Slight correction: I was importing an .avi file. My understanding is both FLV and F4V are Flash - which is a bit of what concerns me. It appears that Captivate wants to convert to Flash and then possibly back out of Flash if I publish to HTML. It's this kind of artifact that has me worried about Captivate's future and if I should be using some other kind of software instead. I appreciate your info, I know predicting Captivate's future is a tough question to answer.
Indeed, for an avi file it will need Adobe Media Encoder to be converted to mp4. It will not be converted to FLV/F4V at all. Look in the project library please!
You may have missed the September 2021 eLearning conference, where a sneak peek of a completely redesigned Captivate version 12 was shown. That version will for sure not have any output to SWF, only to HTML5. But as I mentioned HTML5 output is possible with Captivate since many versions.
