Press Release: HMC150, "the new DVX"

Bob Diaz Is Back From NAB.....

Bob Diaz Is Back From NAB.....

It's been 2 world wind days at NAB and I'm going on very little sleep right now. So, forgive me if I don't cover all the and questions I know everyone has tonight. I have interviews with Barry Green and Jan about the new cameras, Thursday (later in the day) I'll post Barry's interview and Friday (later in the day) I'll post Jan's interview. Other things about NAB will follow.


First the good stuff:

The HMC150 camera I saw was working; I assume it is still a per-production model, BUT at least I could see how it functions. It's hard to fully judge the image at a trade show, because I can't do the kinds of tests I want to do. However, form the simple tests I could perform, the image looked great. Keep in mind that the lighting in the section of the Panasonic booth were they were showing the HVX150 sucked...

Then again, the limited lighting showed to me that the camera is able to handle the poor lighting conditions we end up in. As for playing with gain, it's all a matter of how high do you want to go before you find the noise in the image too strong. Some will see the +6dD gain and say that's it. However, while there was some noise at +9dB gain, it really wasn't too strong and you had to be looking for it. At +12dB it was easy to spot, even then, there seemed to be a softness to the noise, it didn't seem as strong at most image noise I've seen.

The new improved CCD is better at lower light levels, but until we can do a side by side test we can't say for sure what the increase in low light levels really is. Barry's guess is 1/2 a stop, but this is only a guess.

The best part of the camera is how it feels in the hand. This is one of those parameters that's impossible to express in a specification sheet. OK, it's lighter and thiner than the HVX-200, but it's more than the light weight, it's the feeling of balance. For example, the EX-1 is a great camera, but the weight of the camera tends to tip it to the side. Now if you hand hold an EX-1 for long periods of time, your hand will tire. In the case of the HMC150 and the 170, both feel right and it takes almost no effort to keep the camera upright.

The camera should come out in October.


Now some bad news: (Please don't shoot the messenger!)

I came within 12 inches of getting the card in the camera, BUT the Manager from Japan said, "NO!" His reason was, "Format not ready, not stable." So, sorry everyone, I don't have that, but I have lots of photos and a short video taken from my camera of the HMC150.

Time Lapse; sorry but right now it appears that we won't see that feature on the HMC150. Right now it appears that the odds of this being a feature are small, but not impossible... we will see.


Overall Impression:

My final judgment of any video camera has to wait until real world tests can be performed. (Which requires that the unit be in production.) Right now the camera is still undergoing the final development steps. HOWEVER, I do like what I see.

So far, it's still looking very interesting; the feel and operation seem just right. The "big brother" to this camera is the 170. The 170 uses P2 and has more features. You can expect the price to be close to the HVX-200a price.

Both the HMC150 and the 170 use the same CCD and same lens. IF we ignore the CODEC differences, the 2 cameras should produce the same image. The HVX-200a uses the same CCD, but the glass is different. Still, the image should be about the same. So, could the HMC150 be used as a second "B" camera? It seems reasonable to say yes, because the CCDs match.

Without question, if you spend more money, you get additional features on the 170. Still, the 2 cameras are for 2 very different markets. I get more into that at a later time...


There is so much more I'd like to say right now, but I'm really tired out and I will spell it out tomorrow, after my brain does a re-boot................ ZZZZZZZZZZZ

No, only 1 SD or SDHC Slot.

At the maximum data rate, 21 Mbps/24mbps peak, the 32GB card lasts 3 hours.

Lots of Photos....

Lots of Photos....

Funny thing that you should say that.... The unit I saw had only 6.
OK, so I went a little photo crazy, but take a look:

More....

Now take a look at the HPX-170.

There's not a whole lot of difference between the HPX-170 and the HMC-150.

You Tube Video of The HMC-150

You Tube Video of The HMC-150

Sorry, but I have no idea about the flip function.

I just posted a You Tube video showing the camera. It's about 2 minutes long and it was not easy to play with the camera for that long without someone else wanting to pick it up and take a look at it. Within the limits of the You Tube resolution, you can see several functions on the camera. I just wish I had a bit more time to record it before someone else picked it up...

I'm updating my WEB page on the HMC-150 it should be ready soon:

Confirmed that the 170 does. Looks like the 150 does as well, but the 150 had a remaining-battery-life meter that was showing the actual minutes of battery life left. That might mean it's using a new/smarter battery technology.
 
The new battery family Panasonic developed, has a built in fuel gauge and also smart communication with the camera, similar to what Sony is doing for years with their L batteries. According to the Panasonic rep, the camera would reject the batteries that can not id themself as true Panasonic. This was a recent conversation, about 4 weeks ago at a smaller regional trade show in Massachusetts. We had a booth their, demoing our battery chargers; the rep brought one of these new batteries and plugged it in the charger, to show me how smart they are and how they only can be used with their own. Surprise! They started taking charge, recognized by our charger :-) He was surprized a little. So I do not know if some of what he said is true. It could be that as the Sony cams, the new Panasonic cams will start rejecting older or knock off batteries.
 
