Whats the diffrence?

What's the Difference between 60 Fields Per Second and 60 Frames per Seconds?

i notice that the HD1000 you get 720 with 60FPS and 1080 @ 60 fields per second....

Hi David,

In a nutshell, 60 fields per second = 30 (29.97) interlaced frames per second

A more detailed explanation can be found here...

In the pdf manual page 75 it says
1920x1080 60fps
1280x720 60fps
1280x720 30fps

Is the 720 60fps real 60fps or fields per sec?

The resolution specs for the camera are listed as: 1080i/720p60/720p30
The "i" next to 1080 implies it's interlaced and the "p" next to the 720 implies those resolutions are progressive.

Stoopid here.. are fps like faster shutter speeds on a SLR? Would you pick 60fps for sports - like car racing - vs. 30fps for filming an orchestra from the 12th row? Thanks.

Imagine video taping someone running across a field. Let's say it takes 10 seconds for them to get from one end of the field to the other. If you were recording at 60fps, there would be 600 individual frames capturing the movement (60fps x 10 seconds). If you were recording at 30fps, there would only be 300 individual frames capturing the movement (30fps x 10 seconds). The 60fps video would look smoother because there are more frames captured per second. Now if you were recording someone standing at a podium making a speech it wouldn't matter so much because there would be very little movement from frame to frame. Does that help any?

Oh, and to answer your question... Yes, it would be better to pick 60fps for fast moving sports.
