Live recording off of HDMI?
Has anyone tested this yet? Does the GH1 send a live signal out the HDMI port when shooting, or not? It seems like not having a mirror, there should be no fundamental reason why it couldn't. (Except of course, that Panasonic doesn't want to cannibalize its camcorder line!)
If it sends uncompressed out the HDMI pipe, then you could add a nanoFlash, avoid all the AVCHD issues, and REALLY give Scarlet a run for its money. It'd probably be cheaper, too, when all is said and done. Does anyone have a GH1, a HDMI cable and an HDTV who could test this out? |
I believe a few people who have the GH1 have tried this and so far have had no success...so far..
|
The GH1 does not do video-out of any kind, neither composite nor HDMI, while recording video. Why would a mirror box have anything to do with video-out capability? Please explain your thinking...
The GH1 doesn't do HDMI video-out while recording for presumably the same reason why the 5D Mark II doesn't do HD video-out while recording: The processor might not be powerful enough to simultaneously compress the video and send a full-resolution copy out of the HDMI port. Of course, the camera's positioning as a consumer product also likely has something to do with it. |

2. A number of consumer cameras support Live HDMI out. The Sony HCx series does and I believe the Canon HFxx series and HFSxx series cameras do as well. I would also point out most, if not all, of those cameras are considerably below the GH1s price point. In a camera at the GH1 price point, with video being a major reason for its existence, the lack of live HDMI out, the 17 Mbps codec limit, and the lack of B-frames all point to Panasonic imposing some hard limits between their consumer and professional camera line. Specifically, with a Live HDMI out port, you can consider the following: 1. Sony PCM-D50 for audio. That's what I have. Substitute your favorite as you see fit. 2. NanoFlash or Matrox MXO2 Mini for a high quality codec/recording options. For the GH1+PCM_D50+MXO2 Mini combination, paying MSRP of ~$2400 USD, you now have a real threat to cameras costing quite a bit more. And Panasonic knows it. I believe the real answer for Panasonic is to roll out new professional video cameras built around the u4/3rds lens mount+sensor combination, rather than imposing artifical limits on the GH1. It would allow the consumer line to bask in the glory of their professional cameras, with the professional line differentiated by pro features and ergonomics. But of course that all takes time. |
I think building a video camcorder line based on the Micro-four-thirds standard would indeed be a welcome addition -- as long as Panasonic also gives up on their outdated and overpriced P2 technology, and have it record to standard SD or compact flash media.

1) These still cameras have to go through an additional step of down-sampling the full-resolution output from the sensor to HD resolution. This is evidently a rather processor-intensive task, since all three cameras appear to skip lines in order to accomplish it, rather than perform linear or geometric down-scaling. 2) These cameras were never designed to "bypass the codec engine," and nobody ever expected them to do so. We were all hoping that we would have live monitoring while the cameras record to the flash memory. I'm fully aware of the possibilities of live HDMI recording, and I was looking forward to harnessing them myself, before the limitations were revealed to everyone. Those consumer camcorders are not really "considerably below the GH1's price point" because the GH1's current MSRP includes the very valuable ($800 MSRP) kit lens. It's an apples-to-oranges comparison. Quote:
17 Mbps AVCHD is commonplace in the consumer world, so the company doesn't bother with maximizing the bitrate to the AVCHD specification of 24 Mbps. 24p native encoding is better than wrapping the stream in 60i, but Panasonic knows that most consumers want to record 1080p because it sounds fancier, and they also want to play their videos back on their TVs, which is why the 1080p mode alone uses the pulldown encoding. The lack of live HDMI output is probably another feature that Panasonic didn't bother to implement because it didn't think that consumers would care. The complaints that people have here and at other such forums, seem to have to do with the fact that the company didn't cater its product to us. Complaining is all right, especially if it helps to create better products in the future, but we shouldn't blame the company for its choices. We are not its primary user base. In fact, none of us would even care about the camera very much if it didn't have a video mode. Quote:
The camera companies did not set out to create a filmmaking revolution like RED has done. It's just that their products are seen as revolutionary in OUR eyes. We are a small, niche segment of the market. Outside of our world, nobody sees these products or cares about them as much as we do. Average people and amateur photographers are happy with their limited consumer-grade products, which have been designed to be simple and easy to use. Professionals look down upon these cameras, or are otherwise skeptical of them, because they are used to higher standards in every aspect of the equipment (be it codecs, physical recording media, interfaces and connections, form factor, etc.). Some professionals are only starting to pay attention and show interest because members from our world are making such a big fuss about these cameras. Quote:

