Sanyo’s VPC-HD2000A boldly goes where no consumer camcorder has ever gone before: 1080/59.94p
Allan Tépper | 11/20
Sanyo shows its willingness to stretch the limits of format recordability.
At the dawn of affordable professional HD video camcorders, JVC first offered recording only to 720p, Sony first offered only 1080i recording, and Panasonic offered recording to either of the above (even though its original sensors had a native resolution of 960x540, so any HD recording was interpolated). Nowadays, many of the latest offerings from the pro divisions of JVC, Panasonic, and Sony embrace the option of recording 720p, 1080i, or 1080p in a single camera. However, because the maximum framerate available with 1080p in these affordable professional HD video camcorders has been limited to 29.97p, those producers who favor progressive production have faced a tradeoff: either favor spatial resolution (1920x1080 at a maximum of 29.97p, for ultra sharpness and less smoothness) or favor temporal resolution (1280x720 at a maximum of 59.94p, for ultra smoothness and less HD sharpness). Many of our readers have already read that debate in my When 25p beats 24p article. For many, the idea of actually recording 1920x1080 and ±60 progressive frames per second has required a camera like Sony’s F23 camera, whose official price is US$150,000 without a lens or other accessories, and has been amply covered by Art Adams and Adam Wilt here in ProVideo Coalition magazine. (The RED ONE camera also offers 59.94p at 3K windowed mode for US$17,500 plus lens and accessories, although many RED ONE shooters prefer to shoot 4K to retain a familiar focal length, where they don’t get 59.94p.) Now Sanyo has changed that with a few of its consumer HD camcorders, of which the most interesting is the US$599.95 VPC-HD2000A.
VPC-HD2000A sensor and focal length
The VPC-HD2000A’s sensor is a 1cm (1/2.5 inch) CMOS which according to Sanyo uses 8 million pixels in still photo mode, 5.31 million pixels in HD video mode, and 2 million in SD video mode. Focal length does not change at all when using any of the video modes (including 1080p, 1080i, 720p, 540p (so-called “iFrame”), and 480p), but it does become more wide angle in still photo mode. Video zoom range is 41.7-666.9mm (35mm equivalent).
VPC-HD2000A still picture specs
- 4000x3000 (±12 million, evidently interpolated)
- 3264x2448 (±8 million pixels)
- 3264x1840 (±6 million pixels, 16:9 aspect ratio)
- 1929x1080 (±2 million pixels, 16:9 aspect ratio)
- 1600x1200 (±2 million pixels)
- 1280x720 (±900,000 pixels, 16:9 aspect ratio)
- 640x480 (±300,000 pixels)
High-speed photo specs
3264x2449 (±8 million, sequential photos)
2299x1712 (±4 million pixels, sequential photos)
VPC-HD2000A video specs
- 1920x1080 progressive @ 59.94p
- 1920x1080 interlaced @ 59.94i
- 1920x1080 progressive @ 29.97p
- 1280x720 progressive @ 29.97p
- 960x540 progressive @ 29.97p (called iFrame by Apple and Sanyo)
- 640x480 progressive @ 29.97p
- 448x336 at 239.76 fps (high speed for slow motion, without post)
- 102x108 at 500 fps (high speed for slow motion without post)
The 540p mode which Apple and Sanyo homophonically call iFrame has been covered both by me and by Matt Jeppsen. As of publishing time, we still have found no evidence to indicate that this format actually uses i-frame encoding. It is interesting to note that apparently even in Europe, Sanyo is offering the same framerates listed above: no 25p or 50p in the VPC-HD2000A even in the European model, but these speeds are fortunately available in the Sony F23 camera. Obviously, the VPC-HD2000A and F23 don’t compete, but they do have the so-far rare 1080p59.94 recording mode in common. It is also interesting to note that Sanyo loves high framerates, but doesn’t love low framerates, since there is no option for 23.976p either.
Like other Sanyo HD camcorders I’ve seen, the VPC-HD2000A records H.264 video using the universal MP4 suffix, rather than a proprietary QuickTime wrapper or a complex AVCHD file structure. This offers certain advantages, since it frees Sanyo from playback limitations and allows 1080p59.94 recording (which is not part of the published AVCHD spec), but prevents an instant and direct clone to a video Blu-ray disk. (It is of course possible to clone the footage to a data Blu-ray disk.)
Sanyo’s 1080p59.94 recording is legitimate, while JVC consumer’s currently is not
JVC consumer division was the first consumer company to promote 1080p59.94 camcorders, but (at present) the JVC consumer cameras really record 1080 at 29.97p recorded over 59.94i, and advertises it as “1080 60p”. Fortunately, Sanyo’s claim to 1080p59.94 is strictly kosher!
