The reason there is no standard document is that each facility has their own methodology. For example, audio being exported to OMF. I leave dissolves & transitions, plus levels and 3 second handles. This may not suit other sound post facilities but that is what we use to go to Fairlight. It is nice if all dialog, narration, music etc has been kept on discreet channels, but it is so much faster to move things in Fairlight, that we often advise editors not to waste too much time doing track management before handover when deadlines are tight.
Prepping for Color has some basic rules about removing stills and speed changes, but I often leave speed changes in which is fine in Color 1.5 but has the consequence that you can’t keyframe grades on those shots so I make a judgment call during prep. Again no hard and fast rules. Most important is to know what causes problems.
By far my biggest issue when getting a locked off cut from an editor to grade, online and sound post is poor media management and text that has been wireframed into rough position leaving hundreds of motion values to be rounded down from fractions or luminance values of text to be trimmed and matched. The media management issue also shows up poor reel naming and clip naming techniques. So by far my biggest issue is not with prepping to handover, but the initial pre post methodology by editors and assistants, plus the annoying directors that just drop in some temp music or graphic with all the wrong settings and resident on the system drive so offline when delivered to me.
So please write the book on prepping to start post and you will find that the most important issues in prepping to hand over to online & sound post are already 90% right. Search for some excellent tutorials here including recent ones on ingesting and managing file based camera source.
