Join (Merge, Combine) Multiple SWF Files Into One

As the name explains, Join (Merge, Combine) Multiple SWF Files Into One is a software application which allows you to merge two or more Flash video files with the SWF format. It can be easily figured out, even by inexperienced users.
The app's interface is based on a standard window with an uncomplicated layout. Importing items into the file list can be done with the help of either the file browser, folder view or 'drag and drop' method.
You can add as many SWFs as you want, and initialize the merging procedure by clicking a button. In addition, you can remove an item from the list or clear the entire file queue. Unfortunately, Join (Merge, Combine) Multiple SWF Files Into One does not give you the possibility of specifying the output directory.
Furthermore, you cannot preview clips in a built-in media player, configure audio and video settings (e.g. frame rate, channel mode), customize the numbers of CPU cores in use, or make Join (Merge, Combine) Multiple SWF Files Into One minimize to the system tray area.
We have experienced several issues throughout our testing. The app takes a while to finish a task, during which it looks as if it hangs. Once the job is done, you should be able to preview the resulted clip in a built-in media player but we were unsuccessful in our attempt to do this; the demo version does not allow you to save the output videos. No recent updates have been made to the app.
All in all, Join (Merge, Combine) Multiple SWF Files Into One needs some further improvements to be taken into consideration as a serious video conversion tool.
