Are 4K DVD players worth it? ›

If you have a 4K TV and you want to see its best picture, you'll want a 4K Blu-ray player. Ultra HD Blu-ray discs can hold much more data than standard Blu-ray discs, so they can deliver full 4K resolution along with enhanced color and contrast.

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 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.

If the disc you're playing isn't 4K, your blu-ray player will upscale it. That uses an algorithm to fill in the gaps between the quality of the source material and what a 4K version would be, and the best 4K players do a superb job of this.

Most Blu-ray discs have a resolution of 1920x1080. The resolution of 4K UHD is twice that of Blu-ray, which generally provides a better watching experience. 4K resolution offers greater clarity and more details, making the experience of watching a 4K movie DVD closer to what you would see in a theater.

It's a matter of pixels

When referring to the UHD, the industry rounded up the horizontal pixel count to 4000 pixels and it became popularly known as 4K. However, (!), it is different from native 4K which denotes an even larger horizontal resolution of 4096 pixels!

We just mentioned that an hour of 4K video uses about 45GB of storage space. Start with 63GB unless you are shooting way less than an hour or are not concerned about running out of space. Card capacities can range up to 256GB and are ideal for 4K video.

How much bandwidth does a 4K stream use? A 4K stream uses around 25 Mbps of bandwidth, which is much higher than standard or high-definition streams. For smooth streaming, a stable internet connection with at least 50 Mbps download speed is recommended.

While HD videos are large, a 4K video is about four times the resolution of standard HD and requires four times as much storage – just two to three minutes of uncompressed 4K film, or the length of a movie trailer, can be up to 500GB.

You can choose the frame rate according to your project's specific requirements. 4K 30fps works best for standard video content and offers high resolution and a cinematic look. On the other hand, 4K at 60fps provides smoother motion and is ideal for faster movements.

The highest 4K bitrate now averages around half of what it used to be (8Mbps rather than 16Mbps), but Netflix does encode highly complex 4K video at higher bitrates (even if they're higher than the previous 16Mbps).

High-resolution 4K video encodes at 2160p and has a bitrate between 44 and 56Mbps on a low frame rate and 65 to 85Mbps with a high frame rate. That higher quality footage will look great, but the level of quality and usability are often at odds with each other.

This is the most important takeaway you can get from this article. You need an Ultra HD Blu-ray player to play Ultra HD Blu-ray discs. If you put an Ultra HD Blu-ray disc in your current (non-Ultra HD) Blu-ray player, it won't work.

Yes, 4K Blu-ray players will also play standard Blu-ray discs and even DVDs.

“In terms of the dynamic range and compression, the 4K Blu-ray will always trump any streaming service out there,” Teoh says. You might not notice the difference from your TV's built-in speakers, he admits, but it should be apparent when played through any half-decent soundbar or AV receiver.

4K UHD video signals require a faster HDMI cable than HD or Standard-definition signals. High-speed HDMI cables are also necessary for taking advantage of the HDR (High Dynamic Range) technology built into 4K TVs and Blu-ray players.
