The only thing keeping me from dropping premiere pro is how easy it is to create broadcast close captioning (608 and 708) within the program. I see no way to do popup or popon 608 and 708 broadcast captions within Vegas Pro. Need an update so I can drop Premiere Pro. I haven't found a way to do it as easily within Vegas. If I missed it let me know.
I used to caption my TV show in VEGAS, forgot the exact method, but I'd put in my titles, then when exporting it also generated a .srt file that I was able to give to the engineer at the TV station, and they were able to import and encode the captions that way.
