Re: Need For Speed 2014 Bluray 720p Download
Dorthea Tingler
Hi,
I have a collection of ripped 4k Blurays from my collection. They are stored on a NAS and connected to my Apple TV via Ethernet. Local streaming ist all fine.
My family wants to access that library as well. They could add my NAS as a WebDAV server to their Infuse library and stream content.
My upload speed is 75 Mbit/s. From experience, would that be sufficient to stream 4k BDMVs? I know they frequently exceed the 75 Mbit, but I was hoping it could work with buffering and averaging.
Try it. In fact, in most cases, 100 megabits is enough. But some BluRay and remuxs have an inflated bitrate. They will sometimes pause for buffering.
If you do not have the opportunity to increase the Internet speed, you can pause the movie when you start and wait a few minutes for buffering. It might help.
When viewing files that you have downloaded, there will be no decrease in bitrate. There will just be a frequent stop of playback for buffering. Lowering the bitrate is possible only in online streaming (Apple, Netflix etc)
People here have had a hard enough time playing 4K rips locally over WiFi, let alone over the internet. Technically the 4K blu-ray spec maxes out at 144Mbps. Although average bitrate will help you figure out roughly what you need, there will be variable bitrates throughout the video that are higher. You also have to remember that if you pay for 100Mbps, you might not regularly get that (although sometimes things are higher). you will need to account for other devices using your network too and make sure only one person is streaming at a time. Also the other person must be using Ethernet as this would definitely not work if any portion of the system is on WiFi. There will always be a performance hit when using file servers. You will not get a 1:1 bitrate of file bits to internet bits. There is an overhead for translating it over a network.
You might consider setting up plex instead for that purpose which does cost money but might be less than increasing your internet speeds and allow for dropping quality with less buffering when needed.
I have a Lacie external BluRay burner connected to my Mac Pro via Firewire400. I'm running Snow Leopard. Using Toast and Final Cut to burn BluRay. My discs are 1-6x speed and the drive will handle speeds up to 12x.
The issue I am having is getting the MacPro and the OS to write at a speed highter than 1x. I have tried different burn methods and no matter what I do I cannot get the drive to burn over 1x on BluRay. DVD writing is just fine... only speed issue with BluRay.
I've contacted Lacie and done much troubleshooting to no avail. I have even had thm send me a new drive thinking it was a hardware issue. But even with the new drive, only 1x BluRay burn speeds are achieved.
I just got the same buner and am having the same problem. I have Verbatim 6x BD-R discs and am using Toast Titanium 11 with firewire. Every once in a while I see the current write speed flash from 1x to 2x back to 1x. I tried changing the write speed from "best" to 6x with no improvement. I found it interesting that this Lacie branded device shows up as a Pioneer BD-RW BDR-208M in Disk Utility.
If you discover a remedy please pass it on. I've replaced the drive thinking it was the drive and the problem still persists. Tries different software, same issue. I'm thinking of moving it to a windows based system to see what the burn speeds are there to compare.
I was on the phone with Lacie for a while today. While troubleshooting, we were able to get speeds that avereaged 3x while burning data, but only 1x while buring a video Blu-ray. Toast does all the converting before it starts burning, so we couldn't figure out why it was so much slower making a video disc. Also, it should burn faster than 3x for data. I have opened a support case with Roxio which was a nightmare. Waiting on a reply from them. I'll need to try to burn from Compressor and directly from Finder, then compare the results.
I'm curious on what your results will be. I really didn't achieve much better burn speeds on bluray from Compressor. I've times them both and the difference is negligible. Please report your findings when you can.
1. Is there any chance that these are RW discs? This may seem a dumb question since I don't even know if such things exist, but "regular" RW (re-writable) discs have always been IME waaaay slower than -R/+R discs.
2. How much free space do you have on your boot drive? I'm thinking that for a BR disc (which holds about 25GB full IIRC) you'd need 50-100GB free for temp space or more. Might even need to be contiguous free space, I don't know enough about BR burning to know.
