For TC. Hit TC/CHR (I think, I’m not at the machine) F1 until you hit internal F2 to preset.
For Video. Hit Video in, change to INT signal, change INT signal to Black Burst (F2 menu)
Now if you go to your home screen you can manually punch in TC (so you can just hit 00:58:00:00 (or whatever you want to start at) hit ENTER afterward.
Rewind and REC/PLAY
Should work fine.
Or if you are using FCP you can set the machine to INT / AUTO and FCP will stripe for you without you having to change the machine around.
As for insert editing, your best bet is to read the manual…
