Movie-Reading on Mac OS X
In macOS, there is only a single movie-file reading subsystem, designed mostly for reading h.264 and h.265 data. You may need to install the Apple Pro Video Formats package into macOS to read formats such as ProRes™, if it isn’t already installed.
ProRes images all black? macOS Ventura broke 16-bit ProRes encoding on M1 Minis (only), which worked fine on Monterrey. Pending any fix from Apple, we’ve added a “Force 8-bit ProRes” preference, which allows ProRes to be decoded to 8-bit, the most common case. When this preference is on, all ProRes decodes will produce 8-bit data, even if 16-bit or float formats are requested. Feel free to lobby Apple for a fix. (Don’t turn this preference on unless you actually have this problem.)
SynthEyes has some residual code for reading and writing Quicktimes in older versions of macOS, which may or may not be usable depending on your setup.
