    The Twitch presets that we include with Wirecast 5 were vetted by Twitch staff. They will provide you with an "Excellent" quality signal as reported by the Twitch dashboard. It seems that many users of Wirecast 5 have overlooked this. I have seen several people reporting incorrectly that Wirecast doesn't support Strict CBR.

    If you want to make custom presets that provide Excellent quality with Twitch, they recommend that you set –vbv-bufsize to a value equal to 0.8 * video bitrate. You also need to enable –nal-hrd cbr.

    So good to see someone else experienced that blackout problem after Mavericks came out. I was also using my old 4.0 settings and didn't notice there was an option for CBR now. Thanks so much for the tip! Can't wait to test it out this week.
