[url="http://www.mandorlamovement.com/about/"]Mandorla – a feature directed by Roberto Miller in production now on the hacked Panasonic GH2[/url]

The new official GH2 firmware is out now, you can [url="http://panasonic.jp/support/global/cs/dsc/download/fts/dl/gh2.html"]download it at Panasonic here[/url]. Please be aware when you install it that any hacked firmware is overwritten and lost although one forum member at Vitaliy Kiselev’s site said he was able to roll back the hacked version 1.0 firmware again just fine with PTools and the new firmware doesn’t block anything. Take this with a pinch of salt until more people have tested it and if you need the hacked firmware for an important upcoming project don’t install this update.

Vitaliy says [url="http://www.personal-view.com/talks/discussion/1656/gh2-v1.1-new-firmware-with-25p-discussion-topic/p1"]here[/url] that it will be a while before the current hack patches are ported to the new official firmware update, which has a few new features.

The new update includes a 24Mbit 1080/25p mode for PAL GH2s (30p for NTSC cameras sold in Japan and the US) wrapped in a 50i AVCHD stream. It is a native 25p output and you just need to unwrap it when you transcode the footage like with the old out of the box GH1.Great for PAL GH2 users to finally have the choice between 24p and 25p for broadcast and pro work or mixing with footage from other PAL cameras on 25p timelines.

Some users are reporting that the gamma switch between live view and record mode has been fixed by the new firmware. This would be great if true since it is very noticeable especially via HDMI on a good monitor and it will make for more accurate exposure.

Woo hooo, been waiting for this for some time, time to upgrade my beloved GH1! What I am interested in is how this effects high iso performance.

I will upgrade my GH1 when they release a GH3!

I sold my GH1.3 for the GH2 but wish I’d waited because the GH2 is now available (w/Lens) for $699.00 Would have saved about $250.00!

How we unwrap the footage in 25p ?
FCPX import, informed me that its interlace…
I dont want to reencode and loose time.
Is there any other solution , like cliprwap ?

i tried premiere too… it doesnt work !

In premiere 5.5, right clip over m2ts 25 p file: Modify/Interpret Footage: Field Order: Upper field first. If you do the same process over 24p file, you get: No fields (Progressive Scan).
the same with footage from sony nex 5n @ 25p. No fields (Progressive Scan)

you can do two things in Premiere to resolve this. Simply drop the file into a 25p (30p) timeline and see if you have 25 (or 30) unique frames with no interlacing artifacts. You should. Alternatively, you can change it to progressive in this interpret footage window under the conform option.

Has anybody tried AF in video recording?

[Guest rsquires]

Well Premiere Pro CS5 brings it in correctly. 25fps no interlacing artefacts. FCPX on the other hand sees it as 1080i and forces an Upper Field playout which makes the picture look jagged and rubbish. There is no way in FCPx to change the way it handles the footage it seems. Not that I can see anyway

Great!

If memory serves right from the GH1 days you can also use Voltaic and JES De-interlacer to process the clips and remove the interlaced wrapper before importing to a NLE.

[Guest Andrew Reid]

There must surely be an option. I don’t use FCPX at the moment for reasons like this, it isn’t complete enough or reliable. Try JES Deinterlacer, it is free. http://jeschot.home.xs4all.nl/home.html

you can force FCPX too, to see it as progressive.
It works, just go to the info pane , and change the filed order.
And in fcpx prefs , change preview to high quality and then you dont see artifacts.
But , as in premiere too, it needs render again (if you put the footage to a progressive sequence)

Just tried it with 5DtoRGD to Pro Res then FCPX wants to play..

Just ordered my first GH2 which I’m thrilled about. Question, what does the High Bit Rate mode mean? Doesn’t the GH2 shoot at 24mbps AVCHD to begin with?

[/html]

[Guest johnspirou]

[html]

Now, you can shoot in 25p (30p in NTSC) (wrapped in 50i – 60i) and 24 Mbps … thats HBR

Has anyone been able to extract camera or film settings from the M2TS metadata?
