1. How to make FLV files?

Step 1: Open Flash Professional 8 and establish a new flash docment.

Step 2: Input AVI video files(this is the common video format that is frequently used by your DC or DV) that you want to convert to FLV and follow the instructions.

Step 3: Keep the default setting for “Edit” and “Encode”, click “Import video” and
then “Next step” and “Finish” at last to complete the inputting process.

Note: If you don’t have Directshow 9 and QuickTime 6.5 or higher installed in your system, a pop-up window will remind you to do so in order to import AVI successfully. Or, if you want a much easier way to do it, try Moyea Video4Web Converter, it’s free and just a few clicks can complete the conversion from AVI to FLV.

Step 4: Press “Ctrl+L” to open the data base, double click the AVI file just input, open “Embed video property” interface, click “Output” to create a FLV file.

Above 4 steps lead you to convert AVI to FLV successfully and after conversion, you will surprisingly find the final size of FLV is just 541KB, much smaller than the original 23MB AVI. Now you can use it freely on Internet.

2. How to use FLV files?

Some meanings of parameters in Component Inspector:

File Type: choose FLV as the defined file type, you can also choose to play MP3 file.
