Why DVD9 dual layer media for Hollywood, but not consumers?
I've caught a few myths being repeated by our own members! :eek:
For shame! Shame, shame.... :o :p Don't worry, I'll be nice to you guys. (I save my scorn for those who profess to be experts or professionals on these topics, and then can't even demonstrate basic knowledge.) Anyway, I just felt the need to clear up some of what I was reading today: Quote:

Therefore, while it may be a DVD9, it's not necessary to achieve the quality found on those discs. A DVD5 would have been fine. You'll find many commercial releases, which lack fancy menus and bonus content, are on DVD5. Quote:
Want some DVD+R DL media? Get these: Verbatim (Mitsubishi) DVD+R DL from Amazon Quote:

i.e., Scanned film vs VHS tape (or even that "crystal clear" satellite signal) i.e., Hardware MPEG cards (Matrox, Sonic), or pro-line software encoders (MainConcept, Procoder) vs cheap consumer gear/software There's also something to be said for filter/clean-up work in the NLE, during pre-encode edits and distribution prep.

Remember that many studios get pissy about those unwatchable low-res videos you find on Youtube or torrents -- crap that no sane person would punish themselves to watch, yet studios feel threatened by a fuzzy/blocky 2-minute clip. Between that and the original Betamax case, it's pretty safe to safe that "they" don't want anybody to have any recordings of any kind. (Which the laws thankfully DO NOT agree with to date.) Quote:
Just remember that the same bitrates may not be good enough if your source isn't the same quality as theirs. Until next myth.... :) |
Not really sure what you mean by myths.
Why can't they just sell us DVD recorders to make perfect copies of things..... Guess what I was trying to say: Kind of hard speaking to a bloody computer... If you record something with low bit-rates u are going to get heavy macro blocking in the picture. Your standard Hollywood DVD is not using the same bit-rates if you recorded something on your DVD recorder in 2 hour mode. DVD recorders are not big in the USA, cause of the DVR's.... They never really took off, in best buy they may have like 4 machines at most on display for sale.... They have a lot of TiVo's Lord Smurf, you have even said yourself that these machines have gone backwards.... HD recorders, I think they may be out in the USA, but can't do HDMI inputs.... Normally I find a good 2 hour recording done by a good Hollywood company is around 5 + gigs. (((That is from ripping DVD's))) You have no idea how many problems I see in 2 hour VHS to DVD recordings in SP mode done on a crapy recorder... But the person recording doesn't know it is a crapy cause they don't know anything else.... Now your DVD recorder comes in 2 hour mode, so you are going to use that and not the 1 hour xp mode. That is assuming you have no insight at all to recording things....99.9% of people who use DVD recorders.... You may record to a Duel Layers disk in SP mode and get 3 hours and 40 minutes....Not 2 hours......... Hence the problem with not getting the best possible quality out of your DVD recorder...... You have been fooled already thinking 2 hour mode is good. They don't really explain FR recordings to you... 1 hour and 30 minutes is kind of the cut off on a normal single layer disk. For ok Marco Blocking That was the point I was trying to make.... I did digital tests of frames the other day in SP, FR 80 and XP mode...These were all digital recordings...You can really see a difference in the compression (what is a better word) I don't know... What I saw was a lot more bleeding of image in SP were in XP mode it was kind of clean..... Yea some of these Professional DVD's, do have Marco Blocking in the videos. A lot more than u would think also have audio & video out of sync. Most of the professional VHS to DVD shops as spoken about in the other post issue their DVD's to 2 hour mode...... Maybe that is the simple question to start with, how much information of recoding time can you put on a DVD....Normally they will say 2 hours..... Yea I still use 2 hour mode for digital recordings...sometimes...For VHS stuff, never the macro blocking is out of control bad...... If you are going to pay a shop to convert your VHS stuff, don't let them record or issue in 2 hour SP mode..... |

From how I read the other posts, it came across as if there was no way to create a DVD9 like "Hollywood" does, which seemed a bit .... I don't know .... off. Technically you can burn a dual-layer DVD+R DL (DVD9), although there are valid points to be made about source quality. For those who shoot their own DV home movies, using a good camera and good technique (tripod, steadycam, microphones, etc), then there's no reason their homemade DVDs can't be as good as something pressed and sold in a fancy case at the local Best Buy or Walmart. Most of your points here are "spot on". Very astute and accurate observations. Quote:

And the person, who you'd swear should have some ounce of intelligence and is clearly not blind, actually thinks this soft + blurry, noisy (chroma + grain), vibrating/shaky picture is "good" or "good enough" (a phrase that roughly translates to "I know it's crap but I refuse to acknowledge it").

While many of us do use DVD recorders for certain projects, because of the features unique to those units, few professionals (none?) ever use the term "mode" when discussing the project. We talk in terms of bitrates, bandwidth, resolutions, etc -- not these fake "modes" on a DVD recorder. Quote:
.................................................. ........... Talking with fellow TV hobbyists is fun. Granted, we're "preaching to the choir" here, between ourselves. But seeing how this is a public conversation, others will hopefully learn from our discourse. That's why I even bother to participate anywhere online. I can discuss stuff with others, and then it's available for others to learn from. Good stuff. :) |
