Contrary to previous information about 3rd party video codec support changing with the release of macOS Catalina, and the end of 3rd party codec support natively in the macOS, according to an Avid Press Release announced at IBC 2019 last weekend, Avid appear to be suggesting that there will be macOS support for Avid DNxHR and DNxHD codecs. This update adds the following video codecs for use by QuickTime-based applications: Apple Intermediate Codec Apple ProRes AVC-Intra DVCPRO HD HDV XDCAM HD / EX / HD422 MPEG IMX Uncompressed 4:2:2. QuickTime does not also support the codec (i.e., DivX) used in compression done on the Windows operating systems (or other systems apart from Mac). Solution: Try to install Perian (a QuickTime component) or other add-ons/plug-ins. Make sure that your QuickTime player is up-to-date (from QuickTime X to QuickTime 7) and is compatible with add-on/plug-in. I have the same issue with all my mp4 videos containing AC3 audio. It worked perfectly well before the last update of High Sierra. I've read the kind answer provided by Jon Walker below, but it seems quite an heavy and consuming task to convert all my videos for a codec issue. I hope there must be a way to make Quicktime recognize AC3 audio codec. When a video is not played you could go around in search of special codecs with something like Perian to install to QuickTime or you can go the easier way and perform a QuickTime alternative download of a free video player for Mac OS X.
Why Do We Need MP4 Codec?
Not all video formats can play on Mac devices. You may find that the media player on your Mac gives an error whenever you play an MP4 file. To solve this, you need a codec. An MP4 codec enables the media players such as QuickTime to play files that it did not support such as MP4 files. Although QuickTime on Mac devices supports MP4 files, it only contains some of the codecs, which means that if your file has a codec that is not supported, it will not play. Therefore, you should install the required codec or convert the files to a format support by the media player.

We’re all familiar with the concept of codecs. And we’ve probably all run into a problem or two with a codec in the past – a file that works on one computer doesn’t work on another, or works in one app but not another. In fact, codec issues are one of the main reasons we built EditReady.
This post will cover the basics of where codecs live on the Mac, and how you can go about resolving basic codec issues.
Traditionally, all the codecs on a Mac were stored in one folder,
/Library/QuickTime. If you’ve got an older Mac OS X install and look in that folder, you’ll probably find all sorts of detritus from codecs of the past – DiVX.component, Perian.component, etc. These components are part of the old “QuickTime 7” framework. If you’re working in Final Cut Pro 7 or another older app, these are the only codecs that matter. This is also the only type of codec that can be developed by third parties.
Starting with Mac OS X 10.6 (“Snow Leopard”) Apple introduced a new set of media technologies – AVFoundation, CoreMediaIO, and others. These modern media frameworks don’t use the older components, and instead introduced a separate set of video codecs. You’ll find these in
/System/Library/Video (And often in subfolders from there).
Apple hasn’t opened this technology up to third parties, so only Apple can create these types of codecs. Macs come with some codecs preinstalled (like Apple ProRes) but others are only available as part of the Apple “Pro” apps like Final Cut Pro X. The most important of these, in terms of working with video on a Mac, is probably the AVC Intra codec, since AVC Intra is used by many modern cameras (like many XAVC cameras).

We’ve seen a number of issues related to these modern codecs. First off, some users simply end up with corrupt or missing copies. This can be due to a bad update, or an overly aggressive “cleaner” application on your Mac. If you previously had the codecs and suddenly they’re gone, you can reinstall from the Apple Pro Video Formats download.

As we prepare for the impending release of Mac OS X 10.11 (“El Capitan”), many users will choose to do a full reinstall instead of just updating. This can lead to confusion because codecs will be missing after the update.
If you don’t have the codecs at all, an easy way to get them is by installed the Final Cut Pro X trial. Alternatively, you can find instructions online for installing them manually.
