What;s ‘Flash Band’?

[Ronnie Martin]

It is the band you get from a flash still camera or a strobe going off during your shoot when using a cmose camera rather than a ccd camera.

And it’s because a CCD sensor gets scanned all at once whereas a CMOS sensor is scanned from bottom to top over time, or progressively. Sometimes a camera flash will be split between 2 frames, hence the ‘banding’ terminology.

As an aside, I actually prefer the banding over the complete frame blowout because you can at least see some of the frame. I’ve never had a single person complain about flash banding, which leads me to believe that the shooters/editors get more freaked out about the issue than the end user does.

I totally agree. Actually, whether it’s banded or full-frame makes do difference to me. They’re both just as annoying.

When there’s a lot of flashes going off at once, it can get quite annoying, aesthetically.
Probably because our eyes are used to the way CCD’s capture flashes. However, the good thing
about Sony XDCAM EX, is the Flash Band Compensator works very well. The clips end up looking like flashes caught on a CCD. I only wish Flash Band Compensation was done automatically, in the camera’s circuitry, like the Panasonic DVX 300 apparently does. That said, at least XDCAM EX has a fix with the Flash Band Compensator, where many other cams with CMOS chips do not.
