1-Learn to focus manually.
2- If your camera allows, use manual exposure settings when shooting video because exposures will change as you pan the camera.
3- A good shutter speed for video is 1/50th second. That’s the “classic sweet spot”.
4- Set the ISO to 200 (ideal) – 1600 max.
5- Aperture setting of F/5.6
6- If your camera accommodates 24 fps video capture (Personal preference).
7- Avoid auto white balance at all costs. Instead, pick one white balance mode and stick with it throughout the video.
8- Use the camera’s neutral image setting; it will give you the most latitude for post production work.
