I changed the framerate today - can that make a difference? Its the only thing I did different from earlier

@dusx

I just retried with apple pro res and quicktime. Its all black

@dusx

I changed the framerate - Is that the same framerate that will show in OBS? If I can possibly record there in stead?

oh sorry, I did do that. But it doesn't work. I set it to Apple pro res 422.

I need to go to bed. I will check tomorrow in the morning before I leave. 

Please try setting your Output/Record Stage Settings, to use container 'quicktime movie' and codec 'Apple Pro res 422'

It is likely that the mp4/h264 codec was not allowing the ultra wide format of your blended stage.

like change the frame rate

 You can set the projects target framerate in the preferences. Open menu, Isadora / Preferences -> General Tab, Frame Rate/Tasks

here is a zipped filewalking-towards-peace-essen2-mapping-kopi.izz.zip

I know as plan B, that it should be possible to use OBS, I did it before, but only once. If someone has a good guide for using that with Isadora that might be helpful. Also how I do things like change the frame rate_:)

I have uploaded the file through file- upload, it uploads and shows the link. How else can I send the file?

 I suggest Zipping the file and attaching it. This should work. 
I will check to see if something has changed with permissions for .izz files.
