demo error

[junedgar]

Thank you for your great job!

When i ran the demo with err:

 File "/Users/edgar/conda/envs/py36/lib/python3.6/site-packages/kivy/lang/parser.py", line 591, in parse_level
     raise ParserException(self, ln, 'Invalid class name')
 kivy.lang.parser.ParserException: Parser: File "<inline>", line 22:

      20:    		name: "screen2"
      21:    		source: "iris.jpg"
 >>   22:    <MyScreen@Screen>:
      23:    	label_text: 'Hello'
      24:    	md_bg_color: 1,1,1,1
 
 Invalid class name 

Another question:
How can I save the result as mp4?

Hi, glad you liked it :)
Were you able to fix this? I'd suspect there's some error in your kv file. If you still need help, kindly share your code.
