Hi,
I am nearing the completion of a major project (actually, it is my first international project so hence my concern with what has (or has appeared to have) gone wrong).
Starting from the filming... I used a DVX100AE with everything in manual mode. The Scene File was on F6 with all the setting restored to default before using. The main thing which appears to have gone wrong is within the interviews (although there are traces of this throughout the entire doco now that I look). I set the iris so that the skin was about 75%, and there was not peaking of 100% by the zebra lines anywhere in the frame during the entire shoot.
I have been editing quite happely away for a couple of months but yesterday I exported out a Quicktime version of the doco (a couple of different formats from h264 to full quality). What I noticed was that during the main person's interview, her face went very red. After going back through the footage I looked at the video scopes (which I must admit I don't fully understand) and saw that in the RGB Parade, the Red went above 100% and even clipped. However, when I use the 'range check' on both luma and chroma, it says that the shot is ok. In terms of the shot, I did not alter colour balance or saturation at all, I only modified the brightness by turning it down and crushing some of the blacks.
So anyway, I'm at a loss as to what I did, and more so what to do now. I know a picture tells a thousand words so I have uploaded some image samples (including scopes) to http://www.topfloor.com.au/temp/image_examples.jpg . I have put two examples including how it looks in Final Cut and then how it looks when it has been exported into Quicktime. I never noticed it before now as even when I firewire it to my camera and onto a semi-broadcast tv, it looks really nice (as I presume it is able to show, or does something with the reds which are above 100%). However, when exported it crushes everything above 100%. Is that right?
The primary use of this video is for DVD so that is what I need to make sure it is able to play on correctly. Upon putting it to compressor, in the preview I notice it crushes the reds as well.
So, any help will be greatly greatly appreciated. I have a deadline looming of next week and this is a surprise to find so late in the project. Also, if anyone knows what I did do wrong (camera wise) and could let me know what I should do so I don't repeat the same thing in the future, it would be really appreciated as well.
Thanks again,
Matt
