Can someone point me to the procedure on how to mask pixels on my GY-HD100?

Thanks
Randy

Press the Focus Assist button and Menu/Status button at the same time for at least 5 seconds. You must be in HD 24p mode for this operation.

You see an advanced menu where the second line says CAMERA1. Move the cursor down and push the shutter wheel to enter that menu and now you have a list with the sixth item being PIXEL COMPEN. Move down to it and select that item, the word CANCEL blinks. Change it to EXECUTE and push again. It takes about 10 seconds or so to perform the operation and then tells you to power off the camera. You are done. Make sure Focus Assist is now OFF and exit 24p mode if desired.

Forgive my nubishness, but I'm not familiar with pixel masking. Searched google and wikipedia... could someone explain it to me or point me to an article?

Greatly appreciate it!

With CCD cameras sometimes you get a "Dead Pixel" or 2 it seems to happen more on these GY-HD100s than any other camera I ever used. The result is a small dot on the image that looks like dust that of course cant be removed. Fourtunatly JVC has built in a feature (that I dont think were supposed to use) that will mask these dead pixels essentally removing them. It works well, how many times and for how long has yet to be determined.

Thanks Randy, haven't come across this yet, but definitely good to know!

no, jvc has our blessing to use it.

I got the instruction from them.

and it was estimated this could be done many hundreds of times over
with no issue at all.

frankly its one of the best features of this camera, I have (my bad luck i guess)
had sony and canon cameras both have hot pixels and when it costs around
1,000 to fix it, the advantage of pixel masking on this camera becomes clear.
