4K UHD Blu-ray movies have more than 70GB of data that is stored on a BD100/XL disc. This enormous file size is due to the very high quality of the audio and 4K UHD Blu-ray movie. 4K UHD Blu-ray discs can be converted to an ISO file. There is a reason why we convert a 4K UHD Blu-ray disc to an ISO. Since the BD disc can’t last forever and few scratches on the shiny surface can make them unreadable. In this case, you’ll have to buy that Blu-ray movie again if you never ripped that disc.

So storing the 4K UHD Blu-ray movies as ISO is lot more safe and convenient rather than keeping the disc. In this article we will be briefly discussing DVDFab UHD Copy and teach you its main functions and show you how to burn a 4K UHD ISO to disc (blank BD25, BD50, or BD100).

A Brief Introduction to DVDFab UHD Copy

DVDFab UHD Copy as the name suggests is a 4K UHD Blu-ray copy software that you can use to copy a 4K Ultra HD Blu-ray disc to another blank disc, ISO, or a BD folder. DVDFab UHD Copy provides three main functions which are explained below in detail.

1. Full Disc:

If you choose this option then DVDFab UHD Copy will copy the entire disc either to a blank BD50/25, or to anISO file or to a folder with BD100 2160p quality. The Full Disc mode actually compresses the original BD100 disc content to fit in a BD50 or BD25 blank discs. The compression technology retains the 2160p quality and will fit in a BD50/25 disc.

You should be aware of this fact that BD-XL discs cost 10 times more than BD50 discs. So, it won’t be a nice idea to buy such expensive discs when you can get the same quality from BD50 discs at dirt cheap price. You should give credit to DVDFab UHD Copy for letting you save a lot of money on BD-XL discs.

2. Main Movie:

A 4K UHD Blu-ray disc may have many videos like sample shots, making of the film content, directors’ cut videos etc. So, you may want to skip these videos and just want to copy the main movie only. You can do this by simply selecting the ‘Main Movie’ option. DVDFab will automatically select the main movie and will skip the rest.  It is similar to the ‘Full Disc’ function, the main movie function actually compresses the BD100 2160p content to fit on a BD50/25 disc while retaining the 2160p quality. Here you don’t need to spend money on expensive BD-XL/100 discs and can get the job done with cheaper discs while retaining the 2160p quality.Of course, the mode can alsocopy a 4K Ultra HD Blu-ray to anISO file or to a folder with BD100 2160p quality.

3. Clone/Burn

If you just simply want to clone or burn your 4K UHD Blu-ray disc in a 1:1 lossless ratio then go with this option. The clone option can only clone a disc to an ISO file.

So, these were the three main functions provided by DVDFab UHD Copy. I hope you got the details correctly.


How to Burn 4K UHD ISO to Disc?

I already told you that BD-XL is 10 times expensive than a regular BD50. So, it is not reasonable to buy a BD-XL for every disc burning task. Use the cheaper BD50 discs and get the same UHD experience as you would have gotten from a BD100 or XL disc. Don’t forget that DVDFab UHD Copy (also can be used as a blu-ray burner on mac) is the magician here which is doing the magic. So, let’s check the requirements below for this task.
