Make a media player for small film festivals that on the chosen output (HDMI output) has the framerate of the played file.
A player with a playlist in which you can set the audiolevel of each file, set audio routing for each file, insert stills with a duration you can set while playing some music which you can set to a certain level.
It should play all possible files (like Premiere). With a Black Magic shuttle you can alter the framerate on the output of the blackmagic box. This means the Cinema beamer with HDMI in will switch (*****) to theinputted HDMI framrate. Thus finally the frameskipping of a Macbook pro or Imac is gone.
A Imac with a second screen (being the cinema beamer/projector) you have to set the refreshrate of the Imac, you can choose between 50hz or 60Hz. This is OK for 25 Frames per second (50Hz) or 30 Frames per second 60 Hz. Switching is manual and causes a black screen on the output while retiming. And all of the films of 24 Frames per second, 23,98 and 29, 97 have frames skipped since their timing does not fit onto 30 or 50 cycles.

It is about time that you come with a player for this purpose to accomodate small festivals that cannot afford DCP players, although it would be brilliant if your player would do DCP's as well.
But the playlist needs to be programmable, just like CueLab (Cuelab does not switch timing on the output either). Maybe Cuelab is a bit elaborate but a good example!

good luck let me know when it is ready so I can Test it :-)
