Compression Problems
Hey gang…
I’m getting some compression problems that are awful. I have a scene that has three pieces of video on the screen at the same time – two on top and one all the way accross the bottom on my timeline. Well, I have noticed that when I view and render these clips that I get some serious pixelation to them. Yeah, I know that I am compressing them and one in a no-so conventional manner but how do I minimize this artifacting. I’ve tried changing the “Motion Filtering Quality” under the “Video Processing” tab in the Sequence Settings but nothing seems to make much difference. I’m pretty sure this has been tackled before but I need to find an answer or a proper workflow to make this work better. I’d rather not have to use Motion or After Effects for this.

Sounds like you might be on odd pixels:
Jump into the motion tab for each of your “windows.” Make sure they have a center value that is an EVEN number, no odd numbers and no decimals. eg. x = 245.3 y = 45.6 is NOT what you want!!! Make it x = 246 and y = 46.
Lots of people do this because they use the wireframe function and assume “set it and forget it” is good enough. Wirframe mode is great for testing moves or a quick reposition but I always check the center value on final render.
This method holds true for any image, video or graphic that is standing still in the frame. If you are moving the image around it will not matter but once it stops be sure to have the center value set as I describe above.
Bye bye blurry video.
If that doesn’t work try “Flicker Filter” or “De-interlace” in your effects palette.
Good Luck.

Yeah, I’m aware of that problem… But that’s not what I’m dealing with. Mine is a simple compression box of 50 percent scale and adjusted by even numbers to an area of the screen. De-interlacing doesn’t help and it’s not flickering. It just looks pixelated at times. Just take a piece of video and scale it to 50 percent, then render it. It looks pixelated.

I found my own answer and a SERIOUS BUG in FCP 5.0.2 If I go into the Distort tab and change my Lower Right from 243 to 240, everything looks perfect! All the other settings are -243 for Upper Left and Upper Right AND Lower Left is 243. Now that’s screwed up!
