iTunes only supports the MP4 (M4V) and MOV formats. It does not support many popular formats, including AVI, MKV, and WMV. If your video files are not the proper format, you won't be able to add them to your iTunes library. Check your video's format before proceeding. If it is an incompatible format, follow this section to convert it to a compatible one. If the video is already in MP4, M4V, or MOV format, skip down to the next section.  Windows - Right-click on the video file and select "Properties." Check the "Type of file" line in the General tab for the file format. Mac - Control-click the file and select "Get Info." Check the "Kind" line in the General section of the Show Info window. This is a freeware video conversion program from Macroplant that can quickly convert your video files to an iTunes-compatible format. It is available for both Windows and Mac. As long as you download Adapter from macroplant.com/adapter/, you shouldn't have to worry about adware. During installation, make sure to keep the "Download and install FFmpeg" box checked. This is required for the conversion process. FFmpeg is open-source and adware-free. You can drag all of the files that you want to convert, or just add single files at a time. You can also click the "Browse" button in the Adapter window and navigate to the files you want to convert. This will allow you to select what format you want to convert to. This will set Adapter to convert your files to the MP4 format, which is compatible with iTunes. If you're adding these videos to iTunes so that you can sync them with your iOS device, select the preset for your iPhone, iPad, or iPod in the "Apple" section of the Output menu. This menu will allow you to adjust some of your settings before converting.  You can change the destination for your converted files at the top of the menu. The "Quality" menu in the Resolution section will allow you to set the quality of the image after conversion. "Medium" is the default setting, which will result in a smaller file size with a minor drop in quality. If you want to keep the original quality of the video, select "Very High (Lossless)." This may take a while to complete, especially for longer videos and older computers. By default, the converted videos will be in the same location as their originals. Find them so that you can add them easily to iTunes.
