Problem in converting AS3 based swf file to mp4 file

Not sure if this would work for you but there is a Export Movie as an MOV file from Flash. Under the File -> Export Movie options, you can pick a video format. It might not work because of your ActionScript. Not all AS code changes get picked up by this method of creating a movie file from Flash. The other option would be to have a desktop screen recorder application to record your actions on the desktop as video and you play the SWF file while your desktop is being recorded. Then you would just need to crop the video to the SWF window. Both options should probably be done in a raw format, like Animation, for the output file so you can compress it to your hearts content from a raw source. It will however give you much larger file sizes, so make sure you have a decent HDD if you try either of these options.

Hi,

Thanks Kglad for your suggestion. Yes I already do that where I use a SWF to video converter - which essentially uses published SWF to create a MP4 video. However,  it is a manual process (bring up the tool, select the swf file and click convert). I have many SWF files (with actionscript) and hence I want to automate the process so that this conversion runs in the background. So I am exploring various tools...if I get the exact images on each frame (as a result of actionscript and not just base animation) then I can join those together to create video with ffmpeg. Or is there any already existing solution which helps me end-to-end in automating my SWF to MP4 video conversion? Please let me know.

publish a swf and use capture video to create your mp4.
