( Randal Schwartz, who had recommended ScreenFlow, described my recent work as “a well produced video” and was surprised when I told him it had been done with ScreenFlow!)Ī couple days ago my MacBook Pro offered to install the latest OS X update that promised better security and stability. I have been using ScreenFlow for a couple weeks, and have been generally quite pleased with it. The problem does not occur when the colors is set to Millions.Īccording to Apple, the latest update to Leopard (10.5.5) “ncludes extensive graphics enhancements.” Unfortunately, these “enhancements” do not play well with ScreenFlow. UPDATE : Further investigation suggests that the problem occurs when the display colors is set to Thousands. If you switch to thousands of colors the title bar for other applications gets stripes in the title bar–even without ScreenFlow running. UPDATE : Working with the good folk at ScreenFlow, it does seem that the problem is pretty clearly with the Mac OS. The software has been buggy and crashtastic – the one thing I can’t have when clients are paying me for webcasts.įor now, I still end up with two cameras – my Logitech C615 for GoToWebinar, and the Canon/Blackmagic combo for everything else.UPDATE : Mac OS 10.5.6 is out and says that it “Includes fixes for possible graphics distortion issues with certain ATI graphics cards.” It does appear that thousands of colors now displays properly. I’ve also tried a few other software products that purport to do the same thing, like Camtwist and Manycam, but I’ve had really bad stability results. Unfortunately, during my testing, it constantly used 100% CPU of one core, and I don’t like having my laptop fan going while I webcast. It’ll even let you add additional effects live, like removing backgrounds or overlaying text. It takes takes the Blackmagic UltraStudio’s input and acts like a USB webcam for most software. If you want to spend even more money (around $500), and you’re willing to put up with high CPU usage, check out Telestream Wirecast.
