consumer vs. professional formats, and 24p again.
|
Yes, I saw that. Too bad there's no more info to be found anywhere. I'm very curious about it.
|
NYC conference.
Full details prob within 8 or10hrs from Tokyo Sony announcement IMO. |
The HDR-SR1 sounds interesting. What are current editing options for footage from these cameras?
|
Most interesting is that they addressed the short-record-time thing head on. In the DVD version they're using double-layer, which they say lets them get 1 hour of recording time (wonder what the bitrate is at that though? 6 megabits maybe?)
Then they introduced a hard-disk model too. They claim up to 10 hours of recording time on that (30gb hard disk?) |
I hope these have better manual control than their Standard Def counterparts.
That, and better low-light than the Sanyo HD1. EDIT: looks like they brought back the manual focus ring, dedicated mic and headphone jacks :) |
AVCHD data rate, thoughts on the format
Barry - I think 6 mbit is definitely in the ballpark - just running the math:
1.4 GB is single layer, therefore 2.8 GB is a reasonable guess for dual layer divide 2.8/3.6 converts GB/hr to MB/sec, (that's a handy bit o' math to remember, BTW/FYI) multiply by 8 to get megabits/sec - 6.3 I've posted some thoughts on the new format over at hdforindies - http://www.hdforindies.com/2006/07/f...amcorders.html Will update as more info emerges. The biggest issue I see is this - OK folks....how are we going to edit this stuff? Native NLE support is how many months away at best? As for the hard drive - 30GB sounds about right as well at this data rate....unless they are dropping the data rate even lower (as the statement implies) and it is a smaller drive. -mike |
Count me in as a HDR-SR1 fan. I want decent recording times and no media to exchange.
I didn't think they'd have product so fast. My goodness, well next years going to be a HD explosion for me I guess. |
on AVCHD
Harrison - what would you want to use it for - home movie stuff? At this point, the format is pretty much uneditable as far as I can tell - perhaps Sony will bundle something with the cameras?
As far as I can tell, you can play discs off the camera connected to TV, or copy to computer and play from there. But editing? Somebody please let me know what's possible, now or in the near future (anything beyond NLE vendors' "expressed interest")? Not picking on you, just trying to understand the usage case. -mike |
Note: I've had to do some editing here. For legal reasons, please don't post information about how to access "secret folders" on other websites.
Thanks. |
For editing, I would certainly expect that the reason Sony Vegas 7 wasn't introduced at NAB, but instead was delayed until later this year, would be to add AVC-HD support... just a guess, but I'd be surprised if I was wrong.

Long term I'm looking forward to seeing what Panny can do with AVC-Intra but the first products coming will be way beyond my budget. |
I think Cineform has suggested they'll move quickly to support new formats like this, and their past track record seems pretty good on that point. Canopus has also been doing a competent job of incorporating multiple formats, but probably not as quickly.
I'm not keen on the idea of trying to edit MPEG4 video given how tough it is to work with MPEG2, but solutions will no doubt be forthcoming. What I'd like to know is when we might see more professional cameras based on this recording format, like the one proposed by Panasonic. |
Didn't know the news/model numbers were leaking already, but our NDA doesn't expire until the announcement tomorrow.
Suffice it to say for now, these are *consumer* camcorders. Not professional by *any* stretch of the imagination. Doesn't mean they're not useable, but they are built for, aimed at, and supported for mom/pop shooters. |

