Hello, I've been noticing that when I'm trying to do video playback in Premiere Pro CC (2017) the playback is choppy and slow. This seems strange given I'm using a high-end Mac that has been spec'd out for video editing.
Mac Pro (late 2013) Trash-Can-Style
OSX Yosemite (this cannot be upgraded due to the version of Avid we are currently using)
Processor: 2.7 GHz- 12 Core Xeon
RAM: 64 GB
Graphics: AMD FirePro D700 6144 MB
Only Premiere Pro is open while I am doing the video playback, the files are Apple ProRes 422 1080x1920 50i, running from a USB 3.0 drive (connected to a USB 3.0 port). Neither the internal storage or the hard drive storage are any where close to be full.
Multicam? Could just be a slow drive. If you are running two or more streams, that's marginal for USB3, especially 50i. How does Avid perform with these same files linked via AMA? Are there any background processes going on, like Premiere's audio "conforming" functions? Have you tried a test using either the internal flash storage or an external Thunderbolt 2 drive?
