Template-hosts in config?

What is template-hosts used for in the config file and how?

        <video-mode />
        <filename />
        <width />
        <height />

It is used to run Flash templates in another resolution than the channel hosing it.

Only flash?
Is it also possible with HTML or do you have to make them to specific resolution?

In HTML you either do it in a fixed resolution or responsive. Flash was only fixed resolution and therefore this Template-host stuff has been invented.

That makes sense, thank you.
