve managed to make the key work now, but only by duplicating the layer so that I have one with blurred edges and another with a shrink matte effect so that the interior is crisp.

Thanks for your input Jim. The footage was actually shot on Digibeta, so I don’t think it is a DV-related compression problem. Here is an enlarged screenshot of the original footage.

I would think that a nice clean line like that should key well, but I’m having to either turn noise reduction up very high (thus losing detail in the hair) or shrink and feather the matte (same problem with detail elsewhere) in order to get rid of that halo edge.
Your thoughts are appreciated.

Hi there, I’m new to posting on this forum, but have read posts here quite a bit.
Can anyone explain why the Primatte RT produces a halo around the edge of its matte? It seems like the footage has a nice clean separation between the green screen and the subject, but as you can see from the alpha matte, a new outline is created when the key is applied.

Additionally, the keyer seems to produce extra pixelation in the subject. The border between the subject’s chin and jacket clearly illustrates this.

This is 10-bit uncompressed source footage, by the way. Any help dealing with these issues would be greatly appreciated.
