Hi guys:

I whant to start to have a backup for all my work with the best quality posible.
I edit in Avid Xpress Pro 5.2 . Can anyone tell me what´s the best way to export so that i can have the cosest quality to the one on the sourse DV tape?

I would suggest uncompressed .avi but someone may have a better suggestion.

Lossless codecs like Huffyuv or animation will give you smaller file sizes.

You could also print to miniDV tape. It might be your best option, because hard drives can crash. And DVDs can get unrecoverable errors after just a year (lots of factors here).

That's what I usually do as well, print the final project back to tape and store it.
