D750 Time-Lapse Movie shutter speed

Under normal circumstances your playback will be 30FPS (29.97) and you need to figure out how long you wish for your sequence/es to remain on the screen. You can (eventually) edit your footage by removing frames (every other one) and that will give you faster rate, but it's also bit convoluted. Perhaps there is an app for that ?

If you are shooting once every 5 sec, then your shutter can be way slower/faster than 1/25sec (up to 4 sec slow) if you desire. Several months ago I've shot several sequences 3 sec apart and the clouds moved rather fast. Depending on the subject, but 5 sec intervals could create bit of keystone cop effect. Hope you are making some tests, first.

You may have to look at your manual how to set things up. Once you play the shots together = a movie. I'm assuming the time lapse will work similarly to my D610.

Thanks for the thoughts but that's my problem. In time lapse photograph mode I can select 4 sec, but in time-lapse movie mode I can't see how to do it. I can't find it in the manual. The shutter speed seems to be limited by the frame rate of the final output movie.

As I indicated, do test your rig. I just set up exposure of 1/250 - F6.3 and ISO 800. Ha, it just as well could have been 4 sec - F16 and ISO 64....depending on light conditions.

Next step

Went to Interval Timer Shooting (in menu) and set up the interval. Also, the Time Lapse Photography has to be properly set and engaged. Once the camera starts clicking....it's good to block the viewfinder (dark cloth over it is sufficient), to make sure you're not getting light through there. Just prior to that, you can peek into the finder and see that the camera is firing the exposure you determined. I had a bit of an issue overriding the exposure, which I initially set. Nikon send me some info how to tweak it, since you'll not be able to adjust the shutter or aperture during the shoot.....no idea what I have done with that email. I should add, that if you'll use legacy lens/es for this project, you will be able to adjust the aperture, since there is no electronic connection between the camera and the lens. If you will adjust the aperture, it should be in a v. small increments (1/2 or 1/3rd F-stop).....otherwise it will show up as you play it on the screen. By the way, cinema lenses (rent ?) don't have clicks; therefore, and are infinitely and smooth to adjust.

Next step

Once you shut down the camera, make sure you play back and see what you've recorded on the memory card. The movie will play automatically @30FPS, tho you could have a different prompt on your rig (?).

Again, testing will reveal whether your exposure is desirable and everything works according to settings....and most of the functions and settings should be done in manual - that's my approach. Anything "automatic" will introduce a variable/s that may deviate from what you desire.
