MOVIE BUFFS love to watch films more than once, so they are very active in collecting venerable DVDs to build or enrich their DVD libraries. But with the advent of the digital age, people tend to move media all over the place, to a local computer hard drive, central location, or cloud service, to name just a few.

ISO image, an uncompressed archive file of the physical optical disc, is one of the top choices in cutting the cord. If copying DVD to ISO image comes for safeguarding and managing DVD contents better, then converting DVD ISO Image to MP4 can be done either by a dvd ripper or video converter.

Why do People Want to Convert the ISO Image File to MP4?

1. Smaller File Size

If you do a 1:1 copy of a physical DVD using a DVD copier, the file size will be the same as the original disc. ISO image perfectly preserves all usable data (files and folders included) on the original DVD sector by sector and takes a similar file size with a DVD disc.

An average DVD ISO file has a size of about 5 – 8 GB. If you change the .iso to .mp4 format with the almost same quality, the file size is just less than 1 GB. So, clearly just by changing the file format but the file size reduces drastically.

2. Better Compatibility

ISO Image large files have bad compatibility with smart personal and home entertainment devices, for instance, they cannot be played directly on TVs, iOS/Android/Windows mobiles, and streaming services like Plex and game consoles.

MP4 file is already famous and can be playable on computers as well as smartphones and gadgets. That’s the main reason movie collectors choose to convert ISO to MP4 out of habit for watching everywhere or just freeing up limited space.

Steps to Convert ISO to MP4 Using a DVD Ripper

In all probability, a DVD ripper does have support for ISO disc image, and WinX DVD Ripper Platinum is a good option to choose from. In this article, we present you with a manual to help turn your ISO image of movies, TV series, workout, and music types into MP4 in clicks.

Step 1: Open the WinX DVD Ripper Platinum and Load ISO Image

Firstly, you can download WinX DVD ripper platinum to your Windows PC and follow the prompts to finish the installation on the computer. Every time you wish to turn an ISO image into an MP4 video, just adapt the instruction below. 

After launching the WinX DVD Ripper Platinum, you will see the following screen:

Click the “ISO Image” icon to browse and select the source DVD ISO image from the computer DVD drive. WinX DVD Ripper Platinum supports many file systems inside DVD discs and ISO Image, including widely used ISO 9660 and UDF.

Also, if your ISO contains region code, CSS, or any other types of copyright protections, it will automatically strip it in this loading process, picking the right title out for you if there’re multiple titles due to some encryption tech.

Note that you don’t have to switch “Auto Detect” to “Force UDF” or “Force ISO” unless the program fails to read your .iso file or you really know about the system type of ISO.


Step 2: Choose “MP4 Video” from the Output Profile List

MP4 is just a container format and may have different video & audio codec combinations. WinX DVD Ripper Platinum offers four MP4 options as an output format:

– Standard MP4 (h.264 + aac) & MPEG4 (mpeg4 + mp3) under “General Profiles” category

– AVC MP4 (h.264 + aac) & MP4 (mpeg4 + aac) under “PC General” category.

We can’t tell which one is the best, but we can figure out from countless user feedback that MP4 H.264 is the go-to pick for DVD ripping.

You also can choose the MP4 format for your portable devices, like MP4 format for Android under “Android Mobile” or MP4 format for iPhone under “Apple Device”. Click the OK button when finished.

Step 3: Custom Subtitle, Audio Channel, etc. on Demand & Choose Destination Folder

This step is optional.

ISO image file keeps all video, audio, and subtitle data on the original DVD disc. But MP4 can only reserve one audio track and one subtitle track. So you are enabled to access and do the selection.

On top of that, you can disable the subtitle or add any external .srt into a movie video, change video resolution/aspect ratio, trim/cut video content and merge a batch of titles into a single MP4 file. 

At the bottom of the screen, you can click the Destination Folder: Browse button to choose the destination to store the converted files.

Step 4: Start Converting DVD ISO to MP4 Format

Just above the Run button, there are several options that you can choose:

Hardware acceleration makes video processing faster while maintaining the highest possible quality by working together with WinX-unique “High Quality Engine” and “Deinterlacing”.

Enabling the “CPU Core Use” and “Hardware Accelerator” box harnesses the power of Intel® QSV and NVIDIA® NVENC/CUDA to boost the real-time performance for ISO to MP4 transcoding and all video editing missions faster than ever.

Here’s a real and overwhelming test on converting DVD to MP4 format, and ISO to MP4 would share the same result theoretically:

  • DVD for test: a new DVD release in 2018; size: 7.16GB; length: 1:32:12
  • PC for test: Windows 10 (64 bit); Intel(R) Core(TM) i5-3470; Nvidia GeForce GTX 750
  • Time & Speed: 23 minutes in total with 300 fps.

Drawing from the user guide above, you will know about how a well-rounded ISO Image converter works from start to finish. Not all software transforms ISO image to MP4 smoothly as WinX DVD Ripper Platinum does.

This is because some fail in defeating copy protection, some lose the efficiency game due to the lack of hardware acceleration support, or only embracing certain graphic cards (e.g. HandBrake + Intel QSV), and some sacrifice the video quality greatly to achieve the inane fast speed.
