If I want to shoot a music video with the new hvx using the 1080 mode and later convert it into 720 to burn the clip into a dvd media, will I get a better image quality than if I were to shoot in 720? ( forgive me for any grammar mistakes for English is not my mother tongue )
 
The only image quaity advantage would be cropping. You could reframe slightly or punch in a bit but the downresed image would be no better than just shooting 720P and you would loose your over/under crank ability. Probably better to just shoot 720P.
Save 1080 for your indy feature film.
 
Thanks evinsky! I thought I would end up with a better image quality because the 1080 resolution would allow me to keep a sharper image when converting into 720p. I´ve downloaded some videos which were shot in 1080 and I´ve made a test once converting them into 720 and the end result was better than I expected. The only problem was that I could not compare the results with 720 native videos.
 
i would say shoot 720.. remember, working with P2, if you shoot 720p its gonna give you alot more shooting time per card.
 
You don't have to wait for HD-DVD (which will take five or six years to reach any sort of critical mass in homes even if it's a hit... you know, JVC introduced D-VHS six years ago, and I'm sure they've probably sold at least a dozen D-VHS decks by now!)

You can author high-def DVDs today, and actually distribute them and customers can actually play them on their existing PCs. Not on their TVs, mind you, but on their computers. Panasonic's HVX Preview DVD has a high-definition version distributed on a regular DVD.

Speaking of HD-DVD/Blu-Ray, have you heard the latest about Sony's little disc-locking patent? According to someone on the Vegas board, Sony patented technology for a one-disc, one-player technique. Each disc can be encoded with a registration key. When you put the disc in the player, the player registers the disc to that machine and only that machine, and it destroys the key on the disc. So, what if you want to play your disc on your other player? You can't. What if you want to lend it to a friend? Can't. What if you want to rent a disc at Blockbuster for the evening? Can't. What if you want to sell your disc on ebay? Can't. What if your player breaks, or is stolen -- well, sorry, so sad, but your entire library is now worthless.

The article said only that Sony had been granted a patent for the technology, not that they intended to implement it in their blu-ray players (they may, they may not, that remains to be seen). There's all sorts of web articles saying that Sony may, or could, or won't, implement this disc-locking system on the PS3. Would they also try it with home blu-ray players? Since they use the same discs?

One can only hope that such consumer-unfriendly technology will die the same inglorious, horrific, and well-deserved death that the Circuit-City DIVX discs met, and Sony's rootkit fiasco (they've now been sued by the state of Texas over that nonsense) will knock some sense into them.

Unbelievable. But just because a patent has been granted doesn't mean a technology will be used, and for the single argument above alone surely, surely they aren't going to be so stupid? If they were, I suspect ordinary DVDs will have a much longer life span and HD will be put back years.
 
This is something me and Barry will never agree on , HD adoption.

5 or 6 years? are you nuts? Every major studio has signed on to one HD format and are prepared to release titles as soon as the players are public. DVD took 3 years to kill VHS.. and thats with studios holding out for the first 18months. As for Price, HD-DVD Players will be $800 when they come out, but I suspect by next christmas we will see them in the $300 to $400 price point. Someone remember this thread and lets check back here in a year. If Barry is right I will pay for him to goto driving school.

People want to watch HD.. look at the numbers on HD cable, its doing amazingly well. And to watch HD on cable you need to spend $300 on a HD cable box.. or $800 on one with a hard drive in it. HD-DVD will be rocking.

D-VHS is a joke, never was promoted properly and just had issues from the get go.

I just dont think the whole watching HD on the computer thing will fly. That said, My HD content on my desktop is pushed through a networked Buffalo HD Player out to my HD projector.. so it is possible to watch HD-DVD's on TV now.


Maybe you look at adoption different then me though.. maybe you mean every single television on the planet.


