Flashes at Dolby DSS200/Kinoton DCP 30 SX II

Post by thomas_b »

I have the problem that the DCP's I create with DCP-o-matic starts with flashes/interferences - so it is in the transition from the film before to the film I created with DCP-o-matic. Then the film/DCP is looking good.

The problems are only by the system
­> Dolby DSS200/Kinoton DCP 30 SX II.

At the system
> Sony XCT-S10/SRX R515
there are no problems.

I create the films with 25 fps and 1998 x 1080.

What can I do to look them better?

A flash / disturbance exactly on the transition between DCPs is sometimes due to a switch in frame rate: some systems can't go, say, from 24fps to 25fps cleanly. If that's the cause I'm not aware of a nice fix other than something slightly ridiculous like:
  • 24fps DCP
    Few seconds of 24fps black
    Close dowser
    Few seconds of 25fps black
    Open dowser
    25fps DCP
Perhaps you could test with two adjacent DCPs at the same rate?

yes... this was the problem:
I made my DCPs now in 24 fps and I have no flashes anymore.
I think the other DCPs are also 24 fps

Very stupid of Dolby/Kinoton!
Sony is in this case much better.

Thanks again!
