You update the same way you installed ! Our installer will remove the previous version automatically.  Please go to our Download page

Please read our article : How to License AfterCodecs

You can find all of this info on the Overview of AfterCodecs page. Also, don't forget to regularly check for updates and read the Changelog of AfterCodecs !

Please contact us, don't forget to send the .log file generated by AfterCodecs and information about your setup ! Please also make sure that you are not using a forbidden resolutions and that you're not running the trial of AfterCodecs.

Please download and install the latest Visual C++ 2019 Redistributable. Here's a direct a to vc_redist.x64.exe : download, double click on it and pursue installation.

On Windows you should run your cmd.exe or Powershell in Administrator Mode, then run AfterCodecs installer executable with the /S argument, for example in Powershell : ./"AfterCodecs v1.9.7 Installer.exe" /S if you're in the extracted folder from the downloaded zip. Same goes for the uninstaller but you'll also need to specify the -Uninstall_AfterCodecs argument.
If you want to be sure that the installer / uninstaller exit automatically without user confirmation you should run the .exe like this instead start "Autokroma" /wait /b "PathToInstallerOrUninstaller.exe" /S

If you also need a command line installer for macOS, please contact us and tell us !

One license is for the same user on up to two computers not used at the same time. For example you can do macOS + Windows not at the same time, or your professional computer and your personal laptop not used at the same time.

Our installers are not viruses, but some AntiVirus software (Windows Defender, Norton AV, McAfee, Bitlocker etc.) sometimes produce false positive because of their probabilistic detection algorithms and the fact that we're using a very common library to create our installers. We regularly check our installers with VirusTotal.com too and there are never more than 1 or 2 AV producing a false positive. If that happens to you, please report this as a false positive to your AV software vendor ! You can disable the AV for the installation process, then re-enable it.

There might be a caching issue. Please restart Adobe Premiere Pro while holding the SHIFT key and flush the plugin cache in the new popup appearing.

Select "[A] Hap" or "[A] Hap Q" and export in RGB in the AE settings. Exporting in RGB+Alpha on AE (or ticking Export Alpha Channel on PPro / AME) will automatically switch the codec to Hap Alpha or Hap Q Alpha!

We recommend the open-source DJV_view media review software , it has RAM playback, frame-by-frame scrubbing and a lot of other features, check it out and install it! You can also use the latest versions of VLC Media Player.

Yes that's why there is AfterCodecs ! It doesn't need Quicktime (and never will) to run so you should be safe now ;)

Be sure you're using using H264 (and not H264 RGB or H265), with the quality slider < 90 and select YUV 4:2:0 (not 4:4:4 !). If it still doesn't work, lower the quality / bitrate and choose the H264 Main Profile

Same than the previous question about Quicktime Player : be sure you're using using H264 (and not H264 RGB or H265), with the quality slider < 90 and select YUV 4:2:0 (not 4:4:4 !). If it still doesn't work, lower the quality / bitrate and choose the H264 Main Profile.

You need to ask yourself what video player or hardware is going to read your videos files. Not all player accept all audio and video codecs, it could fail if one codec is not supported (AAC audio for example) while the video codec is supported. Not all player support all extensions / formats, even though the codec inside is supported (for example Adobe not reading .MKV files that contain H.264 video). Also, even if one codec is supported, your player might not accept some particular sub flavors of it, for example most H.264 players support YUV 4:2:0 chroma subsampling but not always YUV 4:4:4.

Be sure to set your AE project in 16 bpc, it will export to AfterCodecs in 16 bpc (even if you select "Millions of Colors" instead of "Trillions of Colors")

H264 is the standard / norm and x264 a software encoder that implements H264, faster and of better quality than encoders from Adobe and Quicktime

Not yet, sorry, but feel free to contact us to tell us about your specific needs.

There are some issues with H264 Hardware encoding on Apple silicon : Adobe UserVoice a To solve this, use our Exporter AfterCodecs that produces the same file on all platforms and all CPUs !

You can do that with AfterCodecs ! Batch Export Multiple Clips from the same Sequence in Premiere Pro and After Effects

Here is a good article to understand Render Templates and Output Module Templates. Note that AfterCodecs is an exporter only, and doesn't add any template to After Effects by default, so if you need a template using AfterCodecs, just create it on your own with your customized AfterCodecs encoding settings
