I think that is a much better idea...

My approach to this would be to first speed up the reinit with
by caching the scaled images. If that is not sufficient, cache
the channel resolution and aspect ratio, so that we can use a
matching dummy recording. If that is not sufficient, then start
thinking about things with negative side-effects like lazy
