this does not work, fail after way too many captchas required to continue, and vague directions, not clear what next step.
finally got all the way to last step to finish, and repeated message
Last export generation failed! Last export generation failed! Last export generation failed! Last export generation failed! Last export generation failed! Last export generation failed! complete waste of time here - worse not able to use any audio, video or gif source from anywhere but swfchan.org
The problem was that one of the images in the "Quality: High" selection couldn't be put into the flash. It happens sometimes due to some small error in the format encoding, if you pick a different quality setting it will work (was a message about that below "last export generation failed").
I know the user experience of the swfloopmaker isn't very good, if I had designed it today I would have made it much clearer with less captchas and less text.
