The conversion has two stages: first make the DVD content inside the IMG accessible by mounting or extracting it; then load that DVD source into the converter and choose the output format you actually need. MP4 is used as the main example because it works on most devices, but the same steps also apply to AVI, MKV, MOV, MPG, WMV, MP3, and other supported profiles.
Mount the IMG File
π Method 1 - Mount the IMG as a virtual DVD drive.
If Windows shows a Mount command for your IMG file, right-click the file and select it. The image will appear as a virtual DVD drive in File Explorer. If the Mount option is unavailable for your IMG type, use a trusted disc-image mounter instead.
Step 1. Open the folder that contains your IMG file.
Step 2. Right-click the IMG file and choose Mount when the option is available. Then open This PC and note the new virtual DVD drive letter.
On older Windows versions, or whenever Windows cannot mount the IMG directly, you can use a third-party image mounting tool such as DAEMON Tools Lite.
Extract the IMG File
π Method 2 - Extract the DVD files instead.
If the IMG is unencrypted and your archive utility like 7-Zip can open it, extract its contents to a new folder. A DVD-Video IMG normally contains a VIDEO_TS folder.
Keep that VIDEO_TS folder inside a parent folder; later, load the parent folder through DVD Folder in WonderFox DVD Ripper Pro.
