Projector corner adjust versus Isadora
-
Just wondering from a performance and video quality perspective, whether its better to use the projectors corner adjustment, or to clear all the keystone settings and use Isadora's calibration tool instead? Or does it matter?

What do you mean with calibration tool, do you mean IzzyMap? Double clicking the projector basically?

My gut instinct is that performance-wise there'd be very little difference in terms of how hard your computer needs to work using the physical beamer's keystoning vs using the keystoning in Isadora (keystone actors, IzzyMap, Stage Setup, etc.) but that's just a guess. The only thing I can think of is that doing the keystoning using the physical beamer's settings should theoretically be slightly more efficient because that "work" is being done by the projector and not your computer, but again, I'd be surprised if you compared the two methods and found any meaningful difference in terms of efficiency (though I could be wrong).
Personally I'd lean towards doing it in Isadora since it's more convenient to be able to all the keystoning for all my physical beamer's from one place instead of needing to use remotes for all of them, or a different browser tab (for projectors with browser-based controllers), or use PJLink, ArtNet, or some other kind of commands over a network. I'd also prefer to be able to see what I'm doing and have more individual control over each corner, both of which you can find in Isadora and are less likely to be able to do with the physical beamer's settings.

I like to get it as close as I can on the physical projector and then fine-tune it in Isadora. I think this is a personal hangover from the days when it actually did make a difference. Also, though, when you're using a lot of outputs I can see that the cumulative load might be significant?

Yes, now that I think about it, that's what I always end up doing as well. I was thinking about it too much in terms of A vs B and which is "better" as that's how the question was framed, but the real answer is what you said: the ideal workflow is to do A first, then B.

Don't know if this still is true, but I had the experience with some pro grade Panasonic projectors, that the geometric functions added some latency to the stream. But I guess, this was only true for more complex corrections with the optional warping board. Anyway, for latency sensitiv setups, this might be considdered / testet.
