I was using a CRT display, so refresh rate isn't an issue like with LCD and Plasma.

One Solution

The ghosting isn't necessarily going to tape - it may be generated during capture. I had the same thing happen on two different editing systems. The GOP is 60 - in the case of 24P, there's a picture, then two frames of nothing, a picture, one frame of nothing, repeat. The editing system may be capturing tweens instead of frames. I was using CANOPUS and had this problem until I went through every single tiny bit of the setup and made sure everything from top to bottom was 24/720P AND that it was capturing the raw data stream (m2t). Then it was fine - no more ghosting, no more still frames that looked like double exposures. Not sure if this is your problem, but check this: pause the camera on one of the offending sequences and check the image on an external monitor. Go through a dozen or so random pauses. If you don't see the ghosting, chances are the frames are recorded properly on the tape, they're just not being captured properly.

JVC created a new flavor of HD compression for this camera. It's within the specs of HDV, but no other camera records data to the tape in quite the same way, so it's not surprising that editing systems aren't all tuned up for it yet.

Good luck!

I'm fairly sure I saw the offending frames on tape as well as after capture. It was mainly how the Dell monitor was working that highlighted the frames. Knowing they're not visible during playback on any other monitor, I have since been able to tune out this problem more or less. I'm using DVHSCap and it seems to be working well.