VPC-HD2000A audio features
- External microphone input (unbalanced)
- External headphone output
Why bother with 1080p59.94 if it can’t be broadcasted over the air?
You may be asking the above question. Here are some answers:
- Many of today’s productions are not broadcast over the air anyway. Even YouTube just announced that it will soon support 1080p, although hasn’t yet mentioned the maximum framerate. So far, YouTube says: “The video frame-rate should be the same as the original where possible.”
- 1080p59.94 would be great to shoot slow-motion footage for a project that is for a medium or low framerate 1080 project (i.e. 23.976p, 25p, or 29.97p) without sacrificing any spatial resolution compared with the rest of the 1080p shoot.
- 1080p59.94 would be great for a 720p project to allow for magnification in post, without spatial resolution loss (or less spatial loss if you magnify too much!).
VPC-HD2000A footage shot by Jorge González of Acquest Multimedia
See the video page to see 720p footage shot with the VPC-HD2000A from your computer. If you are reading this on your iPhone, tap here to see an iPhone optimized version of the same video.
Many readers will recall that Jorge González of Acquest Multimedia in Miami had purchased, tested, and then returned a Kodak Zi8. You will recall that Jorge’s main HD camera is currently a Panasonic AG-HPX500, which you may know is a 2/3” model which lists for US$14,000 without lens. Jorge had purchased the Kodak Zi8 mainly for his wife, but returned it because of poor stabilization and poor minimum distance with its fixed-focus lens. After returning the Zi8 to Kodak, Jorge read my article called Apple & Sanyo embrace new homophonic video format: iFrame. After reading that article, Jorge became intrigued by the Sanyo VPC-HD2000A, but not because of the homophonic iFrame mode, but because of the 1080p59.94 mode. However, since Jorge knew that the above video was for the web, he shot it it 720p29.97, edited the footage using the new ProRes422LT códec, and gave me the master in that códec. I then determined the TOQ (Threshold of quality) using DVKitchen’s SampleLab and then encoded H.264 and embedded into a Flash player for the web. In this case, the TOQ for this footage turned out to be 3600kilobits per second, due to the extremely fine detail in the trees. Since some of you will also want to see the camera’s performance in 1080p59.94, here’s a link to download raw footage in that format. According to the QuickTime Player’s Inspector, these clips were encoded by the camera a little over 24 megabits per second.
Pros
In my opinion (and Jorge’s), the Sanyo VPC-HD2000A produces impressive HD images if you shoot in any of the progressive HD modes. It is one of the best consumer HD cameras under US$1,000 that we have seen to date. Jorge decided to keep this one for his wife, and his whole family is happy. He just ordered a wide-angle adapter for it.
Cons/What the Sanyo VPC-HD2000A is not
The Sanyo VPC-HD2000A is not a professional HD camera. The stabilization is not good. Its physical appearance will not impress your clients. It does not have a removable lens, and it won’t help you reduce depth of field. It does not have balanced audio, nor does it have any 23.976p, 25p, or 50p mode. The Sanyo VPC-HD2000A unfortunately uses the lame FAT32 formatting, instead of superior HFS+ formatting. Especially since Sanyo freed itself from the AVCHD restraints (which allow the VPC-HD2000A to record 1080p59.94), Sanyo should take the next step and use HFS+ to allow for long clips to reside in a single file.
Conclusion
If you need a consumer camera for under US$1,000, the Sanyo VPC-HD2000A is an excellent option, and Sanyo should hire William Shatner to be in their TV, radio, and podcast spots and read the title of this article (especially since I wrote it without any split infinitive). However, for professional use for under US$150,000, we may have to wait until at least 2011 to see a camera with 1080p59.94. In the meantime, I love 720p50 and 720p59.94, especially when they are oversampled from a sensor that has higher spatial resolution! Fortunately, there are many cameras available today with that combination 
Disclosure, to comply with the FTC’s new rules
Sanyo is not paying Allan Tépper or Jorge González to do this review, nor is Sanyo giving Allan Tépper or Jorge González a free unit in exchange for this review. Jorge González had to pay for his VPC-HD2000A.

