how to convert swf to flv for youtube uploading?
i've tried to upload a the swf file to youtube but there is an error : Failed (unable to convert video file)
i've tried SUPER, but when i add .swf file it pop put an error message too: your .swf input souce file doesn't use the flv or vp6 video codec. it rather uses an un-supported video codec.
what can i do? how can i convert swf to flv for youtube sharing?

 

thanks for your focus on my problem! i've tried that, it does support .flv format but not .swf, although both of them are flash vdieo, i found another iwisoft swf to flv converter myself and the problem fixed.
thanks again!

 

thanks for your recommendation, but it can't import .swf, i've found a iWisoft swf to video converter and problem fixed, thanks again!

 

Thanks for that

I'm sure it will help others with the same problem

and be noted for future, should anyone else have the same problem

 

well, i hope that can help others indeed, it's not that easy to find a proper one because .swf file is not that compatible with many programs no matter player or converter no matter free or pay, if anyone need it's here convert swf to flv

 

I am sorry Jayjoy but I am bothered by this link and and the fact that you have posted it more than once and return to post it again. (I removed the previous links.) Frankly I do not trust software that is advertised without a publisher or any reviews. I have decided to leave it for now pending research but I do think a warning to be careful is appropriate.
