SwfDrop

SwfDrop is a lightweight and straightforward piece of software that can encode files from Flash videos (SWF) to Audio Video Interleave items. It can be seamlessly handled, even by first-users.
This tool does not require installation, so SwfDrop is portable. It means that you can store the program on a USB flash drive, save it to any computer and directly run its executable. Plus, no leftover items can be found in the Windows registry or on the hard drive after program removal.
The app is wrapped in a small interface with a simplistic layout. Importing video clips can be done with the help of the 'drag and drop' method. Unfortunately, you cannot process multiple items at the same time.
Once you have selected a video for processing, you can choose the video compressor and adjust the compression quality. The audio track of the clip can be heard on the background during this time.
SwfDrop takes a very long time to complete a task (usually longer than the length of the clip) while using a pretty high amount of CPU and system memory (if we take its limited features into consideration). It has a fair response time.
However, you cannot specify the output directory (videos are automatically converted to the same location as the program). Plus, you cannot preview the video in a built-in media player or configure audio settings (e.g. channel mode, volume level). SwfDrop didn't manage to convert the audio stream of a video during our tests. No recent updates have been made.
