Fracking with a GH2

Felix — Fri, 12 Aug 2011 12:53:40 +0000

Thought I'd tackle an environmental issue and a broadcast example of the GH2 in action. This Fracking action was shot on a standard GH2 using a 14 - 140 with exTele using 720 x 50p (I So need PAL) Video footage was broadcast by ITN and the BBC. Any advice on getting a stable 720 x 50p setting?

GH2 + H4N on Gini shoulder mount rig with Ruige 5" monitor

GH2 hack - where in menu do I switch between PAL and NTSC?

paralion — Sun, 07 Aug 2011 20:23:15 +0000

So maybe I am just dumb, but i cant find a menu entry to switch between PAL and NTSC after I hacked it...
Can anybody tell my where I find this in the menu?

thanks a lot,

How long will my relation with panny last?

luax — Fri, 05 Aug 2011 20:23:58 +0000

Something in the vein of luxury problems.
I found myself breaking my head over what road to go when it comes to buying into a (new) lens system.
As a PAL native and I felt a little 'put off/betrayed' by panasonic because of the PAL related issues when it comes to the our beloved gh2.
It raised pherhaps completely unnecessary questions like: Will I stick with lumix for the next couple of years? If not? Is it wise to infest a lot of money into a M43 system?
Since I feel that panasonic abandoned me and my PAL pals a little, will I stay faithful to them?
So my question is, what would be a good way to go lensewise that does well on the GH2 but could also soften divorce procedure when going into a potential new marriage in the future?

TrusMT T2 Follow Focus Review

Hunter_H_Richards — Fri, 20 May 2011 13:36:38 +0000

Its been 4 weeks now since I got this thing but ill start from the beginning to make it more interesting:

I was looking for used follow focuses on ebay for dslr use- to my surprise I saw an Arri Mff-1 look-a-like followfocus for sale brand new $399 by "trusmt". $399 sounded way too cheap but after looking at pictures from their website, it felt low enough risk give it a try, keeping a realistic view that if it was only 1/4 as good as the arri I would be happy with it for dslr use (going on $399 vs $1600 for the arri).

It showed up 2 days later in a pretty little box with precision cut foam for holding the goods (wish I still had this to take a photo of the box but I threw it out when we moved a few weeks ago, I was impressed though)

Contents were:

1x Trusmt t2 follow focus http://trusmt.com/proview.asp?id=44

4x Gear rings (4 different sizes)

1x bag of tools and extra screws

1x trusmt catalogue

First reactions:

Visual build test:
I picked it up and looked around the unit for signs of poor manufacturing, I was amazed how well it was made, very solid and couldnt see with my eye anything showing poor work. Colors and anodizing looked nice too.

Gear rings looked good- reminded me of red rock micro (i dont really care much for these but they work and were included "free")

Follow focus feel test:
To make it fair, I have used every mechanical Arri follow focus from ff1 to ff4, including the mff1, the lwff, ect- most chrosziels, as well as most "affordable" ones like redrock/cavision/cinevate- I got spoiled on the arri's and chrosziels for sure.

I spun the trusmt followfocus wheel to see how the gear box felt, It was very well dampened and actually felt good (possibly too well of dampening, but ill get to this later)

"Wow, I cant believe this was $399" I thought

Two handed "play" test:
(no not what your thinking pervert)

I grabbed the handwheel with one hand and with my other hand, i held the drive gear to see how much play there was. it seemed like too much play- then I realzied I needed to tighten the drive gear screw and after that it was only maybe 2mm of play? Didnt take an accurate reading but what ever it was it was very close to the more budget friend followfocuses like redrock for example and much better than the origional redrock follow focus if you ever tried that one. Not to bad for such a cheap follow focus!

