[Openexr-user] Image Sequence Container

[Brendan Bolles]

Has anyone here ever experimented with ways to treat an image sequence as a 
single entity?  Obviously sequences have plenty of advantages, but there's also 
something to be said for monolithic movie formats where there's one set of 
metadata for the entire clip, and maybe even an audio track to go along with 
it.  Movies also simplify things from the user's perspective.

Has anyone tried to extend EXR into a kind of multi-frame movie format?  PNG 
has the seldom-used MNG companion format that does this.  Maybe an existing 
wrapper like MXF could be used?  I just want it to be open source and 
float-friendly.

On Mac OS X, certain file extensions like .xcodeproj automatically turn a 
folder into a "package" so it looks like a single file.  I could imagine using 
this along with maybe an XML file to come up with a standard way to wrap image 
sequences with some more intelligence.  And since you'd still have a sequence 
at the core, you could still network render and do the other nice things we're 
used to.