There is also some discussion on the recent announcement of 1 hour of HD on 4GB, which is about 9Mb/s. But I mention that on the Ambarella site they also talk about HD in 6 mbit/s (I think) so I fear that this is also possible, and undesirable: http://www.dvinfo.net/conf/showpost....8&postcount=93 |
The link to the SR1 hard drive model seems to be missed:
http://www.camcorderinfo.com/content...er-HDR-SR1.htm The article does claim upto 24mb/s recording (phew, what a relief). |
This thing sure looks a lot like the HC3 camera. If I had to make a guess I would say it is almost the same with only the recording media and format as the main change. The new cameras seems to use a CMOS chip and it makes sense that SONY might use the same chip to try and bring the cost down. Is there really a whole lot that could be done to make a 1/3" CMOS chip look any better than the current cameras? The lens is still small and it is still a CMOS chip and a single chip. Unless this chip has a native 3840x2160 pixel count that can be sampled back down to 1920x1080 for higher detail from a bayer filter I do not see this camera as light years ahead of the HC3.
Perhaps when SONY says 60 minutes on a dual layer disk they mean that is how much time you can get at the lowest setting. Kind of like how some DV cameras would claim to be able to record 120 minutes at LP on a 80 minute tape. Perhaps there are multiple bitrates and 24 is actually the highest but with very short record times. Can a camera based DVD drive even run at 24 mbits/s? Avid Liquid can already edit WMV files including H264 in realtime while mixing with other HD and SD formats. I'm not sure how much different AVCHD is to H264 WMV files but it shouldn't be hard for Avid to add support. Of course as of right now Avid has not joined the AVCHD group so who knows. |

Yes, 1/3rd inch can be improved. Their are various noise reduction, global shutter, fillfactory, and sensor circuit techniques (not to mention Foveon like three colored pixels) as well as micro-lensing techniques. We can guess that Sony is using some of these already to a good extent, but one that it vary important is multi-slope and per pixel dynamic gain, good for extending latitude and for using a faster lens without blowing out. I have seen an article (CC I think) where a Sony boss mentioned something that sounded like these latitude extending features, and some of the Japanese marketing blurb (haven't seen the English doco) seemed to indicate this. Depending on what Sony is doing, it should be possible to get a number of stops noise sensitivity and latitude. |
Well, if these things have true 24p on them, then things could get pretty interesting.
|
How big are the CMOS sensors and even though officially recording type has been announced will these cameras have the capability of recording 1080i and 720p at a touch of the button? are all the cameras capable of recording in 24p? I don't think they would, I bet you that Sony and Panasonic have a prosumer card up their sleeves. I am looking forward to seeing that, oh BTW AVCHD is GOP based right?
|
I bet it will have that crappy "Cinema Mode" (i.e. CineFrame). Which is pretty sad, because the technology is right there. CMOS sensors can do progressive scanning right? 720/24p is a part of the AVCHD codec parameters. So why would it not have 24p capability? I'll tell you why. Sony has never offered 24p as an option for any of there consumer or prosumer lines and I don't think they will start now.
Don't bet on Panasonic making a comparable product with 24p either. It will completely destroy any market for the DVX100 and it will cut into the profits of it's reigning golden boy the HVX200. Your best hope would be that Canon uses there AVCHD license and makes a 24p prosumer camera. It would definitely fill a gap in there line. Or maybe JVC will purchase the license and do something, I doubt it though. Just because consumers want something doesn't mean the companies will listen, unless of course it benefits them. It's to bad, because it would make things interesting. Also it would give aspiring young filmmakers something they could use well within a respectable budget. |

