I'm just begining on Avid. What computer would you suggest me to buy(budget~$3000)?
and what's the differece between Avid Express Pro HD, Avid mojo, Avid media or Avid simphony?
I would suggest you do a tour of www.avid.com to get a sense of the product lineup. There are software only solutions, software and hardware, etc. all at different price points.
I would most likely think you are interested in Avid Xpress Pro HD (no renamed back to Avid XPress Pro with version 5.2). Are you looking for Mac or Windows?
Basically. There are extra features or fewer features depending on which way you go in Avid's product line, but if you learn the interface that knowledge will transfer across platform and software.
Linear means a straight line, meaning you take a placeholder and start putting video on it only being able to overwrite. Say if you have 2 vcr's and want to edit peices from one to the other, fast fowarding until you get to what you want, the recording that with the other. Thats Linear.
So Non-Linear is the opposite. Its just that you can overwrite, split, join, and push around videos at will without having to mess up your video footage for the final product. Non-Linear is just the timeline like the VCR Tape, but you can drag and drop things anywhere moving around footage as you please in real time. Thats the way most all editing is done these days, with computers atleast.
My personal opinion: If it's not an Avid approved system, then you're taking a gamble (esspecially using AMD). For a list of Avid Approved computers, go to www.avid.com.
