For David Roth Weiss
David, this is just to pick up on your recent criticism of myself in an earlier thread.
https://forums.creativecow.net/cgi-bin/new_read_thread.cgi?forumid=8&postid=940334&univpostid=940334
Since you seem intent on minimizing my concerns about a valid issue, calling it unwarranted “criticism” and using a lazy search as your source, I thought I’d provide some better results from my own search.
This issue has been around a long while and just because you never heard of it doesn’t mean you need to make it sound like I’m some forum sh!t disturber, thanks.
For instance, you won’t find me in the following threads (try searching washed out color next time):

Is that enough yet? So much for my unwarranted criticism. And for the record, I love Compressor. I get beautiful results b/c I know the limitations. And, if you’re actually interested in the issue (not just attacking my credibility) the issue IMO has to do with adding setup. Try watching your material on an NTSC/PAL monitor. I’m guessing you’re basing all your confidence on DVD’s as they appear on your Mac monitor.
Thanks,
James

Here’s the original link I’m referring to:

I think I got confused with all the tabs I had open in my search. Here’s the text:
(reel2reel Quote) Compressor most definitely shifts the Gamma (which makes the colours look washed out) when encoding MPEG-2. This has been mentioned many times in the DVDSP forum. (end reel2reel Quote)
James,
I did a search, and it seems you’re the one who mentioned the gamma shift on the DVDSP Forum. And, in the thread I read your assertion was disputed by another forum member who suspects issues in your workflow. I also believe there is most likely some other issue involved, and that your criticism of Compressor is unwarranted.
For the record, I have many different tools to choose from for encoding MPEG-2 on both MAC and PC, and if Compressor were causing gamma shifts I’d be using something else. However, I’ve encoded literally hundreds of DVDs with Compressor 2 over that last two years without the gamma shift you mention.

James,
Like most human beings I am fallible, i.e. capable of making errors. If I have made one in your case then I sincerely apologize.

Hey James.
Within Compressor, there is a gamma correction filter within the ‘filters’ button.
You can play with it until you find something that you like (values .01 to 4.0 and default is 1.0)

Holy, I never knew that! Thanks a lot.

David, thanks for the apology (I hope your sincerity is sincere!).
It was the tone of your post that got me. I love my Final Cut Suite and I love trying to help people, so I take these things seriously.
Cheers,
James

Oh, I spoke too soon. Duh.
Yes, this is what I’ve been using to compensate, along with some added contrast. I’ve gotten great results. I’m not sure what I thought you meant.
I wonder why only some people have a problem with this shift and others don’t??? I find you can’t really tell unless you play it out through a regular DVD player to an NTSC display. My only guess is setup is being added twice. But that’s just a guess.
Thanks again.

James,
You’ve answered your own question at least once in this thread, a gamma shift has to be a setup issue. Where exactly it’s happening for you I don’t know, but I have never had that problem with Compressor.

I just ran some ntsc bars through compressor and it eliminated the super black bar in the pluge.
that can’t be right.

Chris, I wasn’t asking a question. I was just answering an older (buried) thread where David discounted my claim, which has actually been well-discussed on this site. I was merely trying to add some useful information for anyone who might be interested, so this thread wouldn’t be a total write-off.
