Could sombody explain me what is the Split-screen problem of the JVC-HD100U camera that I read in some post?. Thanks.

I was going to direct you to JVC's official FAQ, but they have once again revised the text.

I am putting together a FAQ for this forum and will post it as soon as I'm finished.

In the meantime the short answer is that JVC chose a native resolution of 1280 x 720 (no pixel shifting) that is progressively scanned at 60Hz or 48Hz. The downside of the design is that power consumption is high and excessive heat is created when scanning a full 1280x720 60 times per second. JVC developed something called HSTR (High Speed Twin Readout) which basically processes 640x720 on the left side and 640x720 on the right side separately, and then re-combines the two sides. Splitting the workload left and right avoided the heat and power problem.
However, if the two image processors are not precisely calibrated, you may see a slight difference in overall gamma between the left and right sides of the image. This is why every HD100 is now going through QC before they ship to the dealers/end customer.

Most people have reported not seeing the problem on units that have shipped in the last two months. However, even properly calibrated units will show the split-screen in some extreme conditions. Flat, very dark images seem to be able to induce it. I have also found that flaring can induce the "effect."

Thanks Tim, I recently bought an HD100 and caught our attention when the cameraman was making me a medium shot for checking the skin color it does, we discover in the monitor that from the top to the midle of the screen the shot was darker than from the midle to the bottom of the screen.

1. Could this be the same SSE-Split screen Efect?
2. Is there a way to fix it?

Thanks

No that's not SSE. Is this a consitent problem? This sounds like a ND Grad filter. Maybe you had the ND filter switch set half-way?

thanks, Tim...I'll chech it up.