Mounting it on the camera:

I placed a gear on my lens and put the followfocus on the rails. It was pretty tight putting it on- maybe the rod spacing distance on the trusmt was slightly too narrow- I tried it on another rail system and it did the same- tiny bit of work to clamp it on to the rails (I was using chrosziel matte aluminum rods, maybe it works better with steel)

It felt pretty good, but I noticed it took a lot of effort to drive the lens with the follow focus- this was probably because the gear box had too much dampaning grease in it as I was using it on a very smooth focusing lens. But it wasnt terrible- Would actually feel perfect on an AF lens as they seem to have near zero dampening or feel to them in the focus ring.

Hard Stops:

This just got in the way for me so I removed the blue disk along with them using the included tools, they just kinda flopped around or if I locked them, wouldnt allow full lens rotation- you may like them on

Alternate opinion:
My friend who mostly produces but shoots some too came and checked out the rig- and after feeling the follow focus said he thought it felt amazing "So much better than my (XXXXXXX more expensive) follow focus I have" (im not going to name names)

4 Weeks later, pros and cons:

Pros:

Looks nice

Really great build for the price, I dont think you can get anything better here at this level

Versatile mounting from the articulating arm

Good "feel" to value ratio (no arri or chrosziel, but for follow focuses under $900- this thing competes well at its price point)

Comes with extra tools/parts

beveled magnetic marking disk

Drive gear can be moved front to back with one screw

Did I mention this is a nice working follow focus for $399!?!

Cons:

Gear Box is too well dampened (not good for cine lenses, but again I dont think its aimed here- its aimed at people using AF lenses)

Hardstops are OK but better to take them off unless you have an extremely short throw AF lens (just remove 2 screws on the handwheel, then 4 screws to remove the blue disk- put the hand wheel back on)

Some play (About 2 mm isnt bad, but I would prefer zero play- but then again who wouldnt!)

A bit heavy

Some torque in the Arm part if you have it up too high, could be beefed up here a bit

Conclusion:

Let me get real- This thing is no Arri MFF-1, its 1/4 of the price- what did you expect? With that said, I do think its more than 1/2 as good the the Arri, which is saying something. Is it going to be my follow focus on my f3? On a red? maybe not, I probably will have to go to Arri for that.

Will trusmt provide good customer support? I dont know

Is every unit made well? I cant tell you

But for $399, I feel I have a great value of a follow focus unit- perfect for any dslr and ideal for any dslr with AF lenses: I.e. The gh2.

If you have a dslr and your looking for something nice looking, well built, that will actually work as a follow focus and you only have $399 and you appreciate taking a bit of risk- I can honestly say this is the best cheapest follow focus ive tried and would recommend it. Hopefully Trusmt will continue to improve on the design and make it even better in the future.

(Disclaimer: I dont know trusmt people so I cant vouch for them, nor have I received any compensation- Im just basing this review and recomendation off of this one follow focus model I bought from them on ebay, do your own dilagence and get other opinions too!)

Some camera porn attached (again, not ideal for an f3, just showing you!):

Does GH2 go to sleep when no displays are in use?

jimtreats — Thu, 04 Aug 2011 20:01:00 +0000

When i was shooting a wedding a few weeks ago I ran out of battery power, having only had the 1 battery. I've now brought an official spare one so hope to be good to go for at least a days worth of casual shooting. During the wedding there were times where i left the camera switched on, the monitor was folded away and the EVF was off as it wasn't to my eye. I just wondered at the time, and more so now whether in this sort of configuration the GH2 may go to a lower power mode to save battery life, ie. is the sensor perhaps powered down etc.

Hard to know, to my knowledge the manual doesn't mention anything of the sort. It'd be a nice thing to have though, one step closer to that walk around all day with a dSLR switched on and no significant battery drain. But then again with their pentaprisms SLRs have it easy in this regard.

Cheers

One area is darker on footage.

