Playback and Review Standards

Metadata Standards

First Frame, Last Frame	Encoding to movie files typically looses the start frame, making it a pain to identify which frame you are looking at. We could look at doing this with timecode, but sometimes you want both timecode and a frame number.
Source filename	Something to track where the encoded media came from.

Use existing metadata values where possible, and fall back on XMP where not.
