SWF & FLV Toolbox offers conversion of Macromedia SWF files into AVI video format using any codec installed in your system. You may select necessary codec from the "Select codec" drop-down menu option. Please, note that to be able to view encoded video files your end-users need the same codec installed in their systems, so if you want to spread your movie files to wide range of people make sure you use the popular codec.
There are two types of SWF to video conversion technologies: frame-by-frame and interactive video conversion which allow you to convert non-interactive and interactive SWF movies respectively.
1. Frame-by-frame video

Frame-by-frame option is the best choice for the linear movies capturing that don't require user's activity (mouse/keyboard events).
SWF & FLV Toolbox lets you select the codec, which will be used to encode the resulting video file. Simply select the required one in
select codec combobox where all codecs, installed in your system, are listed. To avoid problems while playing back the resulting movie on different PC, please, use standard video codecs.
Video quality option could considerably save resulting movie size (and upload/download time as well) on the one hand and essentially decrease movie quality. Try to experiment with different values to get satisfactory size/quality result.
Keyframes interval option defines how frequent control points (keyframes) have to be taken during the capturing process. This option indirectly affects the resulting movie quality: the more keyframes, the smoother the movie, however the downside is the size of the resulting move.
"
Add original streaming sound" checkbox allows you to enable/disable streaming sounds for the resulting movie. Additionally, you may specify bitrate and sample rate values as well as choose from stereo and mono sound reproduction modes.
Bitrate is the number of bits per given time interval (usually per second), used as a measure of information flow. The higher the bitrate is, the greater the audio resolution will be generated in the output file. 128kbps is a current MP3, audio CD and video CD files bitrate standard.
Sampling rate is the number of samples (per second) that are taken to convert analog signal into digital one. It is measured in hertz (Hz). Higher sampling rate provides better quality reproduction, however it requires more space on hard disk. Use sampling rate slider to specify output Flash sound quality. 44100 Hz is an adopted standard for audio CD, video CD and MP3 files.
2. SWF interact video 
"SWF interaction video" option allows you to capture interactive SWF movies (games/presentations/etc.) and into AVI movies using any codecs installed in your system. Additionally, SWF & FLV Toolbox can capture the mouse pointer movements (
Capture cursor movement checkbox), which could be invaluable for step-by-step how-to's.
SWF & FLV Toolbox allows you to preview Flash movie and capture the whole SWF file as well as its parts by dragging the slider forward and backward on the time line. Additionally, it provides the unique ability to zoom in and capture the particular part of SWF file image. Simply move the slider in the lower right corner of SWF Interaction Video Capturer, move your mouse pointer into zooming window and while holding down left mouse button, move it to the part you want to be captured. This option could be indispensable if you would like to emphasize/highlight the specific part of the image, especially if the original SWF image size is big.
Video and audio capturing options are similar to ones of "Frame-by-frame" and are described above. In addition, you may see "Capture cursor movement" checkbox and "Sound device" button which are available for interactive video processing only. "Capture cursor movements" lets you capture all mouse pointer activity in the resulting movie file. "Sound device" button offers the advanced list of audio sources for the record ("Line in", "Microphone" and so on).
Below are the steps which could be followed to convert your SWF movie into video file:
