"Unknown Error" occurs when opening an AVI codec configuration window

"Unknown Error" occurs when opening an AVI codec configuration window inside format options and pressing OK. Seems to only effect after effects 2024

Which particular version of AE 2024? 24.0, 24.1, 24.2.1? Do you have any other third-party codecs installed on the machine?

[Brandon356510351b0p]

Running version 24.1.0 build 78 currently. Yes the codecs I tested with are third party, the first codec I tested with is one that we make called "XPression Video Codec" and I tested Matrox DVCPro and Matrox MPEG-2 I-Frame.

I have a video showing the issue but, it seems I cannot upload videos.

I can't repro the issue locally but I don't have any third-party codecs installed. If you can link to a video of it, or at least try removing the third-party codecs and see if that's the trigger, that might help.

Here is a link to the video with the reproduction https://transfer.rossvideo.com/f/366474c62d26f7e6

Thanks. If you don't click the Codec Settings button, but just click OK in the AVI options dialog, do you still get the Unknown Error? 

[Brandon356510351b0p]

I do not, the error only occurs when a configuration window is opened and closed within the AVI options dialog.

Thanks. I'll get a bug written up and we'll see if we can reproduce this with one of the external plugins that enable the Codec Settings button. 

[jenkmeister]

Are you able to get me a copy or a trial of the XPression Video Codec so I can check this with your plugin?

@jenkmeister 

Sent you a direct message with a link to the codec.

[jenkmeister]

Thank you for the codec. I found what's wrong now. Checking back with the engineer who wrote the original code to see what we want to do to fix this. 

[jenkmeister]

A fix for this is now in the AE 24.4x7 beta that is downloadable on CCD. If you're able to download and test that version, that'd be really helpful to confirm the fix.
