AVI (Audio Video Interleave) format is the most common video format used by Microsoft Video for Windows multimedia framework. Movies in the .avi format are a series of fast moving of captured bitmaps that show the movement of screen elements. The size of the .avi file can sometimes become fairly large based on the size of the window being captured, the speed of the frames and the length of the video capture. If you want to reduce .avi file size you can lower the frame rate, remove irrelevant elements in your screen capture window and try to keep the length of the screen capture shorter.

Want to reduce .avi file size?

Flash Video Recorder distribution package includes a module known as the SWF Converter that is able to convert an AVI file to SWF. This is actually a separate program that can function independently of the Flash Video Recorder.

With Flash Video Recorder you can solve this problem of large .avi files very easily by using the SWF Converter that is included with Flash Video Recorder. The SWF Converter will convert your AVI files into FLASH files. SWF converts AVIs to Flash files in a lossless manner meaning there is no degradation of image quality or decrease in frame rates.

The process of recording to SWF actually involves multiple steps. Flash Video Recorder records your screen activity to an intermediate AVI file first, before converting it to a Flash (SWF) file. The Delete the intermediate AVI file upon completion setting thus instructs Flash Video Recorder to delete the intermediate AVI file when the conversion is completed. You may want to preserve the AVI file just in case you’ll like to edit it in an AVI editor, but that will take up plenty of space on your hard disk, as the format of the AVI is saved with minimal compression settings.
