Flash Band Correction appears in both JVC camcorders the HM600 and 650, it’s an attempt to stop waisted unsightly frames on your video production especially useful for weddings where the constant barrage of flashguns can become off putting.
You need to go into the cameras menu system under “Camera Function” and you will see “Flash Band Correction” open this up to reveal on and off, it’s off in the default setting. Note : You will not be able to use this function till you switch off the cameras shutter.
Once you have switched it on you will get an ikon showing you that Flash Band Correction (FBC) is on but be careful especially at weddings every time you power down the camera the FBC reverts to the off position.
Here are some live samples of flash banding as you can see it corrupts 2 frames which is a nuisance but not the end of the world.
As you can see the frame is now over one frame and is mainly white (flash) so it does compensate for the loss of 2 frames which is far more pleasing to the eye. The JVC GY-HM600/650 is one of the few camcorders to date with live flash band compensation built in saving you a ton of time correcting it in post.
