Re: Workflow Decision Time - XDCAM EX

My understanding is that XDCAM HD is a variation on MXF, ie MPEG2 compression, but all I frames, so each frame is independent, just like any motion jpeg codec.

HOWEVER EX is more like HDV, in that its MPEG4 using I B amd P frames, so the CPU has to work a lot more to "fill in the blanks" when ediitng, making up B and P frames and making them editiable.

hope this helps
