Almost every export with starlight_mini fails due to an codec error
Some parameter(s) may not be supported by the codec. Check FFmpeg command. - Current container (file extension) is not be supported by the codec. Try changing the file extension.
Where did the beta testing happen ? Error is reproducable …
The issue is the audio being stored in a WAV format with the AVI video file. Try swapping the audio mode on the codec settings tab to Convert instead of Copy and see if that works.
If not, you can try converting the source file to H264 using Handbrake and then bring back into the Video app for processing.
