@towi 24L is deliberately set off to do that.
Can someone trial some real world filming on 720 and 1080i. Ive managed daytime stuff for both with much longer recordings on bushes etc... than peope are reporting. Trying to find peak limits.

Nothing is clear cut yet as there is a lot of testing still to be done, the i frames in the H setting produce bigger picture sizes and in the lab graph better. To the human eye possibly not a lot. In the shadows you can lift more detail out in post.

@driftwood

OK, lets say I was shooting indoors with the only movement being one or two characters. If my default setting was 24L in your opinion when would it be advisable to switch to H? For master shots? and keep mediums, close-ups and OTS - where there would be less screen space for shadows - in L mode?

I hope I am not coming across as too persistent on this issue. I do have a Sandisk 64 SDXC card but when filming narrative material it is very easy to eat up 54 minutes. Due to the time necessary to dump the card's content onto a hard drive (and from what I've seen the 95MB/s 64GB Sandisk card will transfer at a top speed of 38MB/s on USB 3 = aprox 28mins when full) I would rather not record information that is imperceptible.

Thanks again for your time and awesome work :)

@spacewig

You just answered you own question: "I would rather not record information that is imperceptible."

If you can not see the difference, you only need to satisfy yourself.

Driftwood's 24L setting is better than stock. You can't go wrong.
Use the 24L for event and docs.
Use 24H for higher production cuts where quality needs to be its best.

@proaudio4
Understood. But I can't help but feel I just lack the experience for now to see the difference. Given your name, I'll make the presumption that you'll understand the following analogy. Band wants to record drums for rock album. You could use the pres in your SSL 9K. Or you could roll out the sidecar of 1073's. You know there's a difference, and it's audible, but most people would never hear it. However, if you had to chose between running the kick or a bass through one 1073 you'd chose the kick and probably wouldn't even think about it if you were recording a casio keyboard through an SM58. The comparisons are strictly for the sake of illustration. I just thought that those in the know could impart their expertise by offering advice on when the gains made by the higher setting are worth the cost in bandwidth, when it is a consideration. (and if you own an SSL and some 1073's, well it's xmas all year round...)

@Strangways
That's the most obvious solution but one that costs $200... I was hoping to stretch the one I have now and use the savings for other gear.

@spacewig, trust your eyes. If it looks good to you, it is good. Don't let anyone convince you otherwise. We should not all be chasing gophers.

Thanks all for your advice.

Just used AQUAMOTION' ver 2.
24p with setting to H was oke, no problems.
but 720p 50fps did give a screen with, card to slow.
i have the Scandisk extreme pro uhs-1, 8 gb 45mb card.
The file was just 0bites in windows.
i was trying to rescue the file with RescuePRO Deluxe demo http://www.lc-tech.com/pc/sandisk-rescuepro-and-rescuepro-deluxe/
But no results :-(

to bad, still have the Sandisk Extreme HD Video 32 GB 30mb in order.
and will try it then again....

Hey,
i'm a New User of the gh2. I have two questions :

When i Set the Iso in 24 Cinema Mode to Maybe 640, the Camera says me during the Record "autoiso" is this normal?

And my Second question is about Correct exposure, should i Film through the searcher or with the LCD? and how can i judge the right exposure? in my Tests the LCD picture was fine but the final file was very underexposed!

Thx for your help ;)

@tobnyot

What utility do you use for formatting?

L not spanning on 30MB/s Sandisk 32gb, even after a low level format.

Image looks good, though!

Also of course it has A LOT to do with composition, lighting, set, scenery, wardrobe and color correction. Expect no magic there without effort. ;)
