Hi,

I was looking for a clear reference on how to use the diverse frame rates with midi timecode. I have a patch that sends the timecode through osc, can someone confirm if these numbers are correct?

24 fps - add 0 to the hour value
25 fps - add 32 to the hour value
30 fps DF - add 64 to the hour value
30 fps - add 96 to the hour value

Furthermore, can anyone confirm to me if with 30fps DF the dropped frame is calculated automatically by the timecode protocoll? Or should I do the math in my patch?

Thanks,

I think your numbers are correct, but I don't think the protocol does any calculations with DF.

Here is an original article with detailed information.
