I am a film editor that does basic DVD authoring for clients (not distribution) using DVD Studio Pro. On a recent project my DVDs are substantially brighter than the master file I am using to encode. Does DVD Pro do some sort of IRE shift up in its encoding? If so, what are my options for creating a DVD that accurately reflects the image values of the original.
DVDSP doesn't do anything to the IRE level, but its internal encoder is expecting the media to be in a certain form.
What you are probably seeing is a levels/gamma shift resulting from media with a different colourspace than Apple's codecs.
DVDSP is expecting media to be 1.8 gamma with levels in the 0-255 range (critically with black at 0). Some NLE's work with Media at 2.2 in the 16-235 range. Encoding this through DVDSP leaves you with overbright low contrast video with blacks distinctly grey.
The options are to encode separately in Compressor with setting adjusted to add contrast and gamma shift, or to use another encoder like Bitvice, which has a "studio RGB" button for this.

Can you suggest how to compensate the offset in compressor. I tried various settings but without luck.
Should I just give it up and purchase bitvice?