The whole "broadcast" vs "prosumer" division is shallower everyday (as DOF ;-)) thanks to technology running always faster and cheaper.
So Sony, Panasonic and JVC, used to sell pro camcorders in the XX.000s are not happy to see them replaced by camcorders in the X.000s. Canon who is the only one of the bigs who never had a "broadcast" department should be the one to lead the way. It never happened. So we all have to deeply thank the RED team that shaked the moving-picture market from the foundation first with vapourware, then with beta-ware. I hope they really become a more mainstream, with excellent products in stock and with the merit of being the company who brought 4K to the masses! ;-) |

Well Canon has had a broadcast division for many years-http://www.canon.com/bctv/. A significant number of broadcast cameras use broadcast lenses by Canon. Remember that Sony's TRV 900 and VX1000 and later the PD150 along with the Canon XL1 were responsible for the beginning of the affordable digital revolution. The day to day needs of broadcast television will still be met by Panasonic and Sony with higher priced,rugged and field worthy EFP and ENG gear as well as studio systems. The real threat is to Arri and Mitchel and the other film gear companies. The Sony 900 series, Panasonic Varicam, Thompson Viper and to a much lesser degree the Red One and others are cutting into their market. It is highly unlikely that you will be watching the News or an episode of Oprah shot with a Red. More likely she will be seen wearing Oakley Shades. As for Red, I for one am fed up with all the praise this company gets based on what they deliver or should I say don't deliver, the elitism that surrounds the camera and that they have set an industry standard for high def in the future. With what CG renders? Nonsense! let them put something new on the market that people can work with and buy without being on "Jim's A list" and let them meet a deadline or at least come close. I don't find the arrogant " We reserve the right to lead you on and you will not complain" acceptable. They are still selling the same camera, the Red One and the "new version" "Epic" has been "coming" for quite some time.The name is well deserved. The famous Scarlet has been "re-thought" several times and the latest version is a CNC machined block of aluminum. Jannard is a great marketer/Pied Piper and has managed to garner quite a following. I am not among them. Brian |

However, I'm not sure any of manufacturers get it, based on what they've put out lately. JVC and Panasonic continue to release 1/3" CCD cameras. Hopefully Sony has released it's last HDV camera. It could be a lag in development time, but it seems like somebody in some company would be letting on that they're developing large, single sensor CMOS camcorders. Canon doesn't release products that often from their prosumer video division. I think that they're hoping to get a couple more years out of their HDV product line. Dropping sales could make them rethink that, but if they wait too long they'll get passed up. They also don't have a good codec solution like Sony does with the XDCAM EX (I think that the 5D codec is actually pretty bad). I'm still optimistic, but skeptical as to how fast this is going to happen. I think it could still be 2 years away. Unfortunately, I need to replace my V1 before that. |
Sorry for the off-topic, but yes, live usable HDMI output is not done to try to save some broadcast market alive...
I agree with Brett too, prosumer gear nowadays is more pro than sumer... ;-DD |
I think that we all agree that the quality of the gear available under $10k is amazing these days.The GH1 is an amazing example of this, and I can't wait to use it and like all here wish it had this or that but the fact is it is a camera that costs less than two grand. People spend more for matte boxes.
I think it is professional gear, I am a pro like many of you and I will use it along with the other cameras in my kit. I don't think you need to subtract anything from it. It is what it is and leave the rest to the engineers. Disco may have to change its bogus out of date standards to catch up with the real world. BUT: If you have to work it on a daily basis and it is your personal gear and you take care of it, the chances are it will work for you for a long time. If it is gear that is worked 18 or 24 hours a day and shared on a truck between two or more shooters and then handed off to "buddy" while you are on vacation and OH Yeh! the weekend guy needs it. Well my friends you get what you pay for.... You need something robust and my dear little HMC150 or before it my DVX100B would not stand up to being passed around. So yes we can all mesaurebate about the codecs etc. But the bottom line is the designation "PRO" is also about durability and compatibility and system. Not everyone is an INDY film maker. Big companies service other markets and whether we like to admit it or not we are small time. If we were not then ABC, BBC, CNN, CBC, CTV, CBS, FOX, NBC, PBS, DW, TV GLOBO, and so on would be out of BIZ. |

2) RED's philosophy and strategy is the exact opposite of that of other camera companies. With other companies, mum's the word until the product actually drops. Take Canon, for instance. They didn't even admit to working on a manual-control update for the 5D MkII until the press release saying that the firmware would be posted a week later. What RED is offering is transparency. If other companies offered the same kind of transparency, then they would appear to be as capricious as RED does. It's really a matter of taste. You can be frustrated at the changes and the delays, or you can be frustrated at the refusal to disclose anything. Quote:

Also, for those who don't know, Panasonic Consumer doesn't have a professional video line to protect. Panasonic Broadcast is actually a separate company. There is practically no overlap between the two companies.

