I just released a new version, that should help with this:
The [object Event] error means the video file could not be found or loaded. Please check:
- The file is inside your project's movies/ folder
- The filename in the command includes the extension (e.g. myvideo.webm not just myvideo)
- The filename matches exactly, including capitalization
- The file is .webm or .mp4 format, other formats like .gif or .avi are not formally supported, you can do gif but you might encounter issues, best to convert to webm.
