1920 or 1440
Posted by Justin Heaney on November 4, 2008 at 10:48 pmHi there
I hope this is the right question for this forum.
Is HDV actually 1440 by 1080 anamorphic, stretched to give us 1920 by 1080?
If so, how can this be acceptable HD?It reminds me of when SD cameras would cheat us on stretching and squeezing images.
Does this shortcut also affect Panasonics P2 cameras using the DVCPROHD codecs, and XDcam?? or are they full raster?
Are there any forms of HD available (in the prosumer range) that give us full raster 1920 by 1080, and is it even necessary, or is the quality gain only marginal?Thanks
Justin

See above.

Prosumer and full raster? Not likely.

Yes.
[Justin Heaney] “If so, how can this be acceptable HD?”
HDV and DVCProHD are superbly engineered and widely used anamorphic formats that have helped to democratize HD production and post by giving us affordable, high quality compressed video formats that can be played back and edited off of affordable hard drive arrays. They are acceptable because they are good enough for a large number of video production and television applications and because they are considerably better than most SD.

Sure, check out the Sony EX1. It’s listed by Sony as a professional camera, but it’s only slightly more expensive than Sony’s prosumer cameras.

Dave,
At one time I agreed with you. I do an awful lot of HDV production and post now and I have come to think of it as a terrific gift. If handled properly HDV can look like a million bucks.

November 4, 2008 at 11:26 pmA lot of capture codecs use anamorphic. In my opinion, the biggest factor is not raster size but lens resolution. I have seen soggy HDCam and brilliant HDV.
Presuming a codec like HDV has poor resolution is silly. Three of the four docos nominated for best cinematography at this years AFI (Australian Film Institute awards) are HDV or XDCam. I am betting the one shot on HDV (and graded by me) will win because it is pin sharp, well lit & shot (Sony V1U). The next best looking was shot XDCam (35M/bs). Ironically the Panasonic one looks poorest, but again I suspect lens & filters to be the factor.

Yep Michael, I too have seen a lot of soft material in DVCProHD format, but I attribute it to the HVX200’s native 720p, often blown up to 1080i.
I always capture HDV as ProRes and have been very pleased with the results.

I actually prefer tape and HDV for most things. Some people like the P2 alternative. Go figure…

Thats because HVX sensor is 960×540.
They use interpolation to first uprez to 1080 then back down to 720
for the 720 mode.For that alone I’ve never used or been a fan of the HVX series.
I have an HD100 I use when needed for occasional shooting work and the
full raster 1280×720 progressive images that come out of it are
fantastic….https://hdcuisine.com/food_highlights.html -

Absolutely. The quality of the final image is all in the hands of the photographer. We’ve done multiple documentaries shot with HDV that are visually stunning.

Sounds like the old adage of “craft & lighting” wins through.HDV is a well thought out format it seems.
All the best

Check out Sony EX-3. It is a nice camera that shoots 1920×1080 with the larger 2/3 inch chip. It is in the higher end of the prosumer camera range.