Gabel — Tue, 26 Jul 2011 15:51:58 +0000

Hi! I have a European GH2 that I've applied the hack to (high bitrate AVCHD, GOP 3, 30 minute limit fix and NTSC/PAL switch). So far it's been working great, the little I've tried it.
But a friend of mine borrowed it to shoot some stuff and said that he got this weird line over the right part of the frame. The footage he had didn't show it (but they had emptied the cards), but I shot some time-lapes today that showed the same line! The odd part was that I had one short clip that was overexposed, that didn't show this line, but all the other ones did. I did use an ND filter on these shots, but it is not on the filter itself (as some clips didn't show it). Does anybody know what could be causing this?

Dream World

Vitaliy_Kiselev — Mon, 20 Jun 2011 13:00:34 +0000

Free running with the Panasonic GH2 – Frank Sauer shoots the fast moving sport using autofocus

Short documentary Dream World is about Jason Paul, a free runner who tries to find new ways in his daily life to fulfil his inner needs. On his journey to London he discovers that friendship and companionship are essential values in life.

Jason Paul is an outstanding free running athlete and a good friend of mine. When he asked me to join him at the Red Bull Art of Motion event in London I was more than willing to break out of my daily routine as an animator and director. Free running is still a very young sport. An event like the Red Bull Art of Motion gives athletes from all over the world the possibility to meet, train and communicate in real life, instead of checking each other’s videos on Facebook.

On this particular trip my personal dream was to have a great time with all the athletes, while having the possibility to shoot my short documentary. From the beginning on I wanted to make a film about free running that is not based on difficult tricks or risky jumps, but on interesting characters and the philosophy that comes with it. We started our journey in Frankfurt, Germany, where we went to isolated run-down houses as well as crowded pedestrian areas. I myself had to climb quite a few times to get the shots I wanted or just to follow the guys on their run. I tend to let things happen or just let people do their thing, hoping to discover something within the moment.

All the equipment – including the light weight Panasonic GH2, GoPro HD, Panasonic 20mm, Panasonic 14-140mm, Panasonic 7-14mm, Zoom H4n, Rode VideoMic Pro, Joby Gorillapod and a small rig – fitted in one backpack and made it possible to follow the guys.

Gorilla Plate for GH2

Tommyboy — Wed, 03 Aug 2011 11:50:49 +0000

I'm looking for suggestions or "zacuto" gorilla plate for gh2. My setup consists of dslr base with D|focus follow focus system and zacuto gorilla plate. I found this setup to work perfectly on the canon cameras however, the zacuto gorilla plate is too big for my GH2 and there is no way to replace the battery with the gorilla plate screwed to the camera . The reason why I need "zacuto" gorilla plate for my gh2 is that is more portable and easier to slide up the camera from the dslr base with out touching the follow focus system. Any advice?

GH2 Rocks the House - Awesome Looking Commercial

Its currently being transferred to film and shown in the local movie theatre, where the film festival will take place.

Panasonic GH 2 LCD Monitor flickering

Retina — Thu, 28 Jul 2011 14:59:35 +0000

I've been trying out my new Pana GH 2, and I'm wondering if what I'm experiencing is normal for the GH 2, or if it's defective... When I'm shooting, the LCD monitor often seems to black out/flicker. This doesn't seem to happen when I'm playing back, or in photo mode (not sure about that last one).

Is this normal behaviour, and if so, how can I prevent it? Or should I send it back to the store? :-(

Video Plays Fine on Camera but Constant Blips on Computer

surfr1121 — Mon, 25 Jul 2011 19:44:31 +0000

Hey everyone,

I just installed the hack the other day and everything I have shot so far has been fine with the exception of the first couple of seconds of every video having the "blip," but today it figures when I go to shoot something important the video looks fine on the camera but when I do a log and transfer in FCP7, the video has constant choppiness and "blips" all over the place. It is now completely unusable. I thought that the problem might be log and transfer but then I tried to convert it with Toast Titanium and had even stranger results. The .mts file is almost 600mb but when I drag it into Toast, it says it's 2mb and when I export it, it just exports a 1 second clip of just solid green...?? What the heck!? There must be some way to save my video! I mean if it looks good on the camera playback then the file must not be the problem right? Someone PLEASE help me out here!! I was using recommended settings of 42000000 in 24H mode if that helps...

