Apple warns of video codecs incompatible with the next generation of macOS

iMac Pro e MacBook Pro

A few days ago, we reported that Apple updated its main video editing applications, including iMovie and Final Cut Pro, as part of the process of transitioning apps from 32 to 64 bits on macOS.

Although this key will only be completely turned over in a few months – with the launch of Mojave’s successor, possibly macOS 10.15 – Apple is trying to make everything clear and has published a support page, in which it explains the transition process to 64 bits and which are codecs video will no longer be supported.

As we said, Apple’s video software can now detect which types of files will not be supported; however, after the most recent update, they also automatically convert them to a compatible format. More precisely, media files created from formats or codecs QuickTime 7 will be incompatible with the next generations of macOS.

To ensure that you don’t experience potential problems with playing and / or editing videos after macOS Mojave, Apple has highlighted the importance of checking and converting all incompatible media files now. The company also stressed that, after the update, the option to convert incompatible files will no longer be available.

Below are some examples of media formats affected by the transition (which includes the late Perian); see here the complete list of file types incompatible (and compatible) with macOS after Mojave.

  • 3ivx MPEG-4;
  • AV1 / VP9;
  • CineForm;
  • Cinepak;
  • Collection of codecs Perian (such as Microsoft MPEG-4, DivX, 3ivx, VP6 and VP3).
  • DivX;
  • Flash Video;
  • FlashPix;
  • FLC;
  • H.261;
  • JPEG 2000;
  • Microsoft Video 1;
  • Motion JPEG A;
  • Motion JPEG B.
  • On2 VP3, VP5, VP6, VP6-E, VP6-S, VP7, VP8, VP9;
  • Pixlet;
  • RealVideo;
  • SGI;
  • Windows Media Video 7, 8, 9.

The formats and codecs described by Apple will therefore be incompatible with the next major macOS update. If you intend to update your Mac, it is essential to convert these files to compatible formats now.

To do so, you can use Final Cut Pro, Compressor and QuickTime Player (version 10.0 or later) – the method for converting files from QuickTime, however, will not be supported by the successors of macOS Mojave. Another good, free converter alternative is HandBrake.

As for Final Cut Pro, Apple describes on this support page which cameras are supported by the editor (therefore, with future generations of macOS as well). The company is expected to announce the next version of macOS during the Worldwide Developers Conference (WWDC) 2019 in June, with its launch scheduled for the second half of this year.
