Clip was encoded to WMV-HD 1280 x 720p, 2 pass VBR, 6492 kbs.
The file size is 5mb. You can download it HERE (http://vsdrives.com/movies/Tumble.wmv)

so how did you get it to look that good? did you edit the colors at all or was the scene just well lit outdoors I mean? is the gr-hd1 quality really that good?
Tom Roper
All I needed was the golden splendor of twilight, Autumn colors and eager subjects. GR-HD1 video shot in Dallas on Thanksgiving Day.

Tom. Great quality. I assumed that you used the HD Capture Utility. My question(actually, cry for help) is what software did you use to convert the captured M2T file to WMV-HD?
DId you burn it into a DVD? If yes, which software?
thanks
Tom Roper
I use the HD-Capture utility that comes with the camera to copy the mpeg from the tape to the PC hard drive.
From there, I can immediately stream it right back out to the I-O Data AVeL LinkPlayer2 networked high definition DVD player with an ethernet cat5 cable. The native file plays in high definition on the HDTV monitor, without doing a thing! Instant Gratification!
To convert it to WMV-HD, I use TMPGEnc 3.0 Xpress, about $58. It's very simple to use. But there are all manner of other tools for making WMV-HD, including the free Microsoft encoder, Virtual Dub, AVISynth, Vegas, Ulead,...to name a few.
Tom Roper
To burn it to DVD, any burning app will do. I use Nero.
Tom Roper
Or did you mean, do I re-author it to a DVD disk at lowered resolution for distribution? Yes...if I'm giving it away. For that I use TMPGEnc DVD Author.
The process, is to use TMPGEnc 3.0 Xpress to convert the m2t to 720x480p30 NTSC-Video compatible mpeg2. And from there it goes into TMPGEnc DVD Author to convert the single mpeg file into the DVD compatible vobs, along with menus, chapters etc. DVD Author also will burn the DVD disk for you.
But if it's for me, I just burn the m2t file to DVD disk (up to about 38 minutes worth), and play it native on the LinkPlayer2.
I never use the camera or tape itself for playback.

Please keep this quiet. We don't want the word to leak out about just how good the HD1 is. Its great that the price is where it is about half the price of the obsolete VX2000 and DX100, and 1/3 the price of the mixed bag Sony FX1.

Thanks Tom. How much did you get the I-O Data AVeL LinkPlayer2 for? and where? :)
Tom Roper
You order it online, same day shipping from San Francisco.

Tom-
Thanks for all your Great Info. My JVC miniDV camcorder is dying and am ready to upgarde to the GR HD1, My question is to edit the HDV footage what is your work flow if WM9 is ur final output.
Also I want this just for the Family Camcorder I am not a PRO but I am quick study, do you think that I can use this cam for all life events?
Thanks

Hi Brian,
I use Womble Mpeg Video Wizard to edit directly onto the native m2t mpeg stream. It's fast, frame accurate, does cuts and joins, titling, voice overs, audio dubbing, background audio, transitions and effects. And it doesn't re-encode the video except around the transition points for a few frames on either side, so it's lossless.
That's all I do usually, since the I-O Data AVeL LinkPlayer2 (networked high-def DVD player) plays these files directly.
But if I need to reduce the file size to fit onto a single DVD disk, or want some chroma filters, I will use TMPGEnc 3.0 Xpress, and export to WMV9. Those files also play on the LinkPlayer2, and are virtually lossless compared to the original native stream.
Yes, I think it will do for all life events with aplomb, except low light.

Thanks Tom!
You bought yours on Ebay Correct? Did you Get a extended Warrenty with your Purchase or did you by a Second Party Warrenty or Non at all? Want of course to get the best deal I can (no Kidding right)!
As far as low Light , can you add a Light as with Other Camcorders and if so do you have a recomendation?
What filter/s at purchase would be a MUST?
My wife and I are expecting our second Child VERY soon May 19 so I need to act fast Here, The Light question becomes importants as I will be dealing with Low Light In Hospital Room and at house for a while.
Would it be possible to get a WMV Disk , I can view via PC using windows media player 10.
Thank again

- I purchased from a retailer, Ultimate Electronics, no extended warranty.
- It has a hot shoe (that's cold) for mounting a separate light, although I haven't.
- Must-have filters include 2x, 4x neutral density and a polarizer. Buy good quality filters, there is a difference.
- Email me for disk, motronix@vsdrives.com for WMV9 sample. I'll try and accommodate, but I'm leaving town on business soon.

Hello Tom, Douglas or any other JVC HDV owner.
I read a lot of what looks like uninformed criticism of this technology including several writers saying it is not an improvement on ordinary DV. Could one of you owners please do the classic standard scientific test = point your cam at an EIA1956 line resolution chart and tell us at what point the separate lines seem to merge into grey.
The chart is designed for 4:3 so for a valid result it needs to be framed edge to edge to get a horizontal resolution reading, with a separate shot framed top to bottom to get a vertical resolution reading.
Good DV-PALs I have tested (eg Sony 950) return 540 horizontal and 450 vertical.
EIA1956 and sample DV result to beat available at:

Iafilm,
Thanks for the test chart, I hope someone posts an HD1 result.
In general you can expect the HD1 to blow obsolete cameras like Sony950 out of the water on resolution. I think horizontal resolution will come in at 800 or 900 lines.
When posters criticize the HD1 it is not about resolution, but rather about the gray scale performance. Things like minimum sensitivity, signal-to-noise, and the selected tone curve (gamma), are what is critcized. The HD1/10 uses a 1/3" sensor, so sensitivity is not as good as cameras with larger sensors. And since each active element is only about 1/4 the size of comparable consumer cameras, sensitivity takes an additional hit. (Of course there are approximately 4X more sensors).
Signal-to-noise describes the dynamic range (12bits or 14bits), that characterizes how wide a range of light tones can be accomodated between black and white. The tone curve is criticized because you can't modify it in the camera-- so you either like what you get or you don't.
A further criticism is about mpeg compression artifacts that show up if the scene has a lot of fine detail and/or fast motion.
The results for average use are fantastic and blow away SD cameras.

Hi, I took a shot at the line resolution test.
See my images at www.sportsflashtech.com/video
Go down near the page bottom.
How do you read them?
Thanks!

Thanks very much for that!
> How do you read them?
I downloaded your .jpgs then viewed them in Microsoft Photo Editor. Important to make
sure that the quality of viewing method does not affect the result, so I zoom in
"200%" to look at the relevant parts of the charts.
For "left-right-2.jpg" I look at the vertical lines to judge Horizontal Res.
For "top-bot-2.jpg" I look at the horizontal lines to judge Vertical Res.
By my subjective judgement, which is however the same way I look
at charts from DV cams...
Horizontal Res = 760
Vertical Res = 510
Remember these are "line pairs" so this is indeed a significantly better result than
any DV camcorder is capable of.
In the PAL system which I use, a good DV result would be:
Horizotal Res = 540
Vertical Res = 400
Tom Roper
I hope someone can do this test. Unfortunately, I've taken on new job, broad responsibilities, and my time for this will be unfortunately be impacted... :(
That said, the stated specs on the JVC website calls for something like 690-700 horizontal tv lines resolution.
When resolution is the only factor, there is no argument that HDV exceeds DV. The arguments arise from other subjective impressions of the video output, mpeg compression, exposure latitude, gamma, panning performance.
Update:
I now see that Douglas, Richa and Iafilm have responded to the poster...Thanks! Seems like good consensus and correct interpretations.
