Step 1: Click "Open File" button on the "Input Video" field after launching Flash Video MX.

Step 2: Find the video file you want to convert from your computer hard disc or peripherals. Click "Open" on the bottom left after selecting the file or double-click this file to input it to Flash Video MX.

If the input video file is supported by any codecs installed on the computer, the file will be loaded into the program. If there is no codecs on the computer that supports the input file, you will see a pop-up window that asks you to download the proper codecs so the input file can be loaded with no prolem.
