GH3 frame rates
 
Being math challenged, the percentage thing is a mystery to me!

Can someone share a conversion of the percentages into actual FPS numbers?

Thanks!

Percentage regarding to what? Chip space? Battery life?

Frame Rate. What is the fame rate at the various percentage settings?

Re: GH3 frame rates
 
Are you perhaps thinking about shutter speed (rather than frame rate) as expressed in degrees (rather than percentage?).

For example, in the film industry, a 180-degree shutter means that the shutter is open 1/2 of the duration of a frame. Film frame rate is usually 24fps, so a 180 degrees means the shutter is open for 1/48th of a second. Not sure about the GH3, but on a GH2 the closest shutter speed to 1/48th is 1/50th.

If that's not what you're asking about, apologies... but can you please provide an example of the reference where you're seeing percentages?

In the GH3 menu, in video, there is a frame rate tab.

In the frame rate tab; the selections available are OFF, 40%, 48%, 80%, 160%, 200%, 300%.

These are variable frame rates. I think they are percentages of 24 FPS, not 30. But I'm not sure.

40% of 24 FPS would be 9.6 FPS.

Just did some quick tests.

The 80% is just barely slo-mo
the 40% is quite a nice slo-mo
300% is keystone cops territory.

So from my past experiences, the 80% looks like shooting 30fps and projecting 24 fps. Slight effect.

the 40% looks like shooting 48fps for projection at 24 fps.

Would love to know what these percentages actually translate into.

Page 185 of the GH3guideUSA.pdf says that regardless of other settings this mode sets 1080/24p at 24 Mbps with no sound.

Are you trying to say that whatever I set the option to, from 40% to 300%, I'm still at 24 FPS?

That is NOT what is happening. See my observations above or try it yourself.

No, I'm saying that the percentage change is in relation to 24 fps.
