Author Topic: Let the HD DVD format wars begin... Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 10-06-2004 09:12 PM                    How visibly lossy is WMV-9 when used to put feature length material into a conventional DVD/R? I have the Terminator 2 disk but haven't tried it yet and obviously would not have a new technology disk to compare against. My limited tests projecting clips downloaded from the MS site looked pretty good, I thought.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 10-06-2004 10:00 PM                     WMV-9 looks pretty darn good projected on a 3 chip DLP considering how absurdely compressed it is. However you don't want to get too close to the screen!  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 10-11-2004 10:49 PM                        quote: WMV-9 looks pretty darn good projected on a 3 chip DLP considering how absurdely compressed it is. However you don't want to get too close to the screen! I was distracted by the compression artifacts when it was shown at ShoWest (clips from "Beat the Devil" and other films in the BMW series). Don't sit too close, and you might be satisfied.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 10-12-2004 01:14 AM                        What kind of compression artifacts were these? I find compression artifacts very distracting from any distance, as artifacting almost always results in overall loss of resolution. Compression should not be used on theatrical presentations in my opinion, and should be used only moderately on Blu-Ray DVD. With the cost of storage going down, I can't think of an argument FOR compression in theaters.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 10-12-2004 10:55 AM                        I recall mostly blockiness, and some temporal artifacts. Contouring artifacts also were noticable in uniform density areas like skies.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 10-12-2004 05:18 PM                        What are temporal artifacts? Is that where one part of the picture advances but another part does not?  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 10-12-2004 05:58 PM                  (AFAIK, for me): It means the frame data update rate is less than the frame/field refresh rate and as such the moving objects will "ghost" along the path of the object's motion. >>> Phil  |  IP: Logged Bobby Henderson "Ask me about Trajan."

Much of it comes down to the rate sustained data transfer for the playback device. A disc based medium like BluRay would probably not be able to play a mildly compressed HD video stream. I certainly don't expect it to match data transfer rates of HD digital video tape or high speed hard disc systems.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 10-13-2004 11:52 PM                        Is Phil's definition of temporal artifacting what you meant by the term, John?  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 10-14-2004 06:55 PM                        I usually notice any "stutter" in the action, not just the "ghosting". Although film can have "motion blur" and "strobing", the action is usually rendered smoothly.  |  IP: Logged Phil Blake Jedi Master Film Handler Posts: 558 From: esperance western australia Registered: Nov 2003 posted 10-15-2004 10:23 AM                        I wonder where It will stop , if it ever will. As a kid I collected movies on super 8mm , which had progressed from standard 8 , then I went on to collecting on Betamax video , which fell to VHS , I then collected on laser disc which has now fallen to DVD , my collecting reluctantly continues on DVD , while wondering where It will go next, having read this , I now know. Maybe the studios just like making lots of $$$ out of selling the same movie a thousand times over on many different formats .  |  IP: Logged Adam Wilbert Jedi Master Film Handler Posts: 590 From: Bellingham, WA, USA Registered: Mar 2002 posted 10-15-2004 01:37 PM                        ... or maybe technology helps the movie look and sound better than it did before. While I won't deny the perk of selling the same essential product over again, if that were the true motivation, there would be a ton of intervening steps, instead of the relatively large technological leaps. Only people who strive for the best presentation possible need to replace their collection. Phil, if you're really concerned with keeping up with better formats, just jump straight to the end and purchase 35mm prints!  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 10-15-2004 05:41 PM                        After HDTV there is something called "Ultra-High Definition" or some such nonsense. It offers up to 4000p of resolution. Dead serious.  |  IP: Logged Liam Utley Film Handler Posts: 42 From: Australia Registered: Oct 2003 posted 10-19-2004 07:57 AM                    In that case i'll skip buying a BD or HD DVD player and wait another year for the UHD DVD player. I'm one of those suckers that buys superbit DVD's despite my better judgement.  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 10-19-2004 04:07 PM                     Here's another thing which demands that you be careful when buying a HDTV set. According to a news story on CNN's website yesterday, some fellow with a Toshiba brand plasma TV suddenly had a bunch of cops and fireman running into his house looking for someone to rescue. His plasma screen TV was emitting a signal that a satellite picked up and interpreted as a distress signal. The frequency band emitted by the TV set is usually only used by boats. It is a mystery how the TV set was able to put out a signal strong enough that a satellite in orbit could receive it. The TV set owner was ordered to keep the thing turned off or face a $10,000 fine. Toshiba is reportedly replacing the guy's TV with a new model free of charge, sans the distress signal.  |  IP: Logged
