JVC GY-HM100 - 35 Mbps

I wonder whether 1/4-inch sensors with, um, "spatial offset" is the same hardware that was/is used on the HDC-DX1, HDC-SD1, HDC-SD3, AG-HSC1U and AG-HMC70? If so, these sensors are SO prone to vertical flare, but otherwise produce a nice picture. I have the SD1 and the image is not very detailed on busy scenes, but I attribute this to low 13Mbps rate of the first incarnation of AVCHD. With 35Mbps MPEG-2 things should look a bit better I think.

B&H posted the price for the HM100, $3.5K: http://www.bhphotovideo.com/c/produc...specifications

This is the same price that the HMC150 was originally priced at B&H. If the HM100 will follow the HMC150 pricing, it will cost about the same.

Comparing the HMC150 and the HM100, 1/3-inch sensors and 21Mbps AVCHD on one side, 1/4-inch sensors and 35Mbps MPEG-2 on another side. Both cams use pixel shifting. The HM100 will come with a removable carrying handle and an external XLR shotgun mic and is 50/60Hz switchable right off the box, you can have the same functionality with the HMC154, but it is more expensive and is not sold in the States. I like contouring for focus assist better than magnifying of the center of the frame.

I would pay $2.5 for the HM100 to have it as a serious hobby-cam, I will not pay $3.5K for it, I'd rather buy the HMC150.

By the way, the new consumer HS300/TM300 will have 3MOS setup with 1/4-inch sensors, each 2Mpixels, no shifting! Panasonic pushes older tech to JVC?
 
I'm actually the opposite. Since Final Cut doesn't support AVCCAM, I would much rather shoot with the HM100 and not have to worry about any type of conversion in FCP.
 
The MPEG4 Part 10 algorithm is much better than any MPEG2. It appears to be under sampled, which makes little sense in 2009. The built in glass seems no better than other cameras in its price range. It may make sense if speed to FCP is a primary concern, other wise how is it better than an HMC150?

P.S.
My guess is a Canon HF S100 with over sampled 1/2.6 sensor, probably equal and possibly better glass, 24Mb/s AVCHD encoding and the option for HDMI output would produce better images.

P.S.
With an adapter, you should be able to use Class 6 SDHC in an EX1/3

Agreed! :) The AVCCAM footage is better quality than MPEG2.

The HM100 has two slots instead of one and they span which is pretty cool.

Hoodman announced at NAB that they have a new SDHC class 6 card to SXS adapter that looks pretty cool. They are pushing their own cards though which are kind of steep so I would like to see some testing to see if the Transcend cards would work.

The Hoodman rep told that there are some limitations to the adapter so you're not out of the woods completely. If you're shooting SxS than it would be recommended to keep at least a card or two on hand at all times.

I have not used the JVC GY-HM100, but I have used the Canon HF S100. Very impressive image, much better than it has a right to be for the price point. Transferred directly into FCP using Proress 422 and monitored on a 52" Samsung 1080P LCD. In a word, "stunning".

If the HM-100 can better the image, I would be surprised. The Canon image is superior to my HVX-200 in many ways.

Now if Canon would apply this thinking to a larger professional package, and not get greedy on the price point, they will have a winner...

You can't have 1920x1080 on a 1/3" CCD

I agree that these chips don't, but what do you mean can't?

I certainly would not want it --- the noise and light sensitivity would be low (not to mention I hate the deep focus of 1/3"). But do you mean for some technical manufacturing reason it's impossible?

Well, you could put them on there, yes -- but could you do anything with them? That's the question, and perhaps the phrasing should have been "you can't make a viable HD camera with a 1/3" 1920x1080 CCD sensor." The heat involved in trying to read that much data off a CCD would make it pretty much impossible; maybe with liquid nitrogen cooling... :thumbsup:
 
Has anyone a idea if there will come extra battery capacity for this camera ?
I mean, i have shot will all HDV camera out there and have been spoiled with running times of 5 hours or more..

Seems 2 hours is a bit sad in my opion..

So, hopefully they bring out better capacity
