If you get the film completely steady in the gate sure. But that’s not how the Kinograph is designed and not how most DIY scanners work. The Sasquatch is a special case, I’d say it’s atypical of DIY machines. If it’s steady in the gate in a DIY machine that means either very slow scanning, or you’re using a projector which holds the film steady. A projector-based scanner will still need a global shutter really since the film isn’t completely steady, at least not without some serious engineering to make it so. The steadiness in the commercial scanners is a result partly of the film being tensioned perfectly, in a projector gate there’s little tension so the film can move a little bit freely.
Engineering around the limitations of the sensor is what the old machines did and why they cost so much. Now you can buy a sensor that does what you want and is actually suitable for film scanning as it is.