Specs from Sony Japan
I found some interesting info on the new UX1/SR1 specs page on Sony Japan's website.
UX1: http://www.sony.jp/products/Consumer...feature01.html SR1: http://www.sony.jp/products/Consumer...feature01.html The 2 cameras are nearly identical except for the storage medium. Both appear to have the same sensor/lens combo as the HC3, in addition to a DD5.1 built-in mic (or DD2.0 when using the stereo mic input) and 3.5" LCD. Both have a manual control ring at the front of the lens, which can be toggled between control of focus, exposure, or AE/white balance shift (zoom was not mentioned). Both have USB2 but no Firewire. Both support only 1080/60i in AVCHD mode. There is no mention of Cineframe or any other progressive recording mode. Both also have an SD mode, recording 480/60i MPEG-2 at 9/6/3mpbs. The UX1 (DVD version) records AVCHD at a max rate of 12mbps (HQ+) mode, storing 27mins on a dual layer DVD-R or 15mins per side on a single layer DVD-R/RW. The lower rate modes are 9mbps (HQ, 35/20mins), 7mbps (SP, 45/25mins), and 5mbps (LP, 60/32mins). The recorded discs can be played in a PC, Playstation 3, or other AVCHD-supporting player, but not standard DVD players. The SR1 (hard disk version) records AVCHD at a max rate of 15mbps (XP, 4:00hrs), and also records 9mbps (HQ, 7:00hrs), 7mbps (SP, 8:30hrs), and 5mbps (LP, 11hrs). I guess anyone who was expecting 24mbps or 1080/24p will be a little disappointed now. In theory, given an ideal encoder, 12mbps H.264 would probably look as good as HDV's 25mbps MPEG-2. But given the realtime requirement and size/power limitations of these consumer camcorders, I don't think it will beat HDV. |
Jason thanks for the info, this is a very predictable move for Sony, ofcoarse there would only be one recording type, which is 1080i60 but when a prosumer camera using the AVCHD comes out, then more features will be available like 1080p24 or 720p24, there would be no way a camera for consumers and costing US$1500 will have most of the features discussed.
|
Jason Livingston,
That’s very confusing when Sony promised up to 24MBPS. Either these articles need to be corrected by Sony or this only means that one more AVCHD camcorder is on its way that will have a compression of 24MBPS. |

2. Implementing multiple clocks is very costly. Just ask any camera manufacturer, or manufacturer of any timed device. 48Hz, 50Hz, 60Hz clocks all come at a price. The point of these cams is to be high quality but inexpensive. 3. Why any other resolutions? Sony, like most of the broadcast world, knows it's a 1080 world on the broadcast and display-purchase side from a consumer standpoint. This is part of why many of their cams offer HDMI out as well, making it easier for consumers to connect the cams directly to their 1080-ready displays. But the most important thing to remember that seems to be getting lost in the discussion of the AVC-HD camcorders, is these are designed EXCLUSIVELY and only for the consumer channel. It's not usable for broadcast at all, IMHO. AC3 in-camera? C'mon...you guys know better than to believe these are for broadcast. They're mom n' pop cams. Disc or Disk-based, 4 Megapixel stills, single CMOS imager, great price point...great for consumers. No one had kittens like this over the HC3, why are you having kittens over AVC-HD? |
Okay I get all that. I thought you could get a progressive image off of CMOS chips. However, If AVCHD is "EXCLUSIVELY" a consumer format and 24p is not (yet) considered a consumer option. Why waste time implementing 720/24p into the specs of AVCHD? The cheapy Samsung HD has 720/30p. I understand these cameras are not meant for broadcast, but for amateurs and enthusiasts, 24p would be a good selling point. When I was 14 years old I bugged my parents ad nauseum to get a Canon 8mm camcorder that cost $1k at the time. Granted I had to pay for half (okay maybe like a 1/3rd), but still they could see my enthusiasm for filmaking and relented.My parents nor I would have been ablre to purchase something in the price range of the DVX. My point here is that for upcoming filmmakers a camera with 24p in the price range of $1500-2000 would be a godsend. Not to mention a great B camera to compliment other 24p cameras.
As I stated in a previous post, I think it just reeks of marketing BS. I don't think there is a major cost prohibitive factor at work here. |

Douglas, whatever they have told you, or have shown you, is probably only the short term information/outlook (for the next 4-6 months) meant to keep people limitedly informed and not interfere with sales of the new cameras, and I suspect that 24mb/s, 24p, and Tru1080 will be reserved for prosumer models, late this year or into next (hopefully not NAB). The question is, will we ever see the HVX AVC Intra, or will that be reserved for true pro models (hopefully not). Will 15mb/s AVC compete with 25mb/s HDV? There are advancements over HDV's mpeg2, if they choose to properly support them, but even then I don't know. For instance, 15mb/s is still 15mb/s VS 25MB/s HDV, how will scene changes (low light noise and motion) suck this up and be rendered. These changes are the extremes that tax low bit rate codecs the most, can h264 make up the difference. I think if h264 implemented fully and well, it might win in scenes with little scene change, and not in scenes with massive scene changes (like low light and movement) in this camera. So, still consumer, now if it can only render pictures like the birthday scene picture on it's web pages. |

