    Only works en after effects 2023? or other like 2020,2021,2022? thanks

    Hello. The reason is that After Effects only outputs MP4 natively and without plugins from this version onwards. But if you install a plugin (like AfterCodecs) to output MP4 directly from After Effects then you can use it in any version. Cheers.

Maybe in the future we'll add an option to output with Adobe Media Encoder, but we don't have plans for that yet. 
    Cheers.
    I understand, of course, I can natively output mp4 since I use aftercodecs that allow me to do so. In this case, even if I can output mp4 from AE, it won't work?
  • Gato ScriptsGato Scripts
    Yes. With a plugin like this it works. You would only have to edit the included Output modules (names MP4AC_RGB and MP4AC_Alpha) and change the native MP4 CODEC from after to your plugin's codec.

    Will this work on webm files with an alpha channel?
  • Gato ScriptsGato Scripts
    Hi. It works with any format you can import into After Effects. If you can to import webm into AE. But it is worth mentioning that my tool is for output and not input. OK? 
    Cheers.

    Is it possible to convert to mp4 with alpha only from mov or png and etc files? I would like to output to mp4 with alpha from the first project file, but it doesn't seem to work. It would be great to be able to output to mp4 with alpha directly, instead of having to encode the motion using shapelayer to mov and reimport it to mp4.

    Hello Lee.

    I didn't quite understand what you asked. But it sounds to me like you want to convert alpha video to MP4 files with an alpha channel embedded inside.

    But this is not possible with the MP4 format. Our tool allows this in the only way possible. Splitting the video into 2 MP4 files (RGB and Alpha) and putting them back together into a composition.

    All within after effects and automatically. From any video format and image sequence.

    Thanks for the answer. I realized that mp4 doesn't support transparency. In premiere pro, it's easy to do with trackmats. So is there any way to convert the composition directly to 2 files(mp4 rgb and mp4 alpha) without encoding to mov and converting to mp4 through a plugin? I have to do it twice to convert to mp4 again after outputting from after effects in mov.

    Hello Lee.
    Now I understand. During script development we considered adding that it would be possible to convert compositions as well, in addition to video assets.

    But we gave up when we realized that this could generate a lot of support tickets and complaints.

    The reason: is that unlike simple videos, in compositions you have the possibility to activate the "collapse" feature of the layer, which allows internal elements of the child comp (3d layers etc) to come to the parent comp. But when this child comp is replaced with a simple video, all these elements don't happen.

    I believe that many users have this awareness. But many may not. And this second group is the ones that could have problems and then complain to us. So this is the reason.

    Solution:
    But you can easily get around it like this:

    1. Create a new output module in some format that supports alpha (MOV animation etc), but set the following parameter: Main Options > Post-Render Action and choose: "Import & Replace Usage"

    2. Render your compositions using this Output Module. And your comps will be automatically replaced by the rendered videos.

    3. Now you can use our MP4 +Alpha Converter on these videos effectively.

    If you have questions or problems, just talk.

    Hi,
    MP4 + Alpha Converter does not work with After Effects in French, only with the English version...
    Is it due to the Demo version or is it normal that it only works with the English version?
    Thanks

    Hello.

    Thank you very much for your feedback. It is very important to us. You are the first user to report this bug in our script. We took great care to ensure that the script was universal and independent of the After Effects language.

    Complaints about this script are usually due to a malfunction caused by its incomplete installation. Please check if the output modules called "MP4AC_RGB" and "MP4AC_Alpha" exist in your AE installation. If not, this may be the cause of the problem. To fix it, watch the installation tutorial video (in the script's help and on the store page). It is simple and fast.

    We are currently creating a routine in the script to identify and alert when the installation is incomplete. In order to improve the user experience.

    Best regards,

    Hello,

    Yes, it's weird...

    It works on the same PC with After Effects in English but not in French, same configuration and MP4 + Alpha Converter installed the same way as in the tutorial...

    I'll check it out and let you know.

    Thanks
