Sorry to hear that Ken,

Yeah,..this is one nasty problem. I'm sure MANY people out there have jacked up 30p footage and don't even know it.

I can tell you that my camera just came back in today from JVC and it HAS been fixed.

I am now running Cam Version 1.11 and 30p @ 1/30 shutter is now looking GREAT!. It's true progressive and no longer has interlaced fields. Finaly!!

JVC needs to announce a recall on this camera so that people are aware!

Ship you cam back to JVC ASAP!

Case closed.

aaaah crap!

this just happened on my latest shoot, did it 1080 at 25p, stupid interlaced lines all through it!

i bought my camera from the states, do you think the local JVC guys will fix this?

Me too. Thanks for the info.

Hey Marty, did you get this sorted?
And if so, who by?
I bought mine OS as well, when this problem appeared, a while back now, I rang JVC service in Sydney and was told they weren't allowed to touch it. They did give me a number of an independent repair shop, but after speaking to them, they knew nothing about the problem or how to fix it.
I pretty much gave up on getting it fixed. Just stick to 1/50 shutter now, 25 would be nice to have available though.

I have posted before regarding this issue. I have firmware version 1.10 which came with my JVC GY HM100 when I purchased it in June 2010. This was the latest UK firmware update at the time and solves the interlacing when shooting in progressive issue. Current US versions of the camcorder have 1.11 which also solves this issue.

Please note that you will not be able to download either update. If you are having problems with the interlacing issue you will need to return the camcorder so JVC can update the firmware. Luckily for me I purchased my UK camcorder after JVC were notified of the problem.

Note that this issue was previously addressed by Mark Slocombe (CreationVideo) who posted the following back in September 2010:

''I've just been at JVC hq in London with Mike Turner, the chief engineer. He advised me that there is a software update that eliminates the problem where interlaced frames are recorded whilst shooting in progressive modes. It is a free update to version 1.10. but needs to be done by JVC.''

Like Mark, my camcorder, which obviously had the software update applied a few months before, has CAM Version 1.10. Arm is 1.05 and EEPROM is 052.

Hope this is of help.

I had mine updated 6 months ago by JVCPRO in Sweden.
Excellent service. Droped it off at the local pro dealer after a couple of emails with JVCPRO and picked it up 3-4 days later. Of course free of charge.
