how come no one is making a HD video camera that uses DV tapes ?

[Onceler2]

but uses mpeg4 or h262 not mpeg 2 like the 1080i corders use ,getting full 1080p
I've been looking at the Panasonic HDC-SD5BNDL which captures to flash but uses mpeg4 (or h.262)and captures at true 1080p.
I have seen a few of the mpeg2 to DV camcorders and don't think that 1080i (which is what they capture at)is impressive at all
the Panasonic HDC-SD5BNDL would be ideal if only it captured to DV tape

[zoobie]

how about shooting direct to blu-ray?

I am leary of using any optical media as if it gets shaken you wind up with unusable video because the laser jumped and made a coaster

1080p HDV camcorders exist.

Panasonic HDC SD5 captures at 1080i on flash memory (SDHC cards). The capured files(AVC h.264) is highly compressed, allowing for the use of flash memory. MiniDV tape is used to capture less compressed video (MPG2) in HDV cam.

To get 1080p video on miniDV tape, one has to buy professional HDV cams

1080p HDV camcorders exist.

can you give me some examples please?

Some info on a Pro HD cam with 1080p, this one is based on an advanced AVC codec (AVC-Intra), not using tape but a P2 card

What is your goal for this video and budget?

Chasing "full 1080p" is not what you want in a camcorder. The best of the consumer-prosumer camcorders (regardless of recording format) can do 1440x1080p/24, 1280x720p/24,30 or 960x720p/24,30,60.

For recording format you usually want all I frames or the shortest GOP with least compression.

In that regard DV stands out for SD recording. For HD the classic all I frame formats are HDCAM and DVCProHD. The new tech h.264 solution is AVC-Intra. Below that you have in order of production quality*

XDCAM-HD (~15 frame GOP, MPeg2, 18-35Mb/s)
HDV (~15 frame GOP, MPeg2, 25 Mb/s)
AVCHD (~15 frame GOP, H.264, 8-15 Mb/s)

* production quality means that editing is expected. AVCHD can do high quality as a release format but suffers generation loss when edited or transcoded.

Have a look here.

The Sony HVR-V1U makes a 1440x1080p/24 output by interpolation much like the Canon HV20 does (but with higher def source sensors).

1440x1080 = 1.555 MPixels

This camera uses 3x 1.12 MPixel (gross not in frame) RGB CMOS sensors and filters Y to 1440x1080 using the normal pixel shift algorithms. The result is very good but not pixel by pixel. None of them are.

The broadcast industry long ago figured that bitrate trumps resolution when it comes to production image quality.

That is why expensive DVCProHD cameras (and AVC-Intra) filter down to 960x720 to get to 59.94p frame rates.

The home TV user is chasing a ghost worrying about 1920x1080p resolution at 19-25 Mb/s bit rates except for 24p BluRay discs and very large screens. In most cases a 1366x768 display will look just as good at normal viewing distance.

You must hate all the HD broadcasts then, which are all 1440x1080 or lower, at bitrates which don't give better quality than 25Mbps MPEG-2 HD.

The broadcasters are using cameras with superior optics and sensors, but format wise, the 25Mbps MPEG-2 1080i60 and 1080p24 available on something like the HV20 are good enough. I'd prefer 1080p60, but almost no one has that yet, and certainly not in a sub $1000 consumer camcorder!
