Issue generating transparent background videos

[PaulThbt]

Greetings,
I'm trying to generate a video with a transparent background. I understand in this case that Manim generates a mov instead of mp4 which doesn't support alpha channel.

Here is my issue : I ran "manim -t main.py myScene" but I'm unable to read the generated mov video with a mov reader.

I can read mov video with no problem after using for example "manim --format=mov main.py myScene" but for some reason transparent background mov videos don't work for me.

Does someone have a idea to solve my issue ?
Thanks for your help!