The running times for the different memory cards will vary depending on the type of footage recorded, but as a general rule, at the highest data rate:

32 GB = 180 minutes (3 hours)
16 GB = 90 minutes (1.5 hours)
8 GB = 45 minutes (0.75 hours)
4 GB = 22 minutes (0.37 hours)

Remember fast action with lots of fine detail changing requires more bandwidth, thus less recording time. (Multiply the time by 0.87 for a rough estimate.) If you push the gain to a higher dB setting, the CCD Noise will also eat up bandwidth.

Images with little changes from frame to frame require less bandwidth, thus have longer recording times. (A wild guess would be to multiply the time by 1.14, however until we can test it, we won't know for sure.)


Battery Life Time Measurement:

Without question, the smart technology that has a small on board micro controller to keep track of the battery is the most accurate way to measure remaining battery life. There are other ways...

A simple voltage to running time conversion is possible, BUT is NOT very accurate. Temperature, age of the battery, and a surface charge can yield rather inaccurate readings. (A surface charge is where we only charge the battery for a very short time, like a few minutes, which results is a higher voltage that does not reflect the true remaining capacity of the battery.)

If we measure the rate of change of the voltage of the battery over time, we could get a better estimate of the running time. This could be fooled if there's a surface charge that is being "burned off", but the longer the camera runs, the more accurate the reading.

I regret that I was so focused into looking at the image, the feel of the camera, the waveform monitor, the buttons, the image noise at higher gain settings, and other major things, I forgot to look at some of the other details.

Thus I can't say what the outcome is for the battery:

(1) Panasonic is switching to a new smart battery and the HMC-150 can only use this battery.

(2) The HMC-150 can use the new smart battery AND the older style battery, but you can't get a running time with the older battery.

(3) The running time counter is just using something like the rate of voltage change over time to estimate the likely running time. (Not very accurate, but better than a simple bar graph.)

The photos I took do not show that the rear viewfinder is able to move anywhere from a horizontal position to a vertical position; very nice for those low angle shots. In looking through the rear viewfinder, it looked to me a lot like the HPX-200's viewfinder with a lower pixel count than the side viewfinder. (I could be wrong about that, but that's what it seemed to me.)

The side viewfinder appears to be 4:3 which allows for information to be displayed outside of the image. It also appears to be the same resolution as the HPX-200's side viewfinder. There are improvements in the focus system; which will make it easier to focus the camera.

It is possible to have both the side and back viewfinders lit at the same time. While this eats up more power, it does allow you to quickly switch from one viewfinder to another.



Side Issue, NOT HMC-150 Related:

In the April 14 Issue of TV Technology, there an article on 720p and the man who helped promote it. The article starts on page 1 and continues on page 28. Of interest is Panasonic's part in the 720p promotion (see page 28).

http://www.nxtbook.com/nxtbooks/newbay/tvt_20080414/

I like the quote on page 28, "Among engineers, there is agreement. When showing 1080i, 1080p, and 720p - 720p is better." Most likely he was thinking 1080/60i, 1080/30p, and 720/60p, because both 1080/60i and 1080/30p will not do as well with fast action as 720/60p. ... This sounds like a good topic for another Podcast; there's a lot more to cover here...

You'll know I'm a true neophyte by my questions, but suffer me:

1. If the HMC 150 is HD only (or any HD-only camera for that matter) are you able to make through editing software or otherwise an output to SD DVD?

2. What do you guys think of the reliability issues raised ealier with the memory cards vs P2?
 
Please understand that the only "dumb question" is the question that is never asked. I tell my students that all the time, because the point is to understand as much as possible and not to sit around not knowing.

With an HD ONLY camera, we would shoot in HD, Edit in HD, and output the final edit in whatever format you wish to use (SD or HD). The HD Editing software should allow an option for HD or SD output. In the case of wanting SD output, I did take an HD master, output (export) the final as SD, and burn that to a DVD. In fact I did do that with one video. The results are VERY good.

I would suggest shooting in in 720/60p, unless you want a 24p film look. With 60p, you can do a slow motion or freeze frame without any interlace problems.


As for "reliability issues", assuming that one did NOT purchase a really cheap SD card, I see no reason why this should really be an issue. In order to record at the highest data rate on the HMC-150, you will need a class 6 SDHD memory card. (Class 6 = 6 MB/Second = 48Mb/Second; where MB = Mega Bytes and Mb = Mega bits; 8 bits = 1 Byte)

An argument can be made that P2 is more reliable, because there is never a chance of "cheap quality" P2.

I'm sure that once the HMC-150 comes out, we'll see reports of which brands of memory cards users have found to work OK. Panasonic will be the safe bet, but users will test other brands and report the results on this forum.


Also, the link found in this message is to my Podcast. There you will find several Audio Podcasts about Technical Topics. This is an ongoing thing, so the list is always growing. The basic plan is to provide helpful technical information to users.


Sincerely,

Bob Diaz
