I'm working at the National Library of Norway, where we are about to start scanning all our films in 2k/4k, and we are deciding on which delivery format to use for external clients. (We will of course archive everything in uncompressed full rez DPX glory, but need a lighter format for FTP transfer to external video productions.)
When you receive footage for inclusion in your SD/HD project, (for example archive material in a tv documentary; not intended for cinema exhibition):
1.) Which codec do you prefer: mpeg2, h264, DNxHD, XDCAM or Prores?
2.) At which minimum bit rate?
3.) Most footage is in 16:9. When receiving material in HD, do you prefer it in Standard 1080p (1920x1080) with black borders; or in 1440x1080?
Bonus question: is anyone using MXF files yet?
Thanks for your help!
