Question Unity Recorder 2.5.4 on Windows keeps sending an error within the ProRes plugin scripts.

Can you please provide us with screenshots of the Recorder Window and a copy/paste of the console messages?
All the ProRes options work in Windows and we've tested 2020.2 extensively.
One other thing to try is to run reimport all by right-clicking in the Project window. This will reimport all the packages and could take some time but it might reset any operating system migration issues.

 

Also try closing the Recorder Window and opening it again. I think I saw this once if you upgraded the Recorder package while the window was open.

 

Your Windows project is running macOS code. Reimport should fix it. Otherwise, remove the package via Package Manager and reinstall it.

 

OK try this:
* close your Unity project and C# project
* open your Packages/manifest.json file and remove the line that includes com.unity.recorder
* delete your Library folder
* reopen the project and add the Recorder package via the Package Manager

 

Also, is this a Windows VM on a Mac? It shouldn't make a difference but I'm curious as to why the macOS preprocessor directives identify the project as running macOS standalone.

Code (CSharp):

1.  
2. #if UNITY_STANDALONE_OSX
3.             // Ensure that this codec format is supported, because on macOS we depend on AVFoundation in the OS
4.             System.Text.StringBuilder sb = new System.Text.StringBuilder(128);
5.             bool supported = ProResWrapperHelpers.SupportsCodecFormat(nCodecFormat, sb, sb.Capacity);
6.             string sSupported = sb.ToString();
7.  
8.             if (!supported)
9.             {
10.                 Debug.LogError(string.Format("Could not create file {0}: {1}", _rawVideoFilename, sb.ToString()));
11.                 _encoderPtr = IntPtr.Zero;
12.                 return;
13.             }
14. #endif
