A7SII in low light setting questions

I am pretty new to photography and was using an A7S II with a 24-70 indoors with only some available window light. I wanted to use a fast shutter to capture motion, so I put the camera into shutter priority or manual mode (can't remember) at 1/1000 at f4.0 ISO 1000, though the image was very dark. What should I do in this case? What if anything could I have done without having any control of the available lighting? Is there anything else on the camera that could have been adjusted or would I need a strobe at this point?

Thanks.

Haha crank the ISO! That's the whole point of an A7S.

Go to 51,000 or something like that

As Romanv said "Crank the ISO!"

Thanks, I am new to this, so I didn't realize that I should have boosted the ISO that high...
1. So by boosting the ISO that would have resolved the problem? Does this affect anything else other than adding possible noise?
2. If I was not using this camera with the high ISO sensitivity, what other options are there from a general photography point of view? Bring in controlled lighting? Flash strobe?

Thanks.

It will add noise to the image, but it is still very pleasing to look at. Another solution would be to set the camera in a stable location and use a sloe shutter speed

I wanted to capture some motion, so I cant use a slow shutter speed unfortunately....

What motion were you trying to capture?

I would recommend using some of the semi-auto modes that the camera has to help you figure out what each setting does. I leave auto-ISO enabled pretty much all the time (especially when I had the a7S), with an EVF it's very easy to see if your camera is pushing to too high/low of an ISO and adjust immediately with the exposure compensation dial.

I would also recommend reading up on the exposure triangle and the basics of flash photography.