Well, the system this drive is hooked up to is a well equipped system... lots of RAM and lots of hard drive space available (over 300gb). I have been using everything from DVD-RW to BD-R. Seems DVD's burn perfect - fast with no errors. Bluray is another story - burning a 2 hour BD-R can take a ridiculous amount of time between rendering and actual burning, with burning only writing at 1x - 2x speeds which is the issue at the drive is supposed to write at 12x speeds (which is the write speed for the BD-R discs I have).
We usually get well-priced Ridata bulk media that's sold as 4x or 6x but find that Toast rates them at 8x or 10x. To help ensure reliability, we're conservative with burn rates and normally burn at 4x, sometimes at 6x and have about 2% of the burned media that fails verification. We've often restored from blu-ray media that's many months old and have had no problems. A few times, I've restored from blu-ray media over a year old, also without problems. I've restored from DVD media that's over 5 years old, without issues (we nearly always used DVD-R+ media).
We've always used Pioneer external burners (including when we used to burn CDs then DVDs) in an Otherworld Computing case via FireWire (no, I'm not affiliated with Pioneer nor with OWC but have dealt with OWC for about 15 years). In our experience, the Pioneer burners are natively supported by OS X, are inexpensive and are also quite reliable -- we typically do 300-500 burns before replacing a unit, though we've not yet reached that point with the blu-ray burners. Currently we have 2 Pioneer blu-ray burner models; one BDR-206 and one BDR-208 and the backups are always burned on the newest model.
Don't be surprised that LaCie uses a Pioneer drive. LaCie repackages HDDs and Storage drives into their own cases. Actually, most brands are just names on a case. (except Seagate and WD which have their own drives in plastic, unfriendly cases). And that drive can handle up to 15x, not just 12x.
If you are using a MacPro (which model?), have you thought about putting in a BD burner direct into one of the optical drive bays? Make sure you have the correct model (Sata for Sata, Pata for Pata) otherwise you will need some kind of bridge/adaptor. That way, you isolate the LaCie Bridge, and Firewire from the picture.
Blu-ray (Blu-ray Disc or BD) is a digital optical disc data storage format designed to supersede the DVD format. It was invented and developed in 2005 and released worldwide on June 20, 2006, capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X. The name refers to the blue laser (actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
The BD format was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. Sony unveiled the first Blu-ray Disc prototypes in October 2000, and the first prototype player was released in Japan in April 2003. Afterward, it continued to be developed until its official worldwide release on June 20, 2006, beginning the high-definition optical disc format war, where Blu-ray Disc competed with the HD DVD format. Toshiba, the main company supporting HD DVD, conceded in February 2008,[9] and later released its own Blu-ray Disc player in late 2009.[10] According to Media Research, high-definition software sales in the United States were slower in the first two years than DVD software sales.[11] Blu-ray's competition includes video on demand (VOD) and DVD.[12] In January 2016, 44% of U.S. broadband households had a Blu-ray player.[13]
The information density of the DVD format was limited by the wavelength of the laser diodes used. Following protracted development, blue laser diodes operating at 405 nanometers became available on a production basis, allowing for development of a denser storage format that could hold higher-definition media, with prototype discs made with diodes at a slightly longer wavelength of 407 nanometers in October 1998.[14][15] Sony commenced two projects in collaboration with Panasonic, Philips, and TDK,[16] applying the new diodes: UDO (Ultra Density Optical),[17] and DVR Blue (together with Pioneer),[18] a format of rewritable discs that would eventually become Blu-ray Disc (more specifically, BD-RE). The core technologies of the formats are similar. The first DVR Blue prototypes were unveiled by Sony at the CEATEC exhibition in October 2000.[19] A trademark for the "Blue Disc" logo was filed on February 9, 2001.[20] On February 19, 2002, the project was officially announced as Blu-ray Disc,[21][22] and Blu-ray Disc Founders was founded by the nine initial members.
