  1. I thought I'd be done by now with optical media stress tests. But Smartbuy BD-R and Ridata BD-R proved to be better than I thought. You never know about these things. Memorex BD-R proved to be one of the worst and you would think it would be among the best! I have to update the article, but addendum test results are here below. Here are previous BD-R stress tests. Blu-ray Discs …they are not all the same. – Daniel D. Teoli Jr. Archival Collection – II (home.blog) Memorex BD-R 25GB single layer 6x. Tested twice. Both tests failed within 30 days of sun. Smartbuy BD-R 25GB 1-6X. Passed 2 months of sun and tests are ongoing. Ridata BD-R 25GB 6x. Passed 2 months of sun and tests are ongoing. None of the BD-R I've tested have been interim champs. In other words, they die within a month of sun or will last a year of sun; so it will be interesting to see what these 2 discs can actually take. If you have Memorex BD-R, I would not use them for archival work. Personally, I use the remaining stock I have for temp work only. <><><><> Reel People Film ad 1983 Selection from Daniel D.

  2. Now, Perry will tell you upscaling loses sharpness. And that it does...if you use a microscope. I've done lots of upscaling with still photos. It has its use, but it not a magic bullet. https://danieldteolijrarchivalcollection.wordpress.com/2019/04/27/to-upscale-or-not-upscale/ But the question here is not how upscaling works for the pixel peepers, it is how does upscaling work in the real world for TV and the big screen when viewed at normal viewing distances. When I shot 'Offshoots...' I had to use a relatively low res camera. It produced a 1280x720 file. When I used higher res cameras I got too much moiré while shooting the tablet's screen. nsfw I made standard def DVD and Blu-ray 1080 of 'Offshoots...' The upscaled Blu-ray looked very good. Much, much nicer than the standard def DVD. I also made an upscaled file that was 3840x2160. When I burned a Blu-ray of it, the 3840x2160 looked basically the same as the 1920x1080 version on a 70 inch TV and I didn't see any benefit to it one way or the other, even when viewed a few feet from the screen. (I was mainly looking to see if it was less sharp and that is was not.) But my question is this... I don't have means to project it bigger. Has anyone upscaled for the big screen? Would there be any benefit in the 3840x2160 image over the 1920x1080 for projection on big screens? (And if you have not upscaled for the big screen, then what are you basing your opinion on?) Thanks
  3. How do I screen grab from a blu ray or DVD? Is there a certain program I have to use? I'm using the program DVD Player on my mac and the screen shot feature, Shift + Command + 3, but this feature doesn't capture the image that's on DVD Player.

  5. I have some questions about how Blu-ray Disc video differs from VOD available on various streaming services. What are the main differences between a Blu-ray video and a video from any of the streaming-services ones? What changes the most? Is it the amount of colours? Is contrast lower? How much less sharp are the streaming videos? Do the same differences apply whether it be 1080p HD content vs. Blu-ray or the 4K UHD Blu-rays and UHD streaming? Are there any differences in quality between various streaming services? Is the same film on, for example, Amazon Video in the same format and of the same quality as it is on Netflix? Are the codecs used by various streaming Web sites the same? For example, I see that Vimeo, YouTube, and iTunes Store use H.264. If both a Blu-ray Disc and a streaming service use H.264, why is streaming video of lower quality? I presume it’s because of the compression scheme. Are the compression schemes all the same on various VOD Web sites? So a single-layer Blu-ray Disc can contain up to 25 GB of data and the dual-layer one 50. If you were the download a 1080p streaming video, how much storage would it occupy? Is the problem with the difference in quality a problem of internet speeds or does it lie somewhere else? A Blu-ray Disc can have a bitrate of up to 40 Mbps. What are the bitrate of streaming services? What kind of speeds will you need for uninterrupted, smooth streaming of 4K UHD video? Or, more generally, how do you calculate the speed needed for a content with a particular resolotion, given that this will change a lot in the future? Will we eventually have even the true Blu-ray Disc audio experience in streaming, too? Will streaming services eventually replace Blu-ray Discs and what are some of the things that need to happen for that to occur? I forgot a lot of what I was going to ask, and one thread got lost when I accidentally shut down my browser, but I think I’ve managed to recover the gist of what I was going for.
  6. Just watched the new Criterion Blu-Ray Edition of Bergman's Persona and (as always) I am blown away at Sven's photography. Anyone know what stock that was shot on? It looks very much like 5231...
