Hi @hschneider –
I have not run into any gaps when rescaling the browser using Cinema. If you can send me a ZIP file containing a project file, along with your video files and poster image file, that recreates this problem I’d be glad to take a look at it.
Here’s an example of the Cinema Stack in action with its default settings for reference: https://elixirgraphics.com/test/cinema-example
The Cinema stack is not designed to act as a “hero” banner. I’ve run into problems with users grasping the “hero” banner settings in the Banner stack in the past, which makes me shy away from adding it in another stack. If this is something you need or want though then by all means employ the code you’ve written to do just that.
Out of curiosity, why stop at
90vh and not go to
100vh instead? In your example the last 10% looks like a mistake on the page, IMHO.
