Is the issue that the lights are off
The video you quote is running on the startrekphase2DE YouTube channel
When I look at this video, the video looks fine. There are some scenes where the set lighting leaves some people in shadow, e.g. at 1:00
where Spock, McCoy and Kirk are all in shadow, yet the exposure for the three guests are all correct.
This is even more apparent at 1:11
where the back of Kirk's neck is correctly exposed, yet the rest of his face is in shadow. Gil Gerrold, on the other hand, is perfectly exposed meaning that the darkness is a lighting problem on the set, not a YouTube problem darkening the video.
It is very possible that this lighting setup was designed for dramatic effect and to emphasise the importance of the guests.
Please look at the following clip: http://www.youtube.com/watch?v=EPhVJzFnTRU
This video clip allows you to compare between the original video as we received it on the left, and the enhanced version on the right.
The video on the right was corrected using the video processing software vReveal Premium, version 184.108.40.20629M, where the software's automatic correction features for Auto Contrast, Deinterlace and Auto White Balance were used. This does improve the contrast quite a bit.
Please tell me which version works best for you by adding a comment. Do you prefer the version on the left or the enhanced version on the right?
If you guys prefer the version on the right, and there is no objection from James's video team, I could release the video in the enhanced version on YouTube.
I have now also uploaded two different enhancements as full videos for you guys to comment on. Which do you prefer:
1. Untouched original version: http://www.youtube.com/watch?v=tImlBjkZBi8
2. Contrast enhanced version: http://www.youtube.com/watch?v=9v0BsaIgpGw
3. Contrast and white balance enhanced: http://www.youtube.com/watch?v=UBC_4Jww6IU
Please give me your comments so I can better understand which version looks best for you guys.
