The reason may be you didn't uninstall previous version before you install V2.4. Version 2.4 is not compatible with the previous, so if you install V2.4 before your uninstallation, it will bring you trouble. To solve this problem, you just need to uninstall V2.4, and reinstall it. If this doesn't work, please tell us.

To play output files, correct decoder should be installed on the computer. For example, if you want to play AVI files encoded by DivX, you should install DivX decoder on your computer.

The final output quality depends on the video codec and the video bit rate. With the same bit rate, MPEG4 is the best. With the same codec, the higher bit rate, the better quality and the bigger final file size, vice versa. (To set the bit rate, please click the button "Configure" in Conversion Parameter dialog to call the codec program itself, which is not set in SWF to Video Converter.)

You can adjust the video size in Step 3 "Conversion Parameters". In the settings of "Size of Video", choose "Customize". Recommend you to keep the lock option pressed, which is used to constrain the proportions of the movie's width and height. And then input the desired value of width or height into the box.

At first, make sure you have chosen "Interactive" as the convert mode. Then in the step 4, when you see the Capture window, click button "Play" to play the movie. And click "Start Capture" when you see the frame which you want to be the first frame of your file. Click "Finish" when you see the frame that you want to set as the last frame. If you want to capture from the beginning, you can just click "Play and Capture". And click "Finish" when you see the frame as the last frame

To record sound from current swf file, please make sure "Stereo Mix" is set enabled and working. You can double-click "Volume" icon ("Sound" icon in Windows Vista) on Windows Taskbar to open the Volume/Recording Control panel (Sound panel in Windows Vista). You can also just click "Open Sound Panel" on the prompt to open the panel. And then enable "Stereo Mix" and choose "Set default" from command menu.

Because the movie in captured by single frame individually in this mode, it is impossible to get the sound at the same time of capture. But you can import an exist sound to your movie in conversion parameter settings.

In interactive mode, users can interact with the SWF file such as clicking the buttons in the movie, etc. especial for some Flash games. So its playing is up to user's action.

Sothink SWF to Video Converter can convert your SWF file to AVI, 3GP, MPG, MPEG, MP4, GIF, animated GIF, PNG, BMP and JPEG.

All the SWF files applied in Flash standard can be converted.
