HM700 & 24p

Let me start by saying that I have shot a lot of film in my day and know all about the limitations of shooting at 24FPS. But, this JVC700 is the first video camera that I have had that shoots at 24p. My problem is that my images look like I have some kind of strobe effect on. Movement within the frame is jerky which becomes magnified when panning. I am shooting at 720/24pHQ with the shutter at 1/48 and the strobing is easily visible in the viewfinder as well as the lcd. When I even put the shutter on auto (which should be 1/48) still strobing. I have gone through the menus a dozen times trying to find some setting I have weird but to no avail. I am looking for motion blur not motion strobe in a 24p camera setting. Am I asking too much? I have seen some beautiful footage shot at 24p with video cameras with nice smooth motion. I am hoping this is operator error and not a limitation of the camera. Thanks for your help.

Experiment to Try.

Try shooting at 30p and then conform to 24p via Cinema Tools on Mac, Not sure what to use on a PC.

I see it also on recordings the strobe effect,
on LCD-TV it's visible, but on my MacBookPro it
looks really smoth, but on TV I don't like this,

720p30 and p60 looks really better, then
the 720p25 / 720p50 standard in Europe/Germany

I say it's probably your HDTV or monitor. 60hz monitors and HDTVs are the biggest culprits. Probably why 120hz HDTVs are the rage. Makes movies less stroby and more like the experience in a theater. I control the strobing on CHEAP or OLD LCD HDTV (Sony Bravia ) by just panning a little slower or faster. Can't wait to get a Samsung series 6 LED, but I'll keep the 60hz Sony to use as my monitor to insure I'm looking good with medium to low end HDTVs for the future.

It would be interesting to compare a panny dvx100b and jvc at the same time and same moves to see if it's the camera or monitor. Hey I have been wrong before in my life.

Here is your comparison: YouTube - Climbing Porn. Mostly shot with DVX and HD100, only one scene incorporated from HM100

I had the same impression when, after many years of shooting film, I began shooting 24p with my Panasonic HPX500... I finally (at a contributor's suggestion) reset the shutter to 220 degrees, and have been happy with the result (I've been shooting with that camera for nearly 3 years now).

Is it possible to do this with the JVC?

Curious, because I'm considering getting one.
