Adobe Media Encoder. Adobe Prelude. Adobe Premiere Elements. If you run a Windows operating system on your computer, all recent versions now support some form of Operating System (OS) level decode for Dolby audio.There are a few exceptions, though:.
Windows 10N/10KN: Windows 10N/10KN version does not include the media package required to decode AC-3. You can find instructions on how to fix this issue in the following article on the Microsoft support site:. Windows 8.1N/8.1KN: Windows 8.1N/8.1KN version does not include the media package required to decode AC-3.
You can find instructions on how to fix this issue in the following article on the Microsoft support site:. Windows 10 LTSC build 1803: This build of Windows does not include the Dolby codec. You need to upgrade the LTSC build to the full Windows license.Older versions of Windows:. Windows 7: Windows 7 does not include the media package required to decode AC-3.
The best solution is to upgrade to Windows 8 or Windows 10. It is never our goal to remove capabilities from our products.
Unfortunately in this case, we had no option but to change the way we accessed Dolby functionality and for some users this caused a disruption in workflow. Ultimately – we’re sorry that you’ve experienced any difficulty, below are some suggestions to both address the current situation and best practices for moving forward.
Move to the latest OS and application version.For Windows, consider an update to CC 2018.For Mac users,.This is our strongest suggestion. All windows versions above Windows 8.1 and Mac OS 10.11 or above contain native support for Dolby decoding functions. If you need to migrate work in progress, use a third-party utility like (a free open-source video transcoder) to convert your MTS/ACS files. Rename the files and reimport them into Premiere Pro. Then,. Recover your CC2017 versions that included Dolby.If you can't move to the lastest OS and CC2018 application version, recovering your CC2017 application including Dolby functionality is another potential path.On Windows, try to use to roll back the state of applications on your computer to before that time.On a Mac, you'd use Apple's.These back up versions will restore your machine to it’s previous state.
To prevent that changing, when upgrading Creative Cloud apps, use to retain older versions rather than the default behavior, which is removing them. Use a system backup or image from when you had CC 2017 installed.You could possibly use either backup to get back to where you were before. At a minimum, you'll need both the Premiere Pro and Adobe Media Encoder apps.Going forward, when upgrading Creative Cloud apps, use to retain older versions rather than the default behavior, which is removing them.
