Jose Antunes has an article at ProVideoCoalition on the recently released upgrade to LumaFusion for iPad, version 3.0. The update includes stabilization software from CoreMelt, and the ability to use external drives, especially for the new iPad Pro with USB 4.0. It also has a new graphic equalizer.
I have actually used LumaFusion as it is the most standard type editing program on iPad, if you can use Premiere or AVID you can easily use LumaFusion. It is well worth it’s $29.95 price.
