Perian update checker software#
They aren’t included in Mojave’s System Information under its Legacy Software section, which only seems to cover apps and similar bundles. Unfortunately, there’s no system-level means of checking which video, audio and still image formats remain reliant on 32-bit components such as codecs. It’s possible that some vendors may port codecs or other tools to 10.15 to support some of them in the future, although this looks unlikely at present. It’s a pity that Apple never brought the new QuickTime Player app up to the level of QuickTime 7.Īmong those which won’t be supported under macOS 10.15 are several Avid formats, Cinepak, DivX, Flash Video, FlashPix, GlueTools codecs, JPEG 2000, Motion JPEG A and B, Perian codecs (MPEG-4, DivX, and more), RealVideo, several Sorensons, and Windows Media Video (WMV) 7, 8, 9. However, because versions of macOS after macOS Mojave will no longer include the QuickTime 7 framework, you’ll first need to detect and convert incompatible media files to continue to use those files in iMovie. These incompatible media files were typically created using formats or codecs that rely on QuickTime 7-an older version of QuickTime that is included in macOS Mojave for compatibility purposes.
As part of the upcoming transition to 64-bit technology in macOS, you may see an alert in iMovie about media files that won’t be compatible with future versions of macOS, released after macOS Mojave.
