It doesn't make any difference whether you use footage from the EX1 & 3 cameras or the PMW-350K
BTW, I can confirm the audio bug involving footage shot with the PMW-350..
I get the same, using two ex3's on 3 systems. Is this supposed to happen? I thought it should be green too.
Keep in mind that the color coding above the time line has changed in CS5.
1. No color: no rendering required. A very easy codec, like DV AVI
2. Green line: material is rendered
3. Yellow line: Normally no rendering required, a moderately complex codec, plays back without any problems on normally fast systems.
4. Red line: May require rendering for smooth playback, a complex codec, can play back without problems on fast systems.
At the moment I only have .M4V material here and it shows with the yellow line. Don't worry about it.
