SWF TabThe SWF tab is where you set the SWF options for your encoded media file, such as SWF framerate and additional custom variables.
Movie OptionsIf you select "Protect movie from import", your SWF media file will be protected from import into Flash. People who attempt to import a protected SWF into Flash will receive an error and be unable to do so. Do not do this if you intend to import your video into a larger project within Flash.
Directly beneath that option, you may choose to have your SWF loop. When checked, this will cause your SWF media file to loop automatically and infinitely. Otherwise, your SWF will play once and stop.
Next is the "Unload movie at end" box. If you check this box, your SWF movie will automatically unload once it has finished playing. This will return all the RAM the SWF Player has used back to the system. It will also mean that the unloaded media file must be re-loaded prior to being viewed again. All the video presets have this box selected.
Keep in mind that "Unload at End" and "Loop Movie" are mutually exclusive, because once unload, there is no movie to loop.
The "Framerate (fps)" field is where you set the SWF framerate, which is the number of frames per second encoded into your SWF. This is not your video framerate, which is the number of video images per second encoded into your SWF. If you are loading or importing your video into a larger Flash movie, the SWF framerate of your video must be the same as the framerate of your larger Flash movie. Otherwise, if your media has MP3 audio, your larger site will play back at the speed of the media file; if your media is video-only, your media file will play back at the speed of the website.
Your SWF framerate must be at least equal to, or a multiple of, your video framerate (which you specify under the Video tab).
Custom VariablesIf you wish your media file to hold additional variables (to denote additional clip information, or to set variables to interact with larger Flash movies), you may do so by entering a variable name and its value, and selecting "add". This will add the new variable to the list window.
For example, you may wish to add the variable with the name "encode_date", and the value "2001_03_15". Variables in Flash may contain letters, numbers and underscores (_). Please avoid punctuation and other special characters.
Once a variable is in the list, you may update or delete it by selecting the variable in the list window and clicking either update or delete.
