Also keep in mind that Axio LE supports HDV native editing, plus you can mix HDV, DVCPRO HD, Uncompressed and MPEG-2 compressed on the same timeline without rendering. Because DeckLink is a basic I/O solution, if you mix formats you are going to have to render. Also, if you capture using native HDV with Premiere Pro, DeckLink will ignore this as it only works with uncompressed HD and not HDV. Like i said, Axio LE will capture, edit and output HDV without any problems so you can see your HDV edit on an output monitor while editiing.
Even if you don’t use any of the effects that Axio LE gives you, this alone may sway it for you.
