Thanks, sounds like 24fps is the way to go.  Have not been able to find out which server the festival it has been accepted for will use and the DCP may well be used for other unknown places. 

Sounds like creating 2 versions is not really needed.  Also looks like if I simply change the frame rate in DCP tab it will not change the name of the DCP so I guess I would have to tag the framerate on the end of the name.  Creating different version with different level audio was mentioned earlier.  If I do 24 and 25 will DCPOMatic need to do all its work again,  am wonerting if changing the version changes the name of DCP.

Thanks for everyones help,
Ben

Sounds not ideal, so it would be best to use premiere or something like that to do the frame rate conversion.

Optical flow or any other interpolation scheme will never give nice results for a 25 to 24 fps conversion. 25/24 slow down or 24/25 speed-up is an internationally accepted production standard even for high end productions.


Is playing stuff slowly supported by DCP standards?

What DCP-o-matic delivers will be a proper 24fps DCP and no-one watching it is able to tell that it was 25fps before. Delivering 25fps content to a cinema I would consider more of a problem.

Are you sure you will distribute this DCP to other cinemas with unknown capabilities? Then make it 24fps. Will you only play it on your local screen with known 25fps capability? Then leave it at 25 fps.

The best thing to do is to make two DCPs with either frame rate, copy both to the distribution drive and let the cinema decide.

Dolby DSS/DSP100 does not support 25/30 fps regardless of software version. Are there any more stubborn players out there?
