How to Convert ISO to MP4

By Alexis Lawrence

ISO files are image files that contain the numerous VOB video files used on a standard DVD. Because an ISO is not a video file in itself, you cannot directly convert it to MP4. First extract the individual video files from the ISO image file, then convert the video files into MP4s.

Convert the ISO to VOBs

Step 1

Download DVD Shrink from the DVD Shrink website (see Resources). This free software extracts ISO files from DVDs, then grabs the VOB files from the ISOs.

Step 2

Open the ISO file in DVD Shrink. Click the "Open Disc" button, browse for the ISO on your computer and click "Open" when you find it.

Step 3

Click the "Re-author" button at the top of the DVD Shrink screen. All of the folders and VOB files stored on the ISO file will appear in the right pane, broken up into categories, such as "Main Movie" and "Extras."

Step 4

Drag the files you want to convert into MP4 from the right pane into the left pane of the DVD Shrink window. If you want to convert the entire ISO, pull all of the files into the left pane.

Step 5

Click "Edit" and select "Preferences" from the menu. Click on the "Output Files" tab, check the box next to "Split VOB files into 1GB size chunks," then click "OK."

Step 6

Click on the "Backup!" button. Choose the "Hard Disk Folder" option under "Select backup target," click the "Browse" button to choose the folder where you would like the VOB files to save, check the box next to "Create VIDEO_TS and AUDIO_TS subfolders" and click "OK." The program will convert the ISO file into separate VOB files and save them to the location you chose.

Convert the VOB to MP4

Step 1

Go to the website Media-Convert.com, which provides an online conversion system that can handle numerous types of conversions, including VOB to MP4.

Step 2

Click on the "Browse" button to upload a file to the converter. The "Input format" box will fill in automatically when the file uploads.

Step 3

Use the pull-down menu next to "Output format" and choose "MPEG advanced audio coding (.mp4)." Click the "OK" button to start converting. Your screen will monitor the progress of the conversion.

Step 4

Download the MP4 file from the link provided on Media-Convert. Right-click on the link and choose the "Save As" option to select a folder where you would like to save the MP4 file.
