The free and open-source VLC media player can play most common audio-visual file formats, including AVIs, MPEGs and WMVs, as well as DVDs and CDs. The program also lets you configure and edit files with cropping and de-interlacing features. If your media plays too quickly or slowly, you can adjust its frame rate.
Click the "Media" menu in VLC. Choose "Convert/Save" to display the "Open Media" dialog box.
Click "Add" to display a file dialog box. Navigate to the file with the frame rate that you want to change. Double-click to load it into the "File Selection" list.
Click the "Convert/Save" drop-down menu and choose "Convert."
Click the "Edit" button with the wrench/screwdriver icon.
Click the "Video Codec" tab. Put a check mark by "Keep Original Video Track," if you want to keep the original sound. Choose "1" from the "Scale" drop-down menu to keep the original frame size.
Enter a new frame rate in the "Frame Rate" box. A typical rate is 30 frames per second. Enter a bitrate such as 100 kilobytes per second. Click "Save" to return to the "Convert" dialog.
Click "Browse" to specify a location and a file name for the converted file. Choose the file type for the converted file in the "Profile" drop-down menu. Click "Start" to convert the file.
