[Jack Shepard] “If that is possible, what would the setup be for that?”
It is somewhat close to possible, but it is not the way you should work.
What you can do (and what we usually do) is let the Media 100 stripe the tape. Therefore we set up our timelines to the start TC we want to use for our program (10:00:00:00). Now go to Master to Tape, turn on Leader, set the mode to “Record” and “Beginning of Tape”. Set the deck to “Internal” and “Preset” for TC generation, and master the leader.
Shortly before the actual program starts, cancel the master and set your deck back to “Regen”. Then switch to Assemble, “Timecode” and use maybe 5 seconds of leader. The reason for this is that Crash Record (mastering to Tape via “Record”) is not frame accurate. It usually is close, but of course if you want to do an insert or assemble edit later you would not be able to easily do that.
Therefore it makes sense to master the Leader first, and then stop and use the Assemble edit to master your actual program.
