GH2 Sleeps while I'm shooting a time Lapse.

jvalal — Fri, 16 Nov 2012 19:31:10 +0000

My Hacked GH2 sleeps while I'm shooting a time lapse video. Is there a way to disable the "sleep" function so I can get a full time lapse?

Motion time lapse vid with GH2

ed_lee83 — Wed, 14 Nov 2012 21:09:17 +0000

Hello all! Wanted to share this time lapse video I shot exclusively on the GH2 in my home town of Hong Kong. It's become my spare camera after one year of heavy usage, but it's still alive and kicking! Mainly shot on 14-42mm lens with circular polarizer. Powered with a generic DC coupler + Sony F battery adapter.

GH2 vs GH3 HDMI Monitor Output?

willianaleman — Wed, 14 Nov 2012 10:01:00 +0000

The only feature that would make me jump and upgrade from GH2 to GH3 is the limitation in the GH2 of output monitoring though the HDMI to an external monitor. When using an external monitor during recording, spanning gets interrupted no matter what spanning patch is being used. The GH2 just stops recording.

Accordingly to the last response I got from V. Kiselev in this forum was that it hasn't been fixed. Then, accurate focus is the biggest issue I have been encountering with the GH2, specially for run and gun type of shooting. I'm hoping that the GH3 doesn't have this issue.

Video Info Software

producer — Fri, 19 Oct 2012 13:09:58 +0000

Does anybody know a software which gives complete info about a video file?

What I mean is like MediaInfo, but what I need is full information of GH1/2 video file: Shutter, WB, ISO, etc.

GH2. What is best, Black & White in post or in camera ?

Hello. The title says it all. Is there any theoretical reason for a difference in quality ?

AVCHD 1080p time lapse

balazer — Sat, 26 Nov 2011 04:10:11 +0000

You can shoot video in any mode and use software post-processing to apply any speed-up that you want. I shoot with a wide shutter angle and use frame blending to make the motion look smooth. This simulates severe undercranking with a 360-degree shutter.

This particular example was shot on a hacked GH2 in AVCHD 1080p 24-fps mode with the shutter speed set to 1/2 s. That makes the recorded video have 13 frames for each picture taken, for an effective frame rate of 23.976/13, or about 1.84 fps. You can set the GOP length to 13 frames, which will give you one I-frame for each picture taken, and then use just the I-frames in decoding. That increases compression efficiency and gives you longer recording times. The shutter angle here is 332 degrees, or 92%, which isn't bad, but ideally you want to get closer to 360 degrees so that you don't have discontinuities in the motion trails. If I did this again, I would have shot 8-fps in 300% variable mode with a 1/8 s shutter speed. Using a lower frame rate of course means there is less video data that needs to be processed.

Here's the video data flow:
camera MTS -> Haali Media Splitter -> ffdshow tryouts decoder -> Avisynth -> makeAVIS -> Sony Vegas

Here's my Avisynth script for doing 65x speed-up: 16.25x from undercranking and 4x from frame blending:
DirectshowSource("input.MTS")
SelectEvery(13)
c1=selectevery(last, 4, 0)
c2=selectevery(last, 4, 1)
c3=selectevery(last, 4, 2)
c4=selectevery(last, 4, 3)
blend1 = Overlay(c1, c2, mode="blend", opacity=0.5)
blend2 = overlay(c3, c4, mode="blend", opacity=0.5)
Overlay(blend1, blend2, mode="blend", opacity=0.5)
AssumeFPS("ntsc_video")

Time lapse photography has practical applications. Say you are filming a car driving by at 10 miles per hour, but you want to make it look like it's going 60 miles per hour. If your target format is 24 fps with a 180-degree shutter, you can shoot 24-fps with a 1/25 s shutter, and then blend the first three frames of every six into one output frame. Or you can shoot 8-fps in 300% variable mode with a 1/8 s shutter, and drop every other frame. If the car is going straight down a road with no bumps or curves, the effect will be totally convincing. :)

GH2 Made in...China, Japan, etc...

fosterchen — Fri, 05 Oct 2012 14:10:33 +0000

Just curious as to all the different places of manufacture for the GH2. My GH2 says made in China, and I bought it from B&H when it was $599 back in March/April 2012 for only a day. (Wonder if that's the reason it was much cheaper) It's been working fine and hacks work fine too.

I've heard of earlier GH2's made in Japan, but wanted to confirm and see where everyone's GH2's were made and when they bought it.

Thanks!

