What program should be used to convert a dynamically generated Flash movie (SWF) to a video file on the server?

Question

Video

The task is the following (do not judge strictly for possible incorrect formulations):

1) The input is a dynamically generated SWF file consisting of a video stream and dynamically loaded data (images). That is, before starting the conversion to swf, parameters (url of images) are transmitted via flashVars, which must be loaded and added to swf 

2) It is necessary to convert the swf file to a video format (mpg (mpeg-1), mp4 (for playing on iphone) This video file, when playing, must be completely identical to the SWF file (all elements displayed in the SWF file must be displayed), including  sound.To

implement the task described above, we use the (demo version) program:
www.swfkits.com/swf- to-video-sdk/, but we are not sure that this is exactly what we need. This is due to the fact that we set a high peak conversion load (up to 500 conversions per minute).

There is practically no experience in this area.

Answer 1

Video should be prepared in video programs, even if it is dynamic. The fact that you get video as a result of flash playback is, of course, a simple option. But with such a statement of the problem, you have no other alternatives. If the resulting video is not unique, you can try caching the result

What's wrong with ffmpeg/mencoder?

I used gnash in exactly the same situation.
