GH2 official discussion thread

At the risk of stating the obvious, and assuming the HDMI signal fully-tracks the camera setting profile, I'm guessing the problem goes away with an external recorder.

Yes and along with this your $1200 (Ninja+cheap SSD).
Most people here will never buy external recorder. :-)

I guess then it's the rest of us not at DVXUser who are salivating at the thought of using the only DSLR that may work with a NanoFlash, Ninja or KiPro Mini. (Not to mention those manufacturers looking at a whole new market.) For us, 24 Mb/s & DSLR audio does not cut it. But the image & price sure does. As for clean HDMI out, I think Philip Bloom eloquently says it all if I may quote: "We all want it so please please please please please pleaseplease please pleaseplease please pleaseplease please pleaseplease please please PLEASE add it!"

That's certainly an option, when it is confirmed that HDMI signal in 760 mode is indeed 50/60 fps progressive (I haven't yet seen a confirmation of frame rates, just that the signal is clean of nags and overlays). As Vitaliy said, there is [considerable] cost involved with this option however. More importantly [for me], it is another gadget that needs to be attached, powered, connected and checked to make sure it is functioning that slows you down. I would much rather prefer the camera to already encode a "decent" footage, which a GH13 does for me. So everyone's situation is different, but it's great that one has options now.

The $1000 Atmos Ninja records only to ProRes, which doesn't really suit my Win7 CS5 workstation. The only other external recorder that's small enough to mate comfortably with the GH2 is the Convergent NanoFlash, which is nearly $3000. That plus the GH2 would cost nearly as much as a Panasonic AF100.You can probably guess which option I'd go for...

I may be wrong, but was under the impression that ProRes worked fine with both CS4 and CS5 on a PC as long as you have QuickTime installed. There apparently is also a dedicated ProRes decoder for Windows http://support.apple.com/kb/DL2
 
2 questions about the tele conversion feature:
1. I've seen some discussion about this, but haven't seen an answer- has anyone found a fast c-mount zoom lens, with the wide end 28mm equivalent for 35mm or wider, that would work with the tele conversion of 2.6x with no vignetting? Something like a 6-48mm f1.8? In other words, roughly equivalent to the 14-140 kit zoom in coverage, but much faster? Doesn't have to go very far on the telephoto end to suit my needs...
2. Does anyone know if the teleconversion switch can be applied during a video shot, with no delay or brief blackout or pause in the video? I do a lot of wedding work and this would be a great way to simulate having two cameras. You know, like switching back and forth between different cameras at a live event.
 
I would like to know if it is possible to shoot video in 4:3 aspect ratio with the Panasonic GH2, as I would need 4:3 25p video for shooting news for a regional broadcaster.

Shoot 1080i, deinterlace, and crop to 4:3. That is about your only choice with GH2 unless you want to shoot MJPEG and crop or VGA. That might be acceptable for news though. My local TV station(WRAL) was one of the first to go HD back in the 90's. However, their live coverage from the field still looks worse than the old SD 480i stuff. Their 1080i studio shots are some of the best in the business though.

The 14mm F2.5 pancake is ideal for the teleconversion feature. After 50mm equivalent you are going to need image stabilization for hand held video. You can't adjust the teleconversion feature while filming because it would have to adjust resolution from 1080 to 720p during filming. That just doesn't work.
 
I think it will shoot 640x480 MJPEG @ 25 FPS 4:3. That is probably his best option for conformance. 720p is his best option for quality unless you subscribe to the "1080i/60 = 1080p/30p" theory.

When using fast c-mount zooms, forget about wide angle. Even at 9mm angle, 9 * 2.6 * 1.8 = 42mm equivalent in 35mm format. You'd need a fast c-mount zoom that has 6mm to cover 28mm equivalent, and it better be sharp at 6mm. Good luck.

You in Raleigh? That's the same station as my local news :)

Yes the 14mm would be great, but I'm talking about zoom. For example, I see there is a Tokina 6-15mm f1.4 c-mount for 1/2 sensor. With 2.6 teleconversion this would be around 32mm-78mm 35mm equivalent, almost what I want at the wide end although I'd like more tele, and extremely fast. Would that vignette at the 2.6 teleconversion (1080i)?
And I'm not talking about switching the teleconversion from 1080 to 720. I'm talking about having the feature turned off while shooting video, and then turning it on during the shot. As with using the 14mm for my wide shot at 28mm 35mm equiv., and then instantly cutting to the roughly 75mm equiv. mild telephoto shot by simply turning on the teleconversion.

So you're saying that something like the Tokina 6-15mm is unlikley to be sharp enough at the wide end?
