Hi Job,
Couple of consideration:
-get a deck with dual laser, like the PDW-HD1600 or the PDW-U2. It will speed up the copying process significantly
-if you were to go DNxHD and finish in that format, go with the highest quality, ie 185, especially because of transcoding. If there is color correction involved, I'd go with 185x for its increased bitdepth
-i'm with Greg on staying native, moreso by knowing there is a chance of an XDCAM delivery. It saves time and space, also it preserves 100% original quality. Recompression is never a good thing, and in your case it might be needed twice(you'll need to find out the exact delivery specs).
Yes, it might affect performance, and number of RT effects available at once, but the benefits are chunky.
cheers,

Subject: [Avid-L2] XDCAM HD workflow check

List,
Looking for feedback on an XDCAM HD workflow for a 50-minute show, as I've mostly dealt with 35mm, Red and Alexa over the last few years.
My plan:
- receive XDCAM HD disks from production
- copy contents of XDCAM HD disks to a hard disk (preserving the folder structure of the disk), send back the originals for archiving
- AMA-link to the copies on the hard disk
- transcode the AMA-linked clips to DNxHD 120 or 185 for editing (this is 25p or 50i)
- edit away
- export to color correction and sound post
- marry graded picture and mixed sound, add captions / graphics after color grading
- playout to tape or export to file (yet to hear delivery requirements, I'm betting Op1A MXF export is required)
The reason for the transcode is that DNx will play much nicer with the system (Symph v6 /w Nitris DX on XW8600) than the native MPEG files, right?
Also, transcoded media will let me do Same-As-Source exports in-between and make for faster rendering, right?
120 should be high enough when the source is MPEG50 or lower, right?
Anyone have a clue what transcode times I'd be looking at?
Many thanks,
J.
