Part 1: DVDFab UHD Creator: Quick Intro and Download Links

As the name suggests, DVDFab UHD Creator is a 4K UHD Blu-ray creating software which can create/burn an UHD Blu-ray disc, ISO, or an UHD folder from multiple videos having different formats. The DVDFab UHD Creator can also preserve HDR, HDR10, and Dolby Vision data while creating an 4K UHD Blu-ray. It can create four types of 4K UHD Blu-rays (BD25, BD50, BD66, and BD100). The converted videos will have 2160p resolution which is 4K resolution. Each of disc type can be burned to its corresponding blank Blu-ray disc and you can also choose to save the 4K UHD Blu-ray as an ISO or a folder.

An UHD ISO or a folder is an exact soft-copy of a 4K UHD Blu-ray disc. When you save the entire 4K UHD Blu-ray disc contents as it is in an image file then it is known as an disc ISO image file. This ISO file has everything same as that of the original disc. You can store this ISO file on your computer and can burn to a blank disc anytime. Just like an ISO, an UHD folder is an exact copy of the UHD Blu-ray disc. For making UHD ISOs and folder you’ll need special software like DVDFab 11 which can also remove Blu-ray protections before making an ISO or a folder. Please find the download link to DVDFab 11 below.

Step 3: Start to Burn MP4/MKV to UHD Blu-ray

Now you are just ready to start burning your videos to 4K UHD format. For doing this you have three options.

Each of these options is discussed below.

Start to burn mp4/mkv to UHD Blu-rays

Option #1: Burn a Blu-ray Disc

To burn a physical Blu-ray disc first get the right type of a blank Blu-ray disc. Head over to the ‘Advanced Settings’ and check which ‘Output’ you have selected. If suppose you have selected ‘BD50 2160p’ there then you’ll need a blank BD50 disc for burning. We suggest you using the output disc type wisely. Most of your projects will definitely come under BD25 only having 25GB storage capacity. So, only choose BD50 or higher Blu-ray type when your videos outsize the BD25 storage capacity.

Now after getting the right type of the Blu-ray disc, click the ‘Save to’ location field in DVDFab 11 and select your Blu-ray burner optical drive. Hit the ‘Start’ button and insert the blank Blu-ray disc when prompted. Wait until DVDFab finishes burning the Blu-ray disc for you.

Note: DVDFab 11 has its own Blu-ray burning engine so you don’t worry about looking for other third-party 4K UHD Blu-ray burners. This burning engine is capable enough to produce 4K UHDs without any reading errors. However, DVDFab 11 also supports ‘ImgBurn’ as a third-party disc burner. You can find this in ‘Common Settings>Drives>Blu-ray Write’.

Option #2: Convert and Save The Videos As An UHD ISO

If you don’t have a Blu-ray burner optical drive ROM then you can easily convert and save your videos as an UHD ISO file. This ISO image can be burned to a physical Blu-ray disc any time. It can also be played directly on various media players and can be stored on your computer’s hard drive. Click the ‘ISO’ button and select the output location then click the ‘Start’ button to start creating the UHD ISO.

Option #3: Convert and Save The Videos As A UHD Folder

It has the same properties as that of an UHD ISO. It also serves as the soft-copy of a UHD Blu-ray. Will have the same quality as that of a UHD Blu-ray disc or ISO. Simply click the ‘Folder’ icon as shown in the image above and select the output save location then hit the ‘Start’ button for creating the UHD folder.

When the conversion process completes you can enjoy your UHD Blu-ray disc, ISO, or folder. UHD ISOs and folders can be played on most compatible devices, these devices can be a PC, UHDTVs etc. Not all devices support playing ISO or folder files directly. Once done, you can watch your converted UHD Blu-ray with the best 4K media player, DVDFab Player.
