After updating to Version 4.9.1, SeeMusic stops working when I try to start creating a video with the Render button. Updating to the current 4.9.3 update did not resolve this issue. I hope this bug will be fixed as soon as possible.
When I selected AV Pro in the Render Framework, rendering started successfully. I'm surprised that it was a simple cause. Thank you very much for helping me.
Is there any reason you want to use Basic instead of AVPro? I'm considering just removing the Basic render option. AVPro should do everything better and be more reliable.
Please send a screenshot of the Render Settings window.
If you currently have Basic selected as the Render Framework, choose AVPro instead and try rendering again.
I have the same problem which I didn't have before. It works to render videos with AV Pro though. Hope this get patched in an update soon.
