Which mode should I use to shoot videos with DSLR?

Manual mode, shutter priority mode.

1. Use manual mode when shooting videos with SLR, and you need to manually control aperture and shutter speed. This mode provides greater creative freedom and allows you to adjust exposure parameters as needed. However, manual mode requires certain photography skills and experience, otherwise it will affect the exposure and stability of the video.

2. In shutter priority mode, you only need to control the shutter speed, and the camera will automatically control the aperture. This mode is relatively simple and suitable for novices. Shutter speed control is very important for video stability. A faster shutter speed can reduce jitter and improve video clarity.
