Thanks for the comment, Dr. M, I was waiting for your intervention! You are the expert here, and I'm glad you punctualize the fact that the original work has been changed not once, but twice, on BD... well, the idea to use the BD and color grading using the laserdisc as color reference was, well... just an idea!
I think I should stick with the original mission: to use the laserdisc as video source. But please, download the test clip and tell me what do you think about it; as the processing is really slow, I must receive some feedbacks before I start the processing - I could not let my poor PC work for a week, discovering at the end that the result is not good enough... (^^,)
