If SWF To Video SDK generates blank video then please try the following: - run Internet Explorer browser and check if Adobe Flash Player plugin is installed. Try to visit Adobe.com using Internet Explorer to check if flash player animations are playing in Internet Explorer. If not then update flash player plugin following the instructions from Adobe.com. - if you are converting SWF to WMV video then make sure you have the latest version if Windows Media Player installed (especially if you are running on Windows Server version where you need to install Windows Media Player from Desktop Experience section). - if you are running the precompiled source sample code then please try to open it in Visual Studio and recompile and then run again in x86 CPU mode.