Erm… all that is good but you are not mentioning the bitrate. The bitrate is very important here, because at 60 fps you need that extra kick. So if that camera does 1080/60p at, like, 16 mbps, in my opinion, this is not enough.
Not to mention the very video-y look this cam produces (I just checked a sample video off of it): over-contrasty and over-saturated. There are no many color settings on this cam to reduce the effect considerably. The only good thing it has aside its 60p ability is its full manual controls.

Eugenia,
The last two sentences of the footage section are: “Since some of you will also want to see the camera’s performance in 1080p59.94, here’s a link to download raw footage in that format. According to the QuickTime Player’s Inspector, these clips were encoded by the camera a little over 24 megabits per second.”
So I did mention the bit rate of the 1080p59.94 footage.

I’m sometimes given to quipping “This changes everything!” at the most mundane of announcements, that really change nothing.
So now I think it’s dawning on me that I need a quip for something that really does…
My big puzzlement is why the established players couldn’t have done this first.
Does this herald the emergence of Sanyo into the field of bigger and better things for the prosumer video space?

I would not be happy if they used HFS+ since no Windows PC can read from it. FAT32 is there because it is cross-platform compatible. Also, you can record a 4GB clip on FAT32. That should be 15 minutes or more at the normal AVCHD bit rates. Why would you want a clip longer than that for anything but recording a speech?

Consumer JVC camcorders do not record 1080 at 29.97p. They do not record progressive at all. All they can do is 1080i29.97, some models have 60p upscaling via HDMI, a lame non-feature.
1080p60 makes sense when the camera indeed resolves 1000+ lines. I doubt that the small Sanyo resolves more than 700 lines, so I don’t see real benefits of 1080p60 produced by a consumer cam over 720p60 produced by a pro cam. I bet that XDCAM EX footage recorded in 720p60 and scaled to 1080p would look no worse than 1080p60 from this small cam.

In my opinion, all non-AVCHD tapeless camcorders should offer HFS+ instead of the lame FAT32 format. Too many manufacturers of cameras and disk recorders have unfortunately chosen the lame FAT32 format, and then have had to create elaborate schemes to compensate for FAT32’s many limitations. Even though these workarounds can eventually work, they do so at the expense of showing the user a bunch of sequential files for a large clip, instead of a single file. Whenever I talk to manufacturers about this, they usually say that the are looking for cross-platform compatibility (as you did). I respond that they should use the best format available (HFS+), instead of wasting resources with elaborate, counter-interactive workarounds. Any Windows user can buy and install MacDrive for under US$50 to make Windows compatible with HFS+ and then reap its benefits of a simplified user interface when seeing a single large file for a single large clip. There are many people who shoot uncontrollable and unrepeatable events. I applaud AJA for making the best decision with the KiPro,

With your first paragraph, we are really saying the same things with different terminology.
Regarding the bet you made in your second paragraph, I would make the same bet!

Alan, you said: “the JVC consumer cameras really record 1080 at 29.97p recorded over 59.94i”, which implies something like 1080/29.97PsF. While on contrary, consumer JVC cameras do not record neither 30p nor 60p, they only record native 60i.
I am all for a better file system, but I am against paying $50 just for being able to read files off a card. If plain old copy/b works, then I’d rather use it, no problems to me.

Because of the fact that those JVC Everio cameras that promise “1080 60p recording” use a CMOS sensor which is (by its own nature) progressive, that’s why I said that it recorded that signal over interlaced 59.94i. But we agree that they are lying. Sanyo was the first to do it as stated in a consumer camcorder.
Considering your opinion about not minding about FAT32’s limitations, then perhaps the camera manufacturers should include a an OEM version of MacDrive with cameras, and they would get billed only if and when a Windows user activates it. You as a Windows users would get a better result, without having to pay for it. The Mac users would also receive a better result.
