Global shutter - can it emulate the soft shutter that the motion mount features?

[Karim D. Ghantous]

This probably has been answered before. But, am I right in assuming that you could in principle emulate the soft shutter feature of the motion mount with a global shutter? I imagine that frame rate limitations might come into it, if the process requires frame averaging. I am probably not thinking this through properly, but I still think it's a useful idea to look into.

Nope. Motion Mount was/is a sine wave sync with the sensor. It provided a Global Shutter-like mode as well as what I thought was really cool Soft Shutter useful for temporal aliasing related issues.

Komodo is an actual Global Shutter with none of the restrictions the Motion Mount carries with it.

You can do some motion tuning via higher frames and such these days, but straight out of camera there's no way to do it.

Not really related to the motion mount directly, but what is going on with the waveform in this? The footage feels "flickery" and the waveform bounces around. Adding post motion blur mitigates it, but is this a result of the sensor being global or just the usual high contrast perceptive artifacts you get with certain pan motions and such?

Recently saw a non-calculated pan with high contrast perform really badly on Queen's Gambit, I think in the flashback scene of the car crash. There's a pan there that in HDR 4K really just looks like a stroboscope.

But generally, does the global shutter in any way increase the high contrast strobe artifacts you get with certain motions or is this just a perceptive placebo feeling? Do we need to "think" in another way while shooting certain motions?

Noticed that pan in Queens Gambit as well, was really awful.

Pan strobe problems increase with bigger screen, higher contrast ratios and the actual speed of the pan. Rule of thumb is that you can swish pan or your pan need to take more than 8 second edge to edge.

Yes, this I'm aware of, as the example in Queen's Gambit shows the problem of. But the question is if the global shutter in any way changes any of this for the worse? That we need to be more careful or thoughtful of it, or if that's just a placebo effect after seeing some material I shot (like the one in the link)?
