Flash to HTML5?

I am redesigning an old website which is containing some Flash stuff. I would like to do it in HTML5 so this can be seen on iPad, etc. I don’t have the .fla file just the swf. I tried a couple of tools which are supposed to transform flash files to html5 but none seems to do the job.
Am I doing the wrong way ? The stuff I need to transform is located at the bottom of this page where it says “Galeria Multimedia de Aberturas”

I would probably convert those animations into video, rather than an HTML5 canvas.

I haven’t tried this particular tool myself, but it looks like it might be an option: http://www.freeswfconverter.com/

Other options: https://www.google.com/search?q=swf+to+video

Personally, I would steer well clear of tools that automate something like that. The code they spit out is likely to be awful. It’s really simple to recreate that gallery in HTML. I would use a jQuery script like slimbox2 for the gallery, and because the animations are so simple, I’d recommend trying animated gifs. They are perfect for those animations, and cross-browser friednly.

I’ve just been playing around with a free tool that converts videos into animated gifs, http://www.gifrocket.com/, and it’s insanely good. Worth a try (if you’re on a Mac), or I expert there will be PC equivalents.

Thank you guys, I am trying a couple of software running on windows to convert those swf files to gif or video. After a few tries I reckon I’ll go for gif as video output colour isn’t good enough
