Sure. It's a very broad question but...

Learn to shoot static first. Biggest mistake I see people make when they move from photo to video is moving the camera without intention. Master the basic size of shots - wide, mid, closeup - with a variety of stills lenses on a tripod (or in hand with good in camera stabalisation).

Then learn the basic moves - ped, pan, track etc. If you're moving, think about how you're stabalising your camera - gimbal, shoulder rig etc. Most DSLR's do not have good enough stablisation to allow movement without artifacts.

Make sure you understand your camera. For photos you have much more leeway in post. For video I'd recommend always shooting at the camera's native ISO, at 24/25/30 shutter speed, and keeping shutter angle at double the shutter speed (or 180 degrees).

Don't change settings during a shot (other than focus). Set everything to manual, get your ISO, white balance, shutter speed or angle right, and leave it at that for the duration of the shot. If the lighting changes in the shot, your settings should cover the whole extent of the lighting for that shot.

Think about each shot as an image. i.e.: Don't try to catch everything, but focus on a detail, or framing, just as you would with a photo. If you're filming people, how they sit in the frame in relation to the background and other people (how large they are in frame, how they're blocked, whether they're enclosed by foreground detail etc) determines how we see them.

Just focus on all the basic photography stuff - rule of thirds, colour theory, bokeh etc. People just get overwhelmed when they switch to video, but the same rules apply. It's really just moving photographs after all.

Movement is in time, think about a nice frame of a railway line in a landscape - then a train enters and passes through it. Movement is everywhere - water, reflections, shadows, animals. Find a strong frame in nature or the build environment, that has movement, or will have movement passing through it and shoot that.

Then start thinking about how shots connect together. Even B-Roll tells a story and has a rhythm. Wide to closeup, big object to small object, matching motion between shots, directing the viewers eye as it moves across the frame. You're always telling a story, so when you get 'coverage' try to have the story you'll tell in the edit in mind. If you're capturing a place, whats a wide or ultra wide that gives us an emotional impression of the place. What are some details that colour it in. Whats a change thats occurring that ads movement life and purpose.

Basically it's about intentionality and choice. Whats the feeling you're trying to convey and which shots convey it best. A good exercise is trying to shoot a happy event in a threatening or disturbing style, or vice versa. Here's an example where I shot and edited a St Patrick's day parade in a nightmarish style - https://www.youtube.com/watch?v=lpj-fK8obPI

Think in terms of the final video or film rather than individual shots. That's the equivalent of the finished photo.
