How can we improve After Effects?

← After Effects

Latest version of After Effects won’t read DNX HD Quicktimes? Not sure if I’m affected by the QuickTime Drop in the latest version.

Latest version of After Effects won’t read DNX HD Quicktimes? Not sure if I’m affected by the QuickTime Drop in the latest version. The QT file is good since I can open it in QT player. After Effects shows a gray frame and the audio, no error messages. Tested it on 6 machines we have in here, all of them QT with DNXHD is broken, I have countless projects that do not work anymore, Had to roll back to version 15. Please fix

Thank you for filing this bug. Can you provide us with a link to a file that will not import into After Effects 15.1? Send it to aebugs@adobe.com if you don’t want to post publicly.

After Effects 15.1 does support DNxHD and DNxHR codec QuickTime files. The problem you are experiencing is likely either a limitation of this support, or a damaged file.

Since the release of After Effects 15.1, we have seen reports of similar cases where QuickTime files using natively supported codecs will not import. When files are available to us we can inspect them; mostly what we are finding is that the QuickTime file in question is structured in a way that is no longer supported. As the QuickTime format was developed over many years, it incorporated a number of unique features that are not supported natively by After Effects. (For example: complex edit lists, where the single QuickTime file could contain multiple media streams with in and out durations that were defined by an edit list, much like an NLE could create.) In previous versions of After Effects, the 32-bit QuickTime process was available to handle these cases. Now that this is no longer available, such files will not import. For a future update, we are looking into providing better error messages for cases like this.

We would like to look at your file so we can validate the problem and identify if there is an improvement we can make in our support for QuickTime files. That said, we do not intend to try to replicate support for all features that were in QuickTime. You may need to transcode the video into a new QuickTime file, using an older version of After Effects, Adobe Media Encoder, or another application.

    Thanks, we'll have a look at the file. It would also help us to know what application created the file.

    You can install older versions of Creative Cloud applications; instructions are here:
    https://helpx.adobe.com/download-install/using/install-previous-version.html

    When you install a new version of a Creative Cloud application, there are two scenarios:
    - Yearly upgrades install into new folders, and are usually differentiated by whole version-number changes. (Ex., 14.0 vs. 15.0, or CC 2015 vs. CC 2017). Note than when installing a yearly upgrade, there is a hidden option you need to disable to prevent the installer from removing the previous version.
    - Updates and patches install over the previous release of the same version, and are usually differentiated by decimal version numbers. (Ex., 15.1.1 vs. 15.1 vs. 15.0) You can not have more than one of these versions installed at the same time.

    By using an old version of After Effects or Adobe Media Encoder to transcode the video, I meant that you could install a previous year's version (ex., After Effects 14.2 or Adobe Media Encoder 11.2), as offered through the Creative Cloud desktop application. Or, if you wish, revert your installation of After Effects or Adobe Media Encoder to the version last capable of using 32-bit QuickTime processes (15.0.1 or 12.0.1, respectively), before reinstalling the latest updates.

    I hope that helps clarify what's possible.

    sent a link to download the video. Having to transcode all and each one of our projects is not a viable solution, we just cant do that. Also you mention using and old version to transcode, how one keep and old version at hand? When CC install a new version, the old version gets removed. I know that the files are not damaged since they were in use last week before the update, and also because they play fine with the QT player.

    Lets hope this is something that can be fixed, otherwise we are stuck on this old version since we can't transcode the 50 something active projects we have at the moment.

    Thanks and let me know if you think this can be fixed.
