ffmpeg-templates VS kanshi

This is super off topic, but I also find working with video UIs frustrating for this reason. For my own needs, I have been working on a video editing tool that has a workflow more similar to web dev. E.g. describe changes in text files and render the final video on the command line. https://github.com/andykais/ffmpeg-templates

Without digging into you problem, i just let you know one options/tool as an addition: https://github.com/emersion/kanshi

This works, but after a reload of the config the configuration is gone. Then I found this discussion and changed the line to:

Kanshi is not exactly what you're looking for but i stumbled across this when I was writing the dynamic display configuration page.

You should use different scale factors on each monitor. You can do it in your sway configuration, or use something like kanshi that automatically applies different settings based on what is connected.

If this fixes your problem you'll want to apply this fix: Disable Laptop screen upon closing screen. or you can use something like Automatic display profile switcher when you connect your external display to switch it to while also disabling your laptop screen.

I also heard of kanshi for monitor configuration, but I believe there's an open bug where sway reload breaks kanshi config... which kind of defeats the purpose.

kanshi should be able to do it.

Assuming your connected monitors may change - you plug another one in and then you want to move workspaces the new output: kanshi can help you with that. You can tell kanshi to execute commands when it matches a profile.

For this you can use kanshi.