RED has changed the game. You don't have to buy from RED, you can buy from the competition. But you have to thank RED for the products of the competition too!!! ;-DD
Fei, Panasonic Pro and Consumer maybe two different companies, but I don't think one wants to hurt the other! |
If that was the case, than we would have at least have live output to an external source like a monitor when recording (I don’t mean uncompressed output by the way). I bet that’s more political than technical if you ask me. If you look at the 5D Mark II, certain manual features were deliberately disabled and after people been using lots of Nikon lenses and a hacked firmware was developed, Canon was forced to change their mind and announce a new firmware.
The fact of the matter is that Sony, Panasonic and Canon will most of the time try to separate the features of their other products. This is one of the reasons why a lot of people are begging Nikon to release something special because their isn’t any camcorder to protect, consumer or professional. Sony would probably have some development in the CMOS chip and that could either be a good thing or a bad thing. As for RED, I think it’ll be a while until they ever release an interchangeable lens camera that will have a price similar to the 5D Mark II. |

Or the "overpriced" P2 technology that just got slashed in price to about 1/3 of what it was? Quote:
Eh, point being: if you want commodity media recording, that's what AVCHD is for. Cheap recording on cheap media. If you want professional media, the P2 card is currently the cheapest and most adopted solid state media in the world, so don't expect to see it "outdated" any time soon. |

These companies cram in everything they can, while meeting a specific price target. Look at the HPX300 -- you don't think that's cannibalizing the HPX500 and even the HPX2000? Of course it is. But the company's attitude (as is the attitude of any company that wants to stay in business) is, if the older product can't compete, screw it. Long live the new! |

As far as "because it's cheap", you ain't kidding. NBC had a hand in designing the HPX300, which they're now using as their main news camera, and it costs around $8,000. The days of the $60,000 broadcast camera are gone. Quote:
I pointed to the Red 16GB compactflash card because that's the only memory card out there that's of comparable size that's tasked with recording such a heavy-duty codec. And Red's CompactFlash card is custom-manufactured for them because no other CF card can handle it. And it costs *more* than a comparable-sized P2 card. And a P2 card isn't just a memory card like an SDHC card. It's a complete microcomputer with a processor and its own firmware that handles data integrity checks, write verification, wear leveling, and file system management that protects the user from losing data if the power's pulled or the card's ejected. No other card does that. Even Sony's SxS card, the FAQs flat-out say "don't pull the card out while it's being read from or written or data may be destroyed". Pull a CF or SD card out while it's being accessed, and see what happens. Then try it with a P2 card and see what happens -- you might be surprised. You'll lose, at most, two seconds of footage and that's *it*. Anyway, it's simple: if you want to record AVCHD, there are commodity SD cards available for that. If you want to record HDV, there are commodity CompactFlash cards available for that. If you want to record AVC-Intra, DVCPRO-HD, or AVC-Ultra, those require a P2 card. Quote:
The form factor of the P2 card started with PCMCIA, which was convenient for the laptops of the day but it's hardly dependent on whether laptops have that slot! Every video format ever made has needed an "adapter" to be used with computers. Typically those "adapters" have been called DECKS, and have cost anywhere from $4,000 to $250,000. Nowadays you can directly plug in the PCMCIA card into some laptops like the Lenovo R series or any Panasonic Toughbook or just about any of the Fujitsu Lifebooks (and probably several more that I don't feel like spending time googling), or you can get an adapter (like the Duel adapter or the Addonics) for $69 to $119. Or are you trying to assert that the 110,000 P2 cameras out there in the world are somehow not working? Seems like they're working just fine. |
Quote:
Barry, much respect for you, but the HPX300 is 1/3" Cmos!!! May God give light to the ones buying it... |
Many of the reasons for the P2 card's complicated engineering are holdovers from when flash memory media wasn't fast enough to handle HD video streams. That's no longer the case. Panasonic deserves a lot of credit for being first on the scene with a workable tapeless solution. But being first in an era of rapid technological change doesn't always mean best. These days, Panasonic's over-engineering of P2 is really just overkill. Look at what Convergent Designs or Red are doing with standard-issue SD or Compact Flash cards. They're handling very high-end video and audio streams with no need for the multiple redundancy or other features of P2. And it would no more occur to me to yank a memory card out of a running camera than it would to pull an HDV tape out of a camera while the drive motor is running.
I've always been really suspect of proprietary media. In my mind, it's just an excuse for companies to charge exorbitant prices for a captive audience. If I'm shooting a feature-length documentary in an out-of-the-way location, I don't want to have find a specialty dealer to get me an extra 30 minutes of shooting time. And what happens if the company goes in a different direction, and your specialized media is no longer available? Ask anyone who's ever used a mini-disk audio recorder. As for the MSRP of P2 media, a quick check on the B&H site and others show that street prices are much closer to $800 per 16GB card. Maybe they'll come down soon, but at the moment, I couldn't buy the cards at the price you quote. |

