Step 2. Press Win + R and input cmd to enter the DOS window.

Before the conversion, 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.

Next, 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. 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).