Thanks for any input

What is going on with the "blip"

cbrandin — Mon, 25 Jul 2011 12:01:36 +0000

I have been doing a deep dive into the GH2 quantization process. While investigating that I think I figured out what the "blip" that happens in the beginning of streams is. First of all, it happens with an unhacked GH2 as well - it's just not as visible. When a stream starts the codec starts with default quantization values - which are never optimal. As the first GOP progresses the codec is making adjustments to optimize the quantization process. Of course, not much optimization happens in the first GOP because the first I frame (which is used as a reference for the following P and B frames) is not very good. By the time the second I frame has passed things are much better, but still not optimal. By the time the third I frame passes things are better still. From my measurements things are typically optimal by the 34th (in 24H mode) frame. The 34th frame uses the 36th frame (the third I frame) as a reference, so that makes sense.

At the beginning quantization values for frames vary widely, from a minimum (best quality) of 18 up to 51 (worst quality). By the time the 34th frame has passed the codec settles into a pattern where all P and B frames use a quantization value of around 20 (an entire P or B frame uses a single quantization value). I frames typically use a range of 5 quantization values; it is usually in the range of 18-22. The absolute values can vary one or two values, but the pattern is consistent. For example, for highly detailed scenes I frames range from 18-22 and P and B frames are at 20. For lower detailed scenes those values may go to 19-23 for I frames and 21 or 22 for P and B frames.

Dark scenes seem to cause the quantization values to be low. Currently, the lowest quantization value I've seen is 18 in I frames and 20 in P and B frames. This is true with both hacked and unhacked cameras. Currently, Vitaliy and I are working on trying to lower that. It's not as simple as we had hoped so it may take a while.

The conclusion I have come to is that it might not be possible to eliminate the "blip" because that is when the codec in configuring itself. Note that the blip exists in an unhacked GH2 as well, though not as visible. I think Panasonic made the choice to at least record something, even though the codec isn't really ready yet. I think it was a good decision.

I need to tilt down from the blue sky to the sea surface. I know that the sky and sea can create havoc for codecs. Any tips for settings? ISO 160, I do have some ND filters, what other settings might mitigate some of the artifacts and anomalies that might come up?

GH2 firmware re-write limit?

bwhitz — Wed, 20 Jul 2011 21:31:37 +0000

Don't know if this has been covered anywhere, but I haven't seen it yet...

Is there a limit with the amount of "re-flashes" you can do with the firmware? Will it lose reliability at any point like a SD card?

GH2 in stock at Panasonic Direct via facebook

GH2 AVCHD Encoder Motion Testing

cbrandin — Tue, 19 Jul 2011 13:46:16 +0000

There is a lot of static testing going on. I wonder, though, whether the real advantage of higher bitrates manifests itself in dynamic scenes more than static ones. Therefore, it seems logical to set up some sort of standardized test for resolution vs. movement. Something like shooting a resolution chart while panning slowly (at a fixed rate) might show whether there is improvement in dynamic scenes.

Shutter speed will be an important consideration, as the slower it is the more blurring (and the less detail) there will be. At fast shutter speeds minute detail will change considerably between frames.

With a static scene I frames dominate, and B and P frames don't play much of a role so quality improvements concerning those won't show up.

I'm going to play with this a bit. In the meantime - any thoughts?

Chris

Plans: PTools settings as GH2 menu items?

EOSHD — Wed, 20 Jul 2011 09:23:37 +0000

I remember Vitaliy said that execution of the firmware happens in RAM on the GH2, so that firmware could be manipulated via the camera menus whilst the GH2 is running. Is this plausible to implement, anything promising in the code so far Vitaliy?

I'd love to see such a feature, it would make testing much faster and avoid need to keep updating with a new firmware when settings are changed.

