Interactive video doesn't work

Goodmorning, I'm trying to create a lesson using H5P Interactive Video. If I try to upload a 10MB file it works well. If i try to upload a 200MB file, it doesn't work: the upload is ok but when I save the lesson, the round circle keep turning for a lot of time. When it stops, if I try to open the Interactive Video configuration, I only see a blank page. Can you help me please? I set 1GB as max upload file and max post size
