The HD100 Sideways.

I was doing some split screen tests with the HD100. I'm not a tech. Just a concerned user trying to make the best of a defective camera. I have read that the split screen is cause by left and right sensors which are not calibrated correctly. However when you shoot with the camera turned at a 90 degree angle the vertical line does not turn horizontally. It remains dead center vertically in the middle. Also I'm curious on resetting my most recent HD100 with the firmware upgrade. The split screen is still very apparent even though JVC claims that the camera was thoroughly inspected. NOT! I'm curious to see if the camera reverts to a more prominant split screen effect. I've been looking at it for so long, as someone else mentioned. You still see it even when it's not there.

Oh well...anybody have any ideas on the split screen sideways phenomenon?
 
Okay, now that's just nutty... :cheesy:

Turning the camera sideways -- I'll have to try that! Good de-bugging technique there. If it's still a vertical split even when the camera's sideways ... well, I don't know what that says about it, but I'm sure it says something, perhaps the engineers could use that info.
 
I had a 3/4" deck once that was giving me trouble, but everytime, we bundled it up and got it to the repair shop it was fine and the problem went away. After going through this a couple of times, we just took the machine for a ride everytime it acted up and it was fine. Maybe you should take the JVC for a ride! :thumbsup:
 
I had a TV that would loose its tuning but when you wacked it really hard it started to work fine again... for a few hours.

And I can attest that this method worked well for Lacie Optical drives too. Thank goodness somebody else has experienced this. Everyone thinks you're mad - unless they're a parent who's placated a <18mo child by taking it for a drive too.

Okay, I tried turning the camera sideways, and the split stays perfectly vertical on the television.

As it should.

Turning the camera sideways doesn't make the split move, because the television is not also turning sideways. The camera may be filming sideways, but in relation to what's up and down in the viewfinder, the split is still occurring up and down. Then when it gets played on the television, up is still up, down is still down. So there's nothing odd going on -- it's doing exactly what it should do (related to why the split doesn't turn sideways on the TV).

So the split is always vertical on the camera ouput? I guess that would rule out the two SD CCDs stuck together theory....?
 
Well, it's never been a question of two CCDs stuck together, it's high-def CCDs taht are being sampled by two side-by-side sampling chips. And since they're side-by-side, the split will always occur from the top to the bottom (i.e., left half of picture looking different than right half). And that is relative to whatever way the HD100 is oriented -- the top of the viewfinder is always scan line zero, whether you rotate the camera or not...

What is JVC doing about this?

I bet. I haven't kept up with this situation, I've never been that interested in the JVC cam, but does this make the camera totally unusable or is it only a problem under certain conditions or settings?

As I posted in another thread, I tested a camera with no split screen. I could only see it using 18dB but very hardly visable. I tried to recreate some situations like the ones we've seen and there was no split at all. But this was an European model...
