How to Use Shutter Speed in Video on DSLR Camera – Exposure Tutorial and Comparison
If you shoot video on your DSLR camera at least occasionally, this information will be useful for you. We have the examples to show how the exposure (or shutter speed) affects the video quality.
The first thing a beginner user thinks: shutter speed parameters just make the image of the video darker or lighter. But this is not the only thing that it affects.
The easiest way is to draw an analogy with photography. The lower the shutter speed is (i.e., a higher exposure), the more a moving object will be slurred on photos. And conversely: the higher the shutter speed (ie, lower exposure), the sharper the moving object will be. When shooting video, everything is the same. Every single frame will be more clear and sharp, if the shutter speed is set high (e.g. 1/100, 1/1000, etc.). More pictures will be blurry in terms of shutter speeds from 1/30 to 1/80.
These are stop frames from videos that were taken with different shutter speed (exposure):
But the most important question: which shutter speed is the best for video capturing?
Unfortunately, the answer to this question does not exist.
On the one hand, people got used that a sharper and clearer image is the guarantee successful photos. But too sharp and clear image in the video makes the motion look not smooth and ragged.
Check out the video comparing the movement in the scene at different shutter speeds:
The movement in the frame with 1/30 shutter speed looks most similar to how the human eye conceives the movement. But, for example, drops, which are falling down, can be seen the best in the exposure of 1/800. So choose the shutter speed that you like in each separate case.
It should be noted that while shooting video at lighting interior, the situation with the shutter speed is a little different. Some common household light bulbs twinkle. LED-lights and fluorescent lamps twinkle most often and most strongly. A conventional light bulbs flicker least often. They twinkle so fast that the human eye will not notice. If during the video capture you set the shutter speed to 1/30, the camera will not notice this too. But if you change this value to 1/80, 1/100, etc., then black horizontal stripes may appear on the video. You have to remember that or just shoot video at 1/30 shutter speed, if you are in a room with interior lighting.
