Portfolio: using suboptimal video to show interactivity?

I’ve tried to get video screen captures of my best work for my portfolio to show the interactivity of the Web apps, but the quality is not all that great. The videos are Flash .SWFs, and I’m not sure that I have access to all the original .FLVs. Do you think I should continue to use the .SWFs, go to the effort of finding all the original .FLVs and have them re-encoded, or…?

you may be used.swf its good and easily convertible and websites also allow these format