An outdated memory technology and an obsolete bus. The development of AVC Intra 100 means Panasonic sees no need for more than 100Mbps. So why stay with P2 RAID? There is no excuse for someone buying any product that doesn't use commodity media. You are simply giving a company money for nothing. $400 is crazy expensive for likely $10 worth of parts. And, god help you if you lose or damage a P2 card in other than a major USA city. The decision by Panasonic to go P2 and to use SD chips in what they claimed were HD camcorders killed my belief in their interest in anything but maximizing their profit. And, their choice of AVC Intra 100 is a production killer when 100Mbps MPEG-2 can deliver the exact same quality as AVC 100 at this data rate. AVC Intra 100 is NOT 2X more efficient. It's not even 2X more efficient at 50Mbps. And, MPEG-2 can (and should) be edited natively with multiple real-time streams. Of course, given that SDHC capacity has now grown so high -- there is no need for AVCHD. JVC has proven that SDHC can be used at 35Mbps which is more than enough for any of the camcorders using AVCHD or AVCCAM. Another buyer money wasting move that only serves the purpose of trying to sell more camcorders that offer no more quality than does HDV. Why Sony joined Panasonic in this move is beyond me. (And, both locked themselves into MAIN Profile.) And, back to the GH1 -- not only does it only use MAIN Profile it uses a cell phone like version without B-frames which is nuts because B-frames are what makes 17Mbps compression acceptable. (And, why AVCHD when the camera only really works at 720p60 which matches AVCHD Lite?) In fact, why AVCHD at all when pure H.264/AVC works perfectly with all applications! |
Very interesting discussion with lots of good points.
Let me add my point: Having been in the pro audio world for over 35 years and having seen the technology leaps, I feel as if the same is happening with video now. When I started in 1975 to learn sound engineering at Hansa Studios Berlin, it was a costly thing to produce a record, today most music sounds the same and is produced on some kids laptop with hard&software for maybe 2k$, and has the half life of a plastic shopping bag. I see similar things happening to video.....at a faster pace but with the same results: videos made on equipment for under 2k$ with the half life of a plastic bag. |

Prior to the invention of papyrus, our ancestors put a great deal of thought into what they committed to stone. Today, young 'recording artists' learn how to do multiple takes and composites of vocals and guitar tracks in their home studios, but rarely develop the kind of musicianship that occurred when access to even such a rudimentary device as a tape deck was a rare occurrence. The same is true of video and film. The answer is to approach these new mediums with the discipline of those who came before us, and to hopefully not fall into a pattern of producing the musical or cinematic manifestation of fast food. Sadly though, as technology pushes forward, tastes change, and the thirst of the general public for the likes of Doestoyevsky and Kurosawa is being replaced with salivation over tabloids, reality-tv and four minute youtube videos about wardrobe malfunction. |
I finally had the chance to actually touch and test a RED and was very surprised to find a fully working piece of pro gear with incredible features and proprietary software, that works and is capable of stunning footage in the hands of a pro.
I am a happy owner of the GH1 and can see some surprises popping up in the near future regarding cmos cameras, but for now the RED and Canon MKII and GH1 are NOT comparable in any way IMO. I can understand the dislike for the marketing of JJ but they deliver a functioning camera at the moment and sort of revolutionized the market, and maybe paved the way for what we are seeing now with the DSLR´s and in the future with other cameras. |
As some of you know, Sony is coming out with a UMD less PSP this October with a built in battery. They claim it’s to help shrink the system but I bet it’s also to obviously prevent people from hacking the system like people been doing with a modified battery and memory stick on older PSP systems. You can have useful applications like watching YouTube videos but it can also allow you to steel games which is understandable for Sony deciding to have a battery built into their PSP Go.
In the case with Panasonic, their latest firmware upgrades for their cameras makes some of the features better but it’ll also prevent you from using third party batteries at least for now. Usually your safer using genuine batteries and yes there are some that are just as good but if anything were to happen to your camera, your warranty may get void if the company finds out. I view it like sending your car to an auto body shop and a mechanic tells you that a certain third party part works just as good. You just got to be careful. Long story short, would hacking a GH1 be similar to hacking a PSP?. If so than I would assume Panasonic got worried when they heard about the 5D Mark II getting hacked. My GH1 has the latest firmware updates and I wouldn’t want to use a third party battery or hack the GH1 anyway but I’m dying to know. |
