    About incompatible media in Final Cut Pro X
    To prepare for future versions of macOS, detect and convert incompatible media in your Final Cut Pro X and Motion projects.

    [snip]
    In macOS versions up to and including macOS Mojave, third-party software has extended the QuickTime 7 framework to support many incompatible media formats. In versions of macOS after macOS Mojave, the QuickTime 7 framework will no longer be available, so incompatible formats won't be supported in Final Cut Pro, Motion and Compressor.

    Third-party developers may continue to offer compatibility with some formats by building support directly into their apps. Contact developers of third-party apps for more information about media formats supported in their apps.

    Here are examples of media formats affected by this transition:
    AV1 / VP9
    =====

    There are a bunch of other formats listed. And the article was posted at the end of April, 2019.

    Has the AV1 group addressed this issue or announced plans to?

      Jim- AV1 is really still a work in progress. On YouTube it's available for SD video to play with (if you opt in): HD and 4K (where it's really needed) is a way off, though development progress is rapid.

      Apple devices support H.265 in hardware. It's not clear if this is built into a fixed function VLSI hardware component, or if it's more programable (e.g. DCT and vector processors can be combined into new algorithms). If it's the latter, then it might be possible to add AV1 support as a firmware update. If not, then perhaps the GPU, AI/ML (math engines), and CPU can be used to decode AV1 at the cost of more battery usage. Otherwise AV1 won't be available until Apple adds hardware support.

      As for MacOS support: previously VP9 (and early VP1?) was supported through QuickTime 7. Moving forward Apple is dropping QuickTime, though since they joined AV1 I'd expect them to add AV1 to AVFoundation (Apple's newer media support system) which would bring support to all Apple apps. Note the AV1 spec appears to have been finalized around Jan 2019 (perhaps sooner; still being updated in Jan): https://aomediacodec.github.io/av1-spec/av1-spec.pdf . Since literally everyone is on board with AV1, expect to see full Apple support in the future, on both desktop and mobile.

      Again, the tech in AV1 could be used to produce high quality DI variants, e.g. ALL-I (intraframe- no interpolation between frames), similar to ProRes except much smaller file sizes with equivalent quality. The same can be said for photos and stills: HEIF is basically H.265 for stills (latest iOS devices can store images in this format). Think of the JPG frames in MJPEG being H.265 stills (ProRes is basically a variant of MJPEG). The same can be done with the more efficient AV1 for DI video and stills.

        With the current version of Mac OS and Final Cut Pro X you get a "missing plug-in" message when you try to access Cineform files, with no explanation or link to where you can solve this problem.
