It is very common to see people confused about 4K Ultra HD and regular Blu-ray, especially considering that both are essentially Blu-ray Discs. Therefore, we will help you to better understand both 4K UHD and Blu-ray by comparing them. We will also show you how to rip 4K Ultra HD or HD movies to other digital formats, as well as how to play 4K Ultra HD movies on your PC or Mac computer.

Part 1: Comparison between 4K Ultra HD and Blu-ray

A UHD disc, or Ultra HD Blu-ray Disc are discs that are able to store ultra high-definition (UHD or 4K) content, as well as advanced surround sound (such as Dolby Atmos and DTS-X surround sound). While assumed to be the same as traditional Blu-ray media, UHD Blu-ray Discs are different in the way they are executed. In the most simplest terms, that means your traditional Blu-ray Player or your computer’s Blu-ray drive will need to be entirely replaced in order to support UHD Blu-ray Discs. UHD Blu-ray Discs will simply not work on Blu-ray drives, even though the discs are technically similar. Therefore, refer to the comparison table below to better understand 4K Ultra HD vs Blu-ray.

Ripping your 4K Ultra HD discs has been made possible and very easy, thanks to Leawo Blu-ray Ripper, the best 4K UHD Blu-ray Disc, regular Blu-ray Disc and DVD ripping software. It has the following features and advantages that should make you consider it for this task:

  • Leawo Blu-ray Ripper
  • Leawo Blu-ray Ripper

    ☉ Decrypt and rip Blu-ray/DVD discs with disc protection and region code
    ☉ Convert Blu-ray/DVD to MP4, MKV, AVI, MOV, FLV, and other 180+ HD/SD formats
    ☉ Convert Blu-ray/DVD main movie to videos for space saving
    ☉ Convert 2D Blu-ray/DVD movies to 3D movies with 6 different 3D effects
    ☉ Fast conversion with NVIDIA CUDA, AMD APP and Intel Quick Sync acceleration technologies

Versions for macOS and Windows operating systems are available for download. Once you have downloaded this software, follow the steps below for using it:

Step 1: Load the 4K UHD Blu-ray Disc

Insert the Blu-ray Disc into the drive (both copy protected and non-protected are supported), and then launch Leawo Prof. Media. Open the “Convert” module, and then click the "Add Blu-ray/DVD" button on the main interface.


Step 2: Select the output format

Click the drop-down list next to the “Add Photo” button. Select “Change” to enter the Profile settings panel where you can choose the output format from the “Format” group, for example HD MP4 VIDEO.


Note: You can click the same drop-down list and click the "Edit" button to adjust the video and audio parameters of the output files. They include video and audio codec, bit rate, aspect ratio, frame rate, channel, etc.


Step 3: Start ripping your 4K UHD Blu-ray Discs

Click the green “Convert” button and then set the output directory to save the final converted Blu-ray movies in the “Save to” box. Click the button again and the ripping should start. The ripped videos will be saved onto your hard drive in the format you chose.


Note: Before you rip your 4K Ultra HD Blu-ray Discs, you should first of all ensure that you have a 4K UHD optical drive, as regular Blu-ray drives cannot support this disc type. Second, you should also ensure that your 4K UHD optical drive is ‘friendly’. If your drive is ‘unfriendly’ (the type which implements AACS2 protection), this whole task will be impossible because the protection will prevent ripping or copying. What you will need to do in this case is to downgrade your UHD optical drive firmware with a tool such as Leawo UHD Drive Tool. This is a superb, yet flexible UHD drive tool that allows you to read, rip, or burn discs without any restrictions.

Part 3: How to Play 4K Ultra or HD Movies on PC/Mac

Playing your 4K Ultra movies on your Windows or Mac computer just got easier, thanks to Leawo Free Blu-ray Player one of the best 4K Ultra HD player. Why should you consider this media playback software? Have a look at its features and advantages:

  • Blu-ray-player

    Step 1: Load the 4K UHD content. Open Leawo Blu-ray Player, click the green "Open File" button to browse and load the videos for playback. Insert the corresponding DVD disc into the disc drive, or drag the file directly into the player. You will see the media on the playlist.

  • playback-setting

    Step 2: Set the playback options. There will be a bunch of custom features for you to use, including subtitles, audio output, snapshot, DVD Blu-ray and so on. Click the settings button to enter the window for these features.

  • play-the-movie

    Step 3: Enjoy the 4K UHD content. Click the start button to play the movie. You will be able to watch the most cinema-like movie streaming at home theater.

If you notice that your 4K Ultra HD Blu-ray movies cannot play on Leawo Blu-ray Player, it could probably be, because of your UHD Blu-ray drive. Basically, there are two types of UHD Blu-ray drives, that is the ‘friendly’ and ‘unfriendly’ drives. In this case, your drive could be ‘unfriendly’ (which implements the AACS2 protection, thereby blocking some Ultra HD Blu-ray Discs even for playback). The solution to fixing this problem is to downgrade your UHD Blu-ray drive firmware, and you can also use Leawo UHD Drive Tool for the task.
