Is 720p30 really progressive?

Hopefully, this information should put this topic to bed. It's not IN the camera.

However, it IS real.

It's real in any low frame-rate media. And, I buy the notion that it's not simply our eyes its our brain.

I think shooting at 1/30th to obscure the moving image is one solution -- but I think its better to shoot at 1/60th and shoot correctly.

For some (many?) the solution may be to wait for 60p HD. There is a reason why FOX dropped plans to use 480p30 and switched to WIDE 480p60. And, the JVC camcorders give you that option.

I plan on doing some more shooting with 480p60.

Hi guys, long discussion. I saw this double lines on skydivning footage (double roads), so I simply took a DV camera and filmed my computer monitor. Now I got it. The computer monitor is not synchronized to 29.76 fps and shows two frames mainly with an exception that from time to time a single frame is displayed. This monitor is a Samsung 1775W that is a HDTV also. As TV it is synchrinized with a video and everythig looks better. This would explain why those, who finally connected their HD1s to a HDTVs, were very impressed with a camera.
