Adjusting gain at DVinfo.net

Jeff Troiano · November 15th, 2011, 09:34 PM

If this is possible, I haven't figured it out Any way to adjust gain, other then the 3 way selector switch? I'd love to be able to scroll through the different gain settings by dialing the wheel. Kind of a pain to have to go into the menu and assign the high, medium, and low values.

Thanks,
Jeff

Currently that's the only way to do it. You can set the gain to auto mode and it will float. Useful in certain circumstances.

Sony should be able to do it with a firmware change, but will they and when?

I emailed and asked them to add more frame rate control in S&Q. They replied back that it was difficult to do in an AVCHD camera, but there engineers were looking into it. They also said that was a request they've gotten a lot for. I should have asked for better gain control also..lol

I guess with traditional video cameras we've only flicked in gain when wide open and not enough light. The FS100 with it's hi ISO ability changes the paradigm a bit so that requests like this make a lot of sense.
Auto ISO might be a good enough option though, especially if the camera meters accurately or even consistently so you can offset it with exposure compensation (AE).

Almost all Sony cameras including the top professional models will only give you a choice of three gain settings at a time, and all are selectable in the menu. This is common for other brands, as well.

It's always been the standard way of doing it on ENG cameras, but the gain have never been so usefull than on today noise-free large sensor cameras. The best implementation of gain I ever seen is on CANON XL serie of cameras. The physical switch on the body alowed any gain setting from -3 to + 18 is 3db step, plus a button and a wheel to manually select any gain setting in 0.5db increment. Nice!

On the FS100, in the menu you can top the auto gain setting to 0 db. This way the gain button is your 0 db setting, and you can set 3 other values on the switch.