A Prewedding Film | A Pretty Cool Way To Keep A Memory

pchristoph — Fri, 09 Nov 2012 23:26:19 +0000

We make the occasional pre-wedding film for engaged couples who want to share a bit more of their story and personalities with their wedding guests. Usually a film like this will get played at the wedding of a reception on a big screen before the happy couple is announced and they walk into the room. When we screened the film with them they got really excited and wanted to post in online right away. So here it is. It was shot primarily with Pentax takumar glass and the 12mm from slr magic. While I like the 12mm wide angle it is a harder lens to cut in because it is higher contrast...I still like the less sharp/cinematic feel better than the Oly 12mm though. Glidecam shots on a 50mm macro tak. Some good fun and shot in about 4 hours over four locations on a cold clear October day. The gh2 cameras are brilliant for activating ones creativity in real time. I could never have been able to setup so quickly for shots, nor risk the variety of camera angles on the shotlist from rolling from a larger camera system over such a short period of time. I just gotta learn to color grade better. Anyways, cheers and good hunting all you creatives.

gh2+14-140mm : focusing points in advance...

magnifico — Mon, 05 Nov 2012 13:04:20 +0000

I just want to keep in memory (marking with some tape my 14-140mm) to points where to focus. The problem is that gh2 and 14-140 just loose "memory" : that means even in manual focus mode, when I move the focus ring and I am back to the mark I did, the image is not focused any more ! 14-140 mm is given as a video lens : how can I prepare in advance some points to focus and go from one to another while recording (in manual focus mode) ?

Fixing a Damaged Disk Image from SD Card

willianaleman — Fri, 09 Nov 2012 14:20:23 +0000

In the Mac OS operating system, I have a disk image created from a SandDisk SD card, with a 9 GB GH2 footage content. The disk image can not be opened. The operating system displays the following warning when attempting to open it: "The disk image you are opening may be damaged and could damage your system. No mountable file systems. Are you sure you want to open this disk image?" The options are, Open, Don't open. Of course I haven't opened it.

This is the first time this happened to me. I have tried Disk Utility to fix it without success. Has someone had a similar experience or have a recommended application to fix the disk image?

Thanks in advance!

I believe know why Coppola chose the GH2 at Zacuto Revenge Shootout 2012

Manu4Vendetta — Wed, 07 Nov 2012 22:33:23 +0000

I watch some movies I subtracted master Coppola, including an excellent thriller 'The Conversation' of his early years. My first reaction just came out the first pictures is that it looks like when you combine the GH2 or GH1 with old lenses for its look and color, but the texture of the film different though but not as radical.

I think what Coppola to see shots of the GH2 was somewhat familiar with this movie great unknown but which he felt so proud. I'd love to ask him about it, but that is almost impossible.

Excuse me if this thread its trivial and offtopic, but wanted to share this impression.

And I recommend to all screenwriters and directors see this movie frugal, sometimes with limited resources and without a very complex story, but well told and surprising elements can do a good job in this case is a masterpiece.

Attached some pictures of it.

PS: Sorry for my poor English.

GH2 + 35-100mm + GoPro 3 Black does BMX Freestyle

mpgxsvcd — Tue, 06 Nov 2012 11:11:23 +0000

Here is a set of highlights from a local BMX competition that I filmed with my GH2 + 35-100mm F2.8 @ F2.8 and my new GoPro 3 Black mounted to the hot shoe. The clicking noise in some of the clips is the GH2 taking stills while the GoPro Recorded video.

I know the editing is poor in this video. I shot WAY TOO MANY things this weekend and just didn't have time to do the editing justice. Take it for what it is. Just a bunch of samples from both cameras.

I tried editing the colors on the first few clips but after that I just didn't have time. I shot in 720p 60 FPS and F2.8 for the GH2 shots(Can you tell which one those are?). And I shot at 720p @ 120 FPS Narrow angle non-Protune, 720p @ 120 FPS Wide angle Pro-tune, 1080p @ 60 FPS Medium Angle Pro-tune, and 2.7K @ 30 FPS Pro-tune for the Go-Pro 3.

Can you tell which clips are what resolution and frame rates for the GoPro? Hint, several of the clips having very bad aliasing in the fence in the background. That is eliminated by using a narrower field of view.

There is also a sample image below of what the GP3 looks like on the GH2 + 35-100mm.

It's Always Sunny With.... Flowmotion Skatepark Edit

Stiffla — Tue, 06 Nov 2012 09:27:39 +0000

Hi,

we had been been filming for 2 month in Vienna and this is what came out. I used Flowmotion 2.02 in HBR mode. So far I do not regret it, nevertheless 50p would have been better for slowmotion.

Critical feedback will be much appreciated.

