I used the Sony VX2100

I wanted to make a smooth slow motion. I shot a lizard that could move very fast. I put the shutter speed at 2000 and it began to get a little dark in the viewfinder. I read it has a

Max Shutter Speed: 1/10000 sec

I then tried to slow it down in post but the picture came out normal and nothing was slowed down. Have I done something wrong or missed something?


I am confused because I am still learning about the technical side of Cinematography.

Slow motion and a fast shutter speed are two different things.
Basically, standard video only records 25 (or 30 in the US; I don't know where you are) frames per second. The only way to achieve true slow motion is to record more pictures per second and replay at the standard rate. Your camera doesn't do that.

I didn't buy the camera, I rented it. I am still learning. I recorded some footage with the Sony PD170 and it gave me nice slow motion. It was ok. What I am confused about is I thought if you ramp up the shutter speed you can record more frames per second. When I slowed down the shutter speed I got a nice streak line from cars at night.

I feel silly. I can't believe I got the FPS confused with shutter speed.

Most prosumer SD cameras that have been released somewhat recently will have an option to record at 60i for your framerate. Not sure about the VX2100 as I use an XL2 and DVX100.
