Thank you again Paul for your answer.

You're right, to use "Frame" in TimeCode has no sense. About millisecond I don't know if it is necessary, maybe it isn't, only practical test can say. Anyway some subtitle file format uses it.

Regarding font: the FontChange should be considered for all the text and not only for the TimeCode. You're right, an event could have a lot of speakers, for the moment I think could be set 10 different shorthand, for example "crc1"=FontType1, "crc2"=FontType2, etc. The stenomachine has the ability to write numbers from 0 to 9. The combination of FootPedal+Number could be set has trigger.

But as I said I'm still in planning phase, and the possibility to test the entier process will make things well defined.

Anyway thank you for your consideration.

Daniele.
