I have ripped all my movies to ISO image and now I want to compress and convert these ISO images to MP4 and watch them on my 4K TV. I will be using a desktop as a Plex server and passing through to Xbox One to watch to my TV.

DVD ISO image file is an archive file of an optical disc. It is big in size and not compatible with mobile devices and some popular programs such as Plex and Emby. So we need to convert ISO to MP4 to make our movies easy to store and play. This tutorial will show you how to turn ISO image to MP4 format quickly and easily on PC and Mac with WinX DVD Ripper, HandBrake, VLC, FFmpeg, MakeMKV, and an online tool.

Convert ISO to MP4

Why Do Users Choose to Convert ISO to MP4?

1. Compress movie size.

ISO Image contains everything written to a disc and is uncompressed. Thus, an ISO image file is only slightly smaller than a raw disc of data. An average 90-minute DVD ISO file has a size about 5 - 7.9 Gigabytes. While after we changed the .iso file to .mp4 with almost the same high quality, the size is around 0.8 - 0.9 Gigabyte. So it reduces the data infomration by approximately 80% without any image loss visually using WinX DVD Ripper.

2. Get easier access to play.

Similar to DVD disc, ISO image files are often large and can't be played directly on most mobile devices. While MP4 is fully supported by Android mobiles, iPhone iPads, TVs, game consoles, to name a few. That's one of the reasons why users want to convert ISO disk image file to MP4 - for more convenient playback.

Next, we'll introduce 6 ways to convert ISO to MP4.

Method 4. Convert ISO to MP4 with FFmpeg

There's curiosity among users about whether FFmpeg can convert ISO files to MP4. The answer is yes, it can. However, the process isn't as straightforward as just other ISO to MP4 converters. You need to mount the ISO file first.

Now, let's walk through the steps to convert ISO to MP4 with FFmpeg.

Step 1. Mount the ISO file.

Before converting ISO to MP4, you need to mount the ISO file to access its contents. This step is necessary to extract the video file contained within the ISO. To mount the ISO file, use the following command:

mkdir /mnt/iso
sudo mount -o loop /path/to/your/file.iso /mnt/iso

Replace /path/to/your/file.iso with the path to your ISO file.

Step 2. Locate the video file.

Navigate through the mounted ISO to find the video file you want to convert. Typically, video files within ISOs are found in directories like VIDEO_TS.

Step 3. Conversion with FFmpeg.

Once you've located the video file (e.g., a .VOB file), use FFmpeg to convert it to MP4 format. Execute the following command:

ffmpeg -i /mnt/iso/VIDEO_TS/video_file.vob -c:v libx264 -c:a aac -strict -2 output.mp4

Replace /mnt/iso/VIDEO_TS/video_file.vob with the actual path to your video file within the mounted ISO. The -c:v libx264 option specifies the H.264 video codec, and -c:a aac specifies the AAC audio codec. Adjust these options according to your preferences.

Then, FFmpeg will begin converting the video file to MP4 format. The conversion time depends on the size and complexity of the video. Once the conversion is complete, you'll find the converted MP4 file named output.mp4 in your current directory.

Tips: After conversion, it's essential to unmount the ISO file to release system resources. To unmount the ISO, use the following command:

sudo umount /mnt/iso

This command unmounts the ISO file from the specified mount point (/mnt/iso).

So above are all the steps you need to take to convert ISO files to MP4 format using FFmpeg.

MakeMKV, known primarily for converting DVDs and Blu-rays, can also handle ISO files. However, it operates by remuxing the MPEG-2 video into an MKV container. Subsequently, an additional step is required to convert the MKV file to MP4 format.

Here's how to accomplish this:
