Recommended shutter speeds for D850 video

I have just barely started trying video on my D850 (or any DSLR) on my last dive trip.  After a few days of frustration, I figured out that you can't just fix things (white balance) in post with MP4 files like you can with NEF's.  That at least got me something watchable once I learned how to set white balance.

Now I'm trying to figure out other settings to make my videos look better.  Specifically, shutter speed.  (I'm assuming higher speeds may help when panning.)

I shot my videos at 4k, 30fps.  I set shutter speed to 1/60th, which really helped keep the ISO low while shooting ambient at F8, but which didn't necessarily give me the sharpest results.

I know I'm supposed to 'see' motion blur in an expected way when setting shutter speed to double the frame rate.  For the most part I like my videos so far, but not so much when I move the camera from side to side.

Here's an example of one of my better videos.

I shot DLSR Video exclusively for years. What you are getting (one video) appears good for what you have. You mentioned ISO. What tip I got was to set ISO to auto with a max of 1600 and let the camera handle that. I stopped white balancing and went for the "flip" over red cayenne filter. I shoot mostly ambient knowing I'm giving up some color, but it is truer to life. The greatest challenge for us all is camera movement. I learned to shoot with the water movement instead of working against it. Getting the shot while making the viewer seasick is a bummer. I now skip those.

After years of whining, I moved to a used pro video rig. Sony video and Gates housing with wide angle. I got a 10,000 Lumen light that was a game changer (for me). Still use the red filter for ambient, 4k and 60FPS or 30FPS I set Gain (ISO) to auto with a max and also set Iris (f stop) to auto. Results are stunningly better. The heavier rig actually gives me more success with stability. Being slightly negatively buoyant is a plus as well.

Good Luck and Great Diving!

I'm no video expert, but I know what appeals to me.  This seems to have all been taken in one long burst of video as you swim around and look around the reef.  The videos that appeal to me, will string together clips with interesting action, like where the school of anthias swims across then close in and show your sea slug up close for example.  The motions are kept simple and pans are fairly minimal.   So might swim along behind the school of fish or other interesting action then cut to another section of reef with different action happening.

I think it's interesting doing that while you are down there swimming around and are free to decide what to look at and where to go, but if you are looking on the results on the screen , you need to keep the interest up. So I think editing together the interesting and steady bits will be worth a try.
