[Avid-L2] DNx145 or XDCAM HD 50Mbit - which is easier to cut with ?

 

OK - we've been doing some remote editing using standard MacBookPro 2.53 Intel Core Duo w/4BG ram. We have anywhere from 3 to 7 44min eps to pull bites & b-roll from to cover intvw footage. One of our engineers suggested we ingest using the XDCAM HD 50Mbit (1080i/60) codec in order to save drive space. What I'm finding is that the system bogs down & really struggles - spinning beach ball, etc - when trying to access that footage using AMA (I know Avid does not recommend using AMA to edit with) so I ended up re-importing (instead of transcoding) the episodes at DNx145 and while that took considerable time it turned out that the DNx145 is much easier to edit with. Far less spinning beach balls.
Is the XDCAM codec more processor intensive because of the compression ?

Also - I know more RAM is always good, but does anyone think it would make a really noticeable difference ?

Thnx in advance

Dave B