Voigtlander Nokton 50 (1.5), Nokton 58 or Leica Summicron R 50 on the GH2 - your "Personal View"

gameb — Sat, 03 Nov 2012 10:39:56 +0000

Don't kill me because these lenses were partly discussed in earlier topics. I don't want to discuss the sharpness or optical details of these lenses. What interests me is their character... I am a bit tired of the sterile Panasonic look, even if I love my 20mm Pancake or the 14mm. But I want to change my whole line-up to a more personal aesthetic, including the wideangle, normal and tele range. I would like to try them all out and see which one I like, but this is impossible for me. This is why I am asking you your "Personal View" about them (lenses mentioned in the title are more or less in the same price category). May be some video samples?

Value of gh2 in relation to gh3

hay — Fri, 02 Nov 2012 23:44:58 +0000

i could use some input re: the soon to be discontinued gh2.

my projects are displayed on 60 inch+ lcd panels and digital projectors. i've used, extensive in the past, a borrowed gh2 and have been impressed with the hacks over the stock firmware. considerations: - i don't plan to use in-camera audio recording, - DR isn't as important as image sharpness and pixel structure, - i have enjoyed using the high bit rate hacks in the past, particularly the v9b and i do a fair amount of grading in post

also, any idea how the 100mbps+ hacks impact the life of the camera? i recall reading something by a panasonic engineer who thought the hack "overload" would diminish the lifecycle. any real world examples of this?

thanks for the help.

Longboarding

La Salle de Classe - GH2 + Dolly Test (Driftwood)

brettplank — Wed, 31 Oct 2012 15:19:48 +0000

I managed to use my school's dolly to pull off some test shots for smooth camera movements. Take note that I used and controlled everything singularly: I pulled focus, performed pans, and physically pushed the dolly itself. It was difficult, but I managed to get some usable footage. With one or two extra grips I can easily pull off great looking, smooth shots. I'll be shooting more with the dolly this week. I like grain.

A cautionary tale (about hacking and memory cards)

TommiH — Sun, 19 Feb 2012 15:01:51 +0000

I had the opportunity to fly a DC9 simulator with my father (i'm sitting on the left, my father sitting on the right seat in the video). Planned on recording every second of this once-in-a-lifetime deal (that's why i'm wearing the GoPRO). And what did I forget to check? The memory capacity.. "V1"..[END]. THAT'S WHY you always make sure, you have large enough memory card in the camera! :D -- Card Full, 3 seconds before rotate... In a (soon to be extinct) DC9 simulator. Now that sucks. Shot with a 44 Mbit setting on a hacked GH2

Broadcast quality issues with the GH2 in Europe

gameb — Mon, 29 Oct 2012 15:57:11 +0000

Anybody heard of broadcast quality issues lately shooting with the GH2 for national TV stations, like german TV, british or french? Somebody told me, they won't accept documentaries shot with the GH2 any more, is that true?

How do i reset my GH2 back to the original state?

Hacked GH2 - No Spanning, multiple copies of the same file instead.

MetaControl — Sun, 28 Oct 2012 03:44:50 +0000

I just got the GH2 and tried some hacks, but they do not seem to work for me.

I tried Flow Motion 2 and some Driftwood series 6 settings, but I had the same problem with both of them. I did not go into quality tests yet, because I wanted to check workflow options first, with different fps settings in Flow Motion 2, without success, but also found out that spanning did not work with it and I wanted to get that right first. After some tests I found something strange happened. Instead of a range of MTS files spanning, I now get several files with the same content. The longer the clip gets, the more files there are, which makes me believe it creates a new copy of the original file every time it is supposed to span into a new clip due to the 4GB limitation. The files do have subtle differences in size, but are all around 4gigs, but I think it is only the variable bit rate. Here is some stream info example on 3 (of five) duplicate files.

Even the clip duration seems vary, but inside premiere they are all the same length. Usually only one of the files retains any sound. I am deeply confused to what is happening, and would appreciate any insight any one might have. I will try some more settings and probably go back to stock too, just to check whether it happens there too.

One thing to note is the card I am using. I read some controversial and mostly unclear posts one which cards work or do not. I have been using a 64GB SanDisk Extreme the SDXC1 U1 Class 10 with 45MB/s. Even if, what some of the posts say, it would be only half as fast, it should still be able to keep up with the bps the tried settings use. The only other card I have to test at the moment is a 32GB Transcend Class 10, but that has only 10MB/s and is used usually for photography only. I am about to order the 64GB Extreme Pro 90MB/s but I still think the one I haver should be fine. I am not using the highest bit rates anyway...

Thanks for any knowledge you can share

GH2 Flow Motion SH Hack Issue

tderuiter — Fri, 05 Oct 2012 19:00:56 +0000

Hey guys,

I just recently bought a 64GB Sandisk Extreme Pro Card (With 95mb/s) and I applied the Flow Motion v2 hack and tried the Driftwood Apocalypse hack and 720p at 60fps doesn't work. It cancels the recording and says the write speed of my card isn't fast enough. I don't understand why it won't work. The card is the top SD card for the GH2.
