On machines with QuickSync support (i3/i5/i7/i9 and some Xeon CPU's), VT routines will use that. It's kind of a black box, in that they don't specifically say which hardware is (or isn't) supported. I've noticed pixelation at the beginning of every keyframe interval (usually 2 or 4 seconds) if the peak buffer setting (don't remember exactly what it's called in OBS) isn't set high enough.įrom Apple's Documentation for VideoToolbox: Use a Mac compatible graphics card with your primary boot display and use the NEW graphics card with your high. You can use two graphics cards in your Mac Pro. These work out of the box vanilla however you get no boot screen. To get the best quality (with QuickSync, at least), you have to set your buffer to be around 2x the bitrate of your stream. The Non-mac AMD card are suppose to be more reliable however you get no boot screen. while taking 20-megapixel photos or 4K resolution video. On my iMac Pro, VideoToolbox is either using the Radeon Vega 64 or the T2 (it has been suggested that the T2 handles some video work), or a combination of both I know for sure the Radeon GPU utilization goes up during ffmpeg h264_videotoolbox encodes, and that it maxes out at the same level as QuickSync (12-15 1-2Mbps HD + SD streams simultaneously was the test).Īs for anyone else looking to answer the same questions as the OP, any MacBook Pro, 2015 or later, with an Intel Core (i3-i9) CPU will be fine at live transcoding and recording. Today, only the low-end Mac mini and MacBook Pro models offer spinning 5400 RPM drives (7200.
