Swivel is a free solution for converting your Adobe Flash movies into high-definition video. Swivel takes an SWF file and exports a video at any desired resolution, complete with audio and no dropped frames. Best of all, Swivel is completely free, made out of a desire to help the animation community.
For simple movies, Swivel makes converting your Flash movie quick and easy. Just follow these steps: click the "Add" button next to the the "Input SWFs" list; select your SWF file; press convert. That's it. The default settings will export a 1080p quality MP4 in the same folder as your SWF file. When the conversion is complete, you can click the file name on the completion screen to immediately open the video in your default video player.
For movies with a preloader or other menus, you can skip these segments by changing the Start Frame and End Frame settings. Swivel shows a small preview of the selected frame so that you can ensure that you are skipping any unwanted content. For complex movies, or if all else fails, you can use Manual mode to interact with the SWF and manually start and stop the recording when ready.