And that Sony thing is ridiculous.. its like those DVD's they made that would blow up after you exposed them to air.. i dont think anybody is gonna buy into that.
 
isn´t a similar locking code on the digital cinema distribution: a filmfile is sent with a code that matches one projector only. i guess it makes sense there. not in consumer world.

And what if the projector blows up? Would you have to buy another copy of the movie?
That sucks! And it doesn't work.
 
i hear the DARK SIDE is nice this time of year!!

I imagine that would fuel pirate hd-dvd / blue-ray sales and sony could endup shooting themselves in the foot, ie if you can get hold of hd disc that dosnt lock to one player thats a pirate ..i imagine a lot of people would choose that over an original that is locked.

i have approx 500 dvds and all are originals , but threaten me with discs that have that stupid lock system on ..and i could easily be swayed to the dark -side!!
 
It also makes sense when shopping film dailies for review on a production - I agree it doesn't make sense on the consumer world, but there's lots of use in the professional production world.

I also agree with Jarred - We will see content within 8-18 months and see the adoption rate rise fairly quickly once it hits the streets.

well, i mean theatrical beamers (worth € 170.000 each). when they blow up you got bigger problems than authorizing your license for the new Harry Pooter flic.

BTW, i also expect a quick adoption of HD-DVD (cheaper than blue-ray). they are creating a tremendous hype in Europe right now and everyone asks me if I shoot HD yet. they have no reply when I say "for what", but expect me to do HD anyway. therefore HVX hurry up....
 
I think DVD caught on faster than HD will. Everyone already had a 480 capable TV when DVD's hit. Most who have HD TV's already will jump on it, but for those that will have to buy a TV, a new player, and all their movies again...I suspect they will wait a while.

My reply to "for what" would be one or all of "futureproofing", "overseas sales" or "corporate closed circuit" (onto proprietry DVD HD media, suitable for local display onto an HDready screen).

But by and large the market momentum is building fast. I'm not sure if it's yet worth buying a new camera specifically because of HD - but am sure that nowadays if kit has to be replaced, it would be stupid to replace it with anything other than an HD capable product.
 
The US has already gone through that face of future proofing their content. Any person who has a stake in content that has syndication or future value will be shooting film or HD.
 
braw, i think you have a very valid point. as a former marketing director, one thing i can say for sure is that every market moves quickly when the change is dramatic and the cost is reasonable (that is not a total replace) but when the market is a small change for a big cost the market is much slower to convert. broadcast from 320 lines to 480 lines was a major improvement but more improved was digital vs analog. dvd HD upgrade will be hard for the average viewer to recognize, since dvd is so dramatically betterr than VHS or broadcast. but HD is hard to VISUALIZE/SEE by the average untrained eye, let alone, most won't take the time to LEARN. moreover, who wants to have to upgrade the whole system for what appears to be a 15-20% visual improvement. don't get me wrong, the difference is much greater than that, BUT the consumer only sees the lower level of improvement. need proof? how many ppl pay the additional $10/mo for HD reception and "the box"? not many by comparison to the cost to assemble the task and thus the reason for the "sloooooooooooow" number of HD channels.

just a former marketing perspective.

One example of this is the state of converting old television shows for HD viewing. Old shows shot on film have a long life ahead of them, as they can be transferred to HD, cleaned up and made "like new" again. Shows that were videotaped originally won't fare as well as the film ones, and won't have the future earning potential.

An interesting hybrid, and a real problem, are shows in the late '80's/90's that were shot on film, edited on tape with numerous VFX done at the video post phase. While the original image is on film, the edit and all effects was done in video post. No future proofing there, and the expense to re-edit and re-VFX will most likely keep them from ever having an HD future as anything other than an up-convert.

Think about the irony; "Star Trek, the Next Generation" will be resolution starved compared to an HD of the original 60's series which was cut and edited on film! You won't see clean HD versions of Xena, Hercules and countless other shows that have this same problem. Thankfully, most new VFX series are posting and doing VFX at HD resolution, setting the stage for extra market potential in syndication.
