Thanks for the suggestion, I have tried both, with ProRes I rendered the whole timeline, while with DVC Pro 50 2min where my titeles can be found, no significant improvement in either case. As well given the fact that my footage is not super high in quality, for a test I chose a random visual from some demo. Placed my graphics on the footage no significant improvement. As I mentioned the quality is fine in the timeline and as a QT Export, so for potential broadcast I do not see a major problem. But for DVD production, it is not acceptable, not sharp crisp or solid colors. Thanks.
