I would suggest a professional codec like DNxHD which can be decoded and encoded on all platforms and is very resilient.
When you say a 2″ master, are you referring to Standard Definition video?
Is this going to be converted to HD? By them or you?
What system and software are using to edit this?
These are more details will be helpful in avoiding issues.
