Apple warns of video codecs incompatible with next-generation macOS

A few days ago, we reported that Apple updated its major video editing applications, including iMovie and Final Cut Pro, as part of the 32-bit 64-bit application transition process on macOS.

Although this key will only be completely turned over in a few months with the release of Mojave's successor, possibly macOS 10.15, Ma is trying to make it clear and has published a support page explaining the 64-bit transition process. and which are codecs video will no longer be compatible.

As we said, Apple video software can already detect which file types will not be supported; however, after the latest 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 future generations of macOS.

To ensure that you do not face potential problems with video playback and / or editing after macOS Mojave, Apple has stressed the importance of checking and converting all incompatible media files right now. The company also stressed that after the upgrade, the option to convert incompatible files no longer available.

Here are some examples of media formats affected by the transition (including the late Perian); Here is 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;
  • Pixellet;
  • RealVideo;
  • SGI;
  • Windows Media Video 7, 8, 9.

The formats and codecs described by Apple will therefore be incompatible with the next major update of macOS. If you plan to upgrade your Mac, you must convert these files to compatible formats now.

You can use Final Cut Pro, Compressor, and QuickTime Player (version 10.0 or later) to convert files from QuickTime, however, it will not be supported by MacOS Mojave successors. Another good free converter alternative, HandBrake.

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