aerender SYNTAX ERROR: Illegal argument flag: -reuse

[renenijman]

When doing renders from the command line it seems that I can not get the -reuse flag to work anymore after After Effects version 2021.

Is this functionality no longer supported? Or am I doing something wrong?

It works when I have an instsance open of After effects 2021 or earlier and use this command:

"/Applications/Adobe After Effects 2021/aerender" -project "/Users/macbook/test.aep" -comp "main_comp" -OMtemplate "h264mp4"  -output "/Users/macbook/test.mp4" -reuse

But when I try this with After Effects 2022 or the llatest beta version:

"/Applications/Adobe After Effects 2022/aerender" -project "/Users/macbook/test.aep" -comp "main_comp" -OMtemplate "h264mp4"  -output "/Users/macbook/test.mp4" -reuse

It doesn't render and gives me this error:

"aerender SYNTAX ERROR: Illegal argument flag: -reuse"

Any help would be greatly appeciated.

Hi,

I am seeing the same error. Any help on this? Is this happening only on Mac M1 machines?
There seems to be no reference to this online. 

I am running the latest version of AE `aerender version 22.2x120`

Thanks

A temporary workaround for me seems to be that I can have the terminal script use an older version of aerender (in my case 2019) with the -reuse flag and if I then have an instance of 2022 open, it will reuse that instance.

I fear feel this might not always work down the road, so a fix would be highly appreciated.

Is there any official update on this? The latest stable and beta releases still seem to not recognize the "-reuse" flag anymore.

Hi @renenijman,

This issue has been fixed in After Effects 22.6 and later versions. If you continue to encounter an error when using the "-reuse" flag, please follow the instructions I posted here to reset the Apple Event permissions for the Terminal.
