Apple<\/a>:<\/p>\n

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.<\/p>\n

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. 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.<\/p>\n<\/blockquote>\n\n

It’s a pity that Apple never brought the new QuickTime Player app up to the level of QuickTime 7.<\/p>\n\n

Among 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. 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.<\/p>\n

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. They aren’t included in Mojave’s System Information under its Legacy Software section, which only seems to cover apps and similar bundles. Most, perhaps all, of those listed in the Components section are provided in 32-bit form and will be unavailable in macOS 10.15, but there doesn’t appear to be any listing of formats which are<\/em> supported in QuickTime X.<\/p>\n<\/blockquote>\n\n

Most of the codecs which are becoming unsupported are those for video, but Apple’s list includes one still image format which could affect you, JPEG 2000. Although never popular, at some time in the past you may have saved photos or other images in this format, which is quite different from plain old JPEG (which won’t be affected by the loss of these codecs).<\/p>\n<\/blockquote>\n\n

I wonder what this means for Apple Icon Image<\/a> files, which can contain embedded JPEG 2000 images. Not to mention PDF files and NSBitmapImageFileTypeJPEG2000<\/code>.<\/p>\n\n
