I have 2 problems while rendering out of Final Cut X.
Artefacts & Controlling the H264 bitrate:
What I'm rendering has a moving/shaping color background, which gets rendered with wave like artefacts, which can be seen especially in the lower center part if the screen, here is the example (you'll have to watch in on the youtube page to see the artefacts):
It doesn't matter if I use H264, ProRes HQ or even if I export uncompressed, always get the artefacts...
This backround image is an included with Final Cut X Apple Generator, so it should be flawless...
Could this be a bug or poor implementation from Apple?
How can I control the H264 bitrate, there is a setting that you can set for a max bitrate, but you can't set a minimum or a constant bitrate
So my questions are:
1. How do I render without artefacts?
2. How do I control the bitrate?
3. Does the bitrate matters for digital projection in a cinema, as long as the image looks fine on your computer screen?
