How to buy a high-quality Blu-ray disc?is what we are today.
1 Is there a difference in movie content?
We know a ** Blu-ray movie with compressed sound and picture quality. A regular Blu-ray disc provides higher** and audio quality, but generally only contains the movie itself. And a collector's edition Blu-ray disc, not only has high-quality feature films, but also can see some additional content that cannot be obtained from ** resources. For example, behind-the-scenes footage of the movie, director's commentary, and deleted scenes, etc., to provide the audience with a more in-depth movie experience.
Senior burners who like Blu-ray tend to prefer the collector's edition, which has a more exquisite design in addition to unique content.
2 Is the resolution greasy?
The resolution of Blu-ray movie discs is usually achieved according to the standards set by the specification, and most Blu-ray movie discs are rendered in 1080p resolution. However, there are also a lot of 2K and 4K Blu-ray discs nowadays. However, sometimes there are situations that can lead to misunderstandings about resolution, such as:
Resolution increase for special versions:Some special collector's editions or remastered editions may be available in higher resolution**, but this is not a feature available on all discs.
Advertised as 4k but actually 1080p:Some discs may advertise 4K resolution as advertised, but the actual ** content may still be 1080p. Such a situation may lead to misunderstandings among consumers about the resolution of the disc.
Upsample:Some Blu-ray discs may use upsampling techniques to improve image quality through some processing. While this processing may improve image detail, it doesn't equate to true 4K resolution.
3 Is the audio quality fake?
The audio quality of Blu-ray discs is usually achieved according to specific audio coding standards, such as Dolby TrueHD, DTS-HD Master Audio, etc. These standards provide high-fidelity audio coding that delivers a clear, rich audio experience. However, in some cases, there may be some misleading or exaggerated claims about the audio quality, which are usually due to the following reasons:
**Device Limitations:High-fidelity audio encoding requires a compatible ** device to restore and render. If you are using a device that doesn't support these audio codecs, you won't be able to experience high-quality audio. Therefore, it is especially important to choose a Blu-ray player with strong decoding ability.
