Conventional (or "pre-BD-XL") Blu-ray Discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives.
A 4K 30 fps 2-hour movie averages 14 GB in file size. (30 fps is the standard frame rate for most movies in the United States.) A 1080p HD 60 fps 2-hour movie averages 6 GB in file size.
A standard definition (SD) movie that you download to your device for streaming tends to be between 1 GB and 2 GBs, while high definition (HD) videos are twice that, ranging from 2 to 4 Gigabytes. And those sizes only encompass the final film.
The bit rate which depends on the video and audio codecs used, the resolution, the video/image quality, and compression. For decent quality 720p movies you could expect an average of roughly 800MB per movie. A 1TB Drive could hold over 1200 movies.
Based on high quality 1080p resolution or shorter 4K clips, if the average size of each movie is 4GB, then 1TB can hold approximately 250 movies. For longer, high-quality 4K clips, if the average size of each clip is 10GB, then 1TB can hold approximately 100 videos.
A single-layer Blu-ray disc can hold 25 GB worth of data, compared to 4.5 on a standard DVD. A dual layer BD disc holds up to 50 GB. This translates into the ability to store a full 1080p HD image.
Regarding how much storage is on a DVD, the capacity of the DVD and the bitrate of the video are two factors that affect how many videos you can save. A single-layer DVD typically has 4.7 GB. Double-layer DVDs usually have a storage capacity of 9.4 GB, while specific DVD formats can hold up to 15.9 GB.
Generally, an uncompressed 1080P video for two hours has a size of nearly 8TB. After compression, the Blu-ray video can reach about 30G, and ordinary quality video can reach about 5G. This is just the final release video size.
A typical Blu-ray movie usually ranges from 15GB to 30GB in size, with 4K UHD Blu-rays being around 50GB or more. That's a lot of space, and it's easy to fill up your hard drive after ripping only a small portion of your collection.
If you are watching a standard-definition stream, you can expect to use 1-2 GB per hour. And if you are watching an HD stream on a 4K TV, you can expect to use 7-10 GB per hour. The size of the screen is going to have a moderate impact on how much data you use.
UHD (4K) can average between 6-7 GB per hour. Apple TV: SD (480p) uses approximately 0.7 GB per hour, HD (720p) uses up to 2.5 GB per hour, HD (1080p) uses up to 3 GB per hour, and UHD (4K) uses about 8 GB per hour. YouTube: The recommended speed minimum for SD is 1.1 Mbps.
Add to that, you can stream just about any movie or show that you want so long as you subscribe to a streaming service like Netflix or Hulu, or you're willing to rent or buy it on-demand from your cable provider. However, a lot of people are actually still buying Blu-ray discs.
A Blu-ray player ensures movie nights won't be thwarted by problems with your network or service provider. Picture quality - Standard Blu-ray players deliver Blu-ray discs in 1080p resolution. Since they don't require compression, discs can deliver a better picture than standard HD streaming services.
Despite the name, neither the media nor the data is damaged after extraction. Ripping is often used to shift formats, and to edit, duplicate or back up media content.
Typically, downloaded standard definition Digital Movie files take up approximately 1-2 Gigabytes of space, and high definition files can take up to 2-4 GB.
A single-layer Blu-ray holds 25 gigabytes (GB), and a dual-layer Blu-ray (one with two layers of information, one on top of the other) holds 50 GB. By contrast, a single-layer DVD holds only 4.7 GB.
Disc capacities are 25 GB for single-layer discs, 50 GB for double-layer discs, 100 GB ("XL") for triple-layer, and 128 GB for quadruple-layer (in BD-R only).
A single-layer Blu-ray Disc can hold up to 25 GB, or 25000 MB. Dual-layer Blu-ray Discs can contain exactly twice that, 50 GB, or 50000 MB. BD-XL discs can contain 66 GB, 100 GB, or 128 GB (currently only available as a BD-R), depending on whether it has 2, 3 or 4 layers.
On average, a 25GB Blu-ray disc can hold 135 minutes of HD video using MPEG-2 compression format plus 2 hours of bonus material in standard definition quality or 10 hours of standard definition video. A 50GB Blu-ray disc can store approximately 3 hours of HD video plus 9 hours of standard definition bonus material.
The storage capacity of 4K UHD discs ranges from 66GB to 100GB. Blu-ray discs are also with single and double layers that allow them to store data from 25GB to 50GB.
Using Rayburn's number, in a single month you'd have to stream 416 Netflix videos of 90 minutes each to hit a 1TB data cap. Got four people in your family? You'd each need to watch 104 videos per month, or more than five hours of Netflix every day.
