So I've filmed a few things here and there using HDV24p and a tv mode shutter speed of 1/48. I chose that shutter speed, because it is what is said to be the proper speed when comparing to motion film cameras. I've noticed that I get motion blur when people move sometimes. I figured that the way to solve this is to use a faster shutter speed, as is what my research as helped me conclude.
Now, if I use 1/48th shutter speed for times I film conversations or just scenes without a lot of movement, then a scene later I use a higher shutter speed for a
foot chase scene or whatever with motion, will it look different than it should or is it common practice to mix shutter speeds as long as my frame rate stays the same?
