I'm looking the replicate the effect of cutting steel with a torch in AE.

If found this FREE video source (http://www.detonationfilms.com/free_stuff.htm video==> Titanium Squib bursts from side wall ) and it's pretty close to the effect I want... Except when I re-edited it to replicate continuous cutting (I need approx 10+ secs worth) it doesn't look right because the source video is too short.

Is there another resource for similar video clips available - or- another way to replicate the effect?
