It’s one thing putting up with Avid because of their kludgy made-it-up-as-they-went interface. I’ll grant that video editors are not particularly technical people, so the cost of modernizing the UI wouldn’t be worth the retraining costs.
But if we pay 90,000$ for the best Avid editing station, which includes 4,000$ for a quad-core Xeon workstation, it should bloody well use more than one processor at once when rendering effects:
If your code is so old and krufty that you can’t support multiple processors for something as simple as effects or video encoding, it’s time for a rewrite.
