If all your decks have SDI, capture through a card like Kona or Decklink. Keep it all at the same rez. & you won’t have a problem. Yes, you will waste disk space but it all comes down to dollars. A fully loaded FCP is $20-30K less than Adrenaline. With the left over $ you could buy a $1000 SDI Cobalt Digital converter for your Beta, enough extra hard drive space & get another DV deck with SDI & still have some left over. Adrenaline is buggy, over priced & for the money, lacks features. Xpress Pro with mojo is way to slow for anything other than DV25.