So just hold on a while longer, and maybe you'll get that affordable 24P cam yet. And remember, if you're REALLY serious about that 24P look on a tiny budget, you can always go PAL. A PAL HC1 either deinterlaced or shot in CF25 mode and slowed to 24fps is a pretty nice budget tool... www.philipwilliams.com |
It's very tempting to believe that the HC3 will be pulled in favor of this. It looks like the HC3 body with a few HC1 options put back in. However, consumers want to shoot and watch HD material on their HDTV's and don't want to bother with editing. This makes for happy customers and protects Sony's entrance fee into the pro market.
I'm sure that Sony would rather sell an A1U in favor of a pro whom rather have and HC3 for the image only, placed into harms way, or as small form factor. They can get another $1000 that way. Those of us whom already have an HC3 or HC1 in our arsenal may be lucky if this turns out to be the case. Of course, I could be blowing smoke, but it makes sense from a bottom-line point. |
Tony, it's not marketing BS it's the fact that extra features cost money for R&D and Patent licensing and the fact that if these cameras did have 24p and other features how many CONSUMERS will appreciate and take advantage of this, to them it would seem too juddery and stick with 60Hz.
There are people like us, and then there are consumers. Guess who outnumbers who. |

Dont you think that this will be the case for quite some time? Everyone has this dream/fantasy/nightmare of killing film but the ONLY way you will ever get CLOSE is uncompressed. Just as the photo market is quickly going RAW and less compressed, I see the professional and even pro-sumer market moving this way as storage solutions become cheaper and mroe reliable. Compression will be king for delivery but not for acquisition. I mean, think about audio, it is being delivered compressed over the air or SUPER compressed over the internet/mp3 but nobody is even TALKING about acquiring anything that way. Most people have moved to ProTools HD 24bit, etc. ash =o) |

It would not make sense at all to pay the 24P licensing fee for such a camera. AFAIK, the license is per camera made... ash =o) |

2. The 24p license ain't cheap, and every penny in cost equates to at least 30 times that in end retail price. 3. You *can* get a progressive image from CMOS chips, I didn't suggest you can't. What I suggested is (and know very well from a variety of external sources) is that Sony considers AVC-HD as a consumer format. I'm quite well aware of what Sony was doing with this format several months ago, and just as well aware of what's coming. 4. You're welcome to suppose it's marketing BS, but having been around this industry for as long as I suppose you've been alive....it's not anything of the kind. |
IF ANYTHING sony might release a camera through the broadcast division very similar to what they have done with the HC1 to the A1 and the FX1 to the Z1, and probably include the 24p framerate. This is the camera to look out for, prosumer or pro or what ever you want to call it, this would be the hero cam for AVCHD. Panny will probably do the same.

Tony, you just proved DSE's point... you say you are a passionate filmmaker but cameras like these are not aimed at filmmakers... they are CONSUMER cameras and it is a CONSUMER format. As for the 24P license? Last I checked the cheapest cams with true 24P retailed for over $3000.
As a filmmaker and a professional there are many features that you need that the consumer MASSES do not, you will always pay a premium for those features because the competition is less and the market smaller... ash =o) |
I guess my point was that 720/24p is in the specs for the format. If AVCHD is only aimed at a consumer market (as DSE claims). What's the point of making it a part of the official specs if no company plans on using that resolution and frame rate. I don't know much in this given field, but I can read and I do know that 720/24p is a part of the format. I get that Sony isn't inclined towards those ends, but claiming a strictly consumer base for AVCHD seems a little premature when the format specs dictate that it is geared for prosumer needs as well.
My only argument was that AVCHD is not going to strictly be a consumer format. That was my only point. |
