No, the PAL system has 50 fields per second. Each field is exactly 2/100ths of a second. A frame contains two fields.

The NTSC system has 59.94 fields per second. Much harder to calculate what’s going on when you flick between each field.

What I mean is, with PAL, you can sit there with your camera and know everytime you flick a field on its display it shows an image that is advanced by .02 seconds. When you flick each field with NTSC you are advancing some obscure value that is pretty hard to calculate mentally.

A practical example… lets say you video a race and want to know what time the second place getter got, the winner’s time pops up on the board at the track. Now reply your video and find the field where the winner crosses the line. Now count the number of fields until the second place getter crosses the line. Let’s say its 4 fields. You now know that the second place getter was .08 behind the first.

Now try the same thing with NTSC :frowning:

Ok, I see what you mean.
