LPowell: "Your claim that a 1080p60 frame requires less bitrate per frame than the same frame size at 24p or 30p is true only for long-GOP recording formats."

Vitaliy_Kiselev: "It is true for any actual modes used in actual cameras. as 1080p60 mode is using same 0.5 second, 30 frames GOP."

By "actual modes", you're evidently referring to the stock GOP-lengths and bitrates of the video modes in unhacked Panasonic cameras. But as I'm sure you understand, what most of us are interested in is how well these cameras will perform with short-GOP, high-bitrate hacks. My point is that regardless of how these modes are implemented in software, in practice they behave effectively as two separate encoders: 24p versus HBR/FSH/SH. The bottom line is that the 24p encoder modes can be hacked to operate at significantly higher bitrates and quality than the HBR/FSH/SH encoder modes. And if the new 1080p60 modes are built on extensions to the HBR/FSH/SH encoder, I expect it will share the limitations of that encoder as well.

PTool patch settings for the 24p encoder are completely separate from those of the HBR/FSH/SH encoder.

And? 720p settings are also separate, except bitrate (and bitrate is the same only because this routine is written as such, not because encoder). It does not mean that encoder is separate.

Frame rate is separate, and settings are separate. But encoder itself is the same.

Your claim that a 1080p60 frame requires less bitrate per frame than the same frame size at 24p or 30p is true only for long-GOP recording formats.

It is true for any actual modes used in actual cameras. as 1080p60 mode is using same 0.5 second, 30 frames GOP.

None of Panasonic's recent camera models include the GH2's 1080p24 encoder, and in my view, that rules them out as upgrades to the GH2. The 24p encoder is effectively a completely separate AVCHD encoder capable of sustained bitrates exceeding 150Mbps.

This statement is 100% false.

• All of latest Panasonic cameras include 1080p24 encoder (but not the necessary sensor modes :-) )
• It is not separate encoder, and all the difference is more related to frame rates and other encoding parameters

encoder is in practice limited to about 100Mbps peak bitrate, and I expect that limit to apply to the G5's 1080p60 video mode as well.

1080p60 requires less bitrate per frame compared to 1080p24 or 1080p30. As for interframe codecs you have much smaller changes and much better changes tracking if use higher framerates.

@Manu4Vendetta

Check first post :-) I try to update it from time to time.

@mpgxsvcd - You cannot forget a major difference between this G5 and the GH3 (or whatever they are going to call it)... the weather sealing. For some of us, that is huge!

Just imagine how AMAZING flower footage is going to look in 120fps!!!

(Not to mention the cat, the angry girl friend, the bored kids at the park, ...the possibilities are ENDLESS)

G5 may have manual controls for video.

"Does this have 720p 120?

Nope. FZ200 has it."

LX7 has it as well.

Is electronic shutter the same as global shutter? It is my understanding, an electronic shutter reduces the DR over a traditional shutter.

Did I miss something?> Does this have 720p 120?

Is it just me or does the G5 look like a GH2 without the multi aspect ratio sensor, without the external controls, without the manual movie mode(Easily fixed by VK), and without the few extra megapixels?

It does seem to have a lot of things I wish my GH2 had(HDR, AFF, single point focus, silent shutter with RAW, 1080p @ 60 FPS, 720p @ 120 FPS, the zoom lever, taking stills while shooting 1080p video....etc).

I seriously am not sure what they are going to put in the GH3 that will make me want to buy it over the G5. I am sure they will come up with something though.
