GH2 official discussion thread

Info about GH2 video encoder.

I got some raw GH2 footage from undisclosed source. Fully thrusted.
So,
1) GH2 has impoved codec.
2) B frames are present (so, 2 reframes now).
Stream structure as in camcorder.
3) CABAC is absent (about 10-15 less efficiency compared to camcorders)

Interlaced footage has declared 16Mbit video bitrate (same as GH1), video is not detailed, but average bitrate is 16Mbit. So, seems that quality estimator is also improved.

24Mbit native stream structure (declared video bitrate about 21.7Mbit, average about the same, maximum - 25Mbit)

P.S. Post will be updated soon with more info. Stay tuned.

Why can you have 24/25p in the wrapper as GH1

Why can you have 24/25p in the wrapper as GH1

and not 50/60p in wrapper as per GH2?:Drogar-Sick(DBG):

Is it conceivable that this is really 50p/60p in a wrapper.
 
Would it need to be 100/120i?

Would it need to be 100/120i?

ie the reconstructed frames? ie technically not feasible, hey, LOL.

Dissapointing then,
 
Vitaliy, what's the difference between having B frame and CABAC ?
Any chance we can have a look at this footage ?
 
ютюб конвертит файлы но не МЕНЯЕТ их фреймрейт
так что же это за агрегат которым сделали такое количество -23.810 ???
НЕ МЕНЯЕТ! ты о чем ?
ладно скоро сотру
======
обманул - не сотру, буду вредничать
еще раз для тех кто в танке - ютюб не меняет фреймрейт НЕ МЕНЯЕТ - а едиус понимает его как 23.810
нет таких монтажек чтоб понимали такое! и нет таких монтажек чтобы в такой фреймрейт могли его пересчитать
поэтому и спросил
теперь пусть банят))

It would be nice to have a faster overcrank (slower slo-mo). The 80% is just a reminder of what we can't do with it.