Does hacking with ptool permanently alter my GH2?

jimtreats — Mon, 18 Jul 2011 16:51:58 +0000

Hi.

I know that the first post of the main topic is linked to to describe how to actually apply the ptool patch to your GH2 camera. But the one thing I can't quite figure out is whether the current hacking permanently alters our cameras or does it only apply the patch whenever we boot the camera with the file on the SDCARD. I'm used to hacking my 550d in which the camera boots into the hacked firmware whenever the hack is on the SDCARD. This is good as you can always get back to the stock camera, but a bit of a pain as you have to ensure the hack is present on all cards, and you can not format this card without reapplying the firmware hack files to it.

So does ptool hack the camera permanently? If so can we revert to stock firmware?

Finally, I'm sure I saw some mention of a mac version of ptool before the hack for the GH2 was released, now i see that the windows version is recommended to be used instead, is the mac version just not an option right now?

Cheers, I'm just excited to try the hack at some point in the near future but I would just like to know exactly what i'm doing before i contemplate doing so.

Awesome work, and I really start to like this forum for all the other informative posts, not just the incredible hacking progress.

Cinema 24p, best manual settings ?

feha — Fri, 15 Jul 2011 20:57:31 +0000

I wonder does anyone else have similar problems with Cinema 24p mode manual settings ?
GH2 - pal version
Lens: 20mm 1.7 "pancake"
I tried:
Cinema 24p
Exposure M
aperture: 1.7
shutter speed: 1/50
iso: 160

if I don't pan camera it is all OK, but if I pan i get jerky (similar to fast motion experience,about 10% faster at least in my LCD monitor ...).
i get same on any exposure mode when using Cinema 24p

but in Creative Movie Mode I do not have these problems when using exposure in P mode ...

Any tips ?

PTool 3.60D: Encoder Setting 1 controls B-Frames

mpgxsvcd — Thu, 07 Jul 2011 23:30:41 +0000

I have isolated Encoder Setting 1 for 720p and I can unequivocally say that it determines whether the codec uses B frames or not. If you change nothing else and use Encoder Setting 1 = 3 it will use B-Frames. If you use 2 it will not use B-Frames. It also increases the bit rate up to 22 mb/sec to almost 24 mb/sec. Using B-Frames with 720p improves it tremendously. However, stability is an issue. If you record a 1080p @ 24 FPS video first and then record 720p @ 60 FPS stability returns.

I have attached the testing I have done so far and the best stream parser results I have seen. VLC indicates that this is still true 720p @ 60 FPS with B-Frames.

Feel free to use this information as you see fit. I don't need credit. It is not like I am planning on getting a patent on the settings or anything.

Great time to own GH1 and GH2

stoney — Fri, 08 Jul 2011 10:30:35 +0000

It seems GH23 (???) testing is making fast progress. Much faster than GH13 when it first came out. Woo hoo!!!!

GH23 as A cam and GH17 as B cam.

Use GH17 for time-lapse. Prolong lifespan of precious GH2 sensor :)

We don't discuss often, but GH2 is a very nice photo camera, too.

GH2 Speculations

CRFilms — Thu, 07 Jul 2011 04:39:50 +0000

Anybody remember off hand how long the original GH1 hack was working until Panasonic changed the firmware? Chances are they'll make the new hack unhackable in time.

I have no money coming in cause I'm off work for the summer(school job) so I'd like an idea if I need to get a part time job so I can get one ASAP or if I can wait 3-4 months and slowly save up.

GH2 cuts last few millisecond footage

flyguy — Thu, 09 Jun 2011 08:53:57 +0000

I have a problem with the last few millisecond of my footage recorded on GH2. It seems after i press stop record, it will delay for say 1-2sec for the video to be written to the card and etc. After that, when i played the video, the last few milliseconds is missing. Is this normal? How can you fix this? I've tried with every setting but nothing seemed to work. I am using a Class 10 SDCard so i dont think thats the problem. Anyone experience the same issue? Thanks
