Function snapshotProject

Turns a document into something a test can compare or pin as an inline snapshot. Two projects that look the same to a user give the same result, whatever ids they carry and whatever order their rows were created in.

Sort: media assets by filename, then id tracks back to front by the stacking rule (compareStacking) clips by track, then start_time, then id effects by clip, then order, then id keyframes by effect, then param_name, then time, then id transitions by outgoing clip, then incoming clip, then id "By track" and the like mean the position of that row in its own sorted list.

Label: every id becomes asset#n, track#n, clip#n, effect#n, keyframe#n or transition#n, counting from 1 in sorted order. Every foreign key becomes the label of the row it points at.

Drop: file_path, file_size and proxy_path on media assets (the file is named by filename). The document already has no created_at / updated_at.

Numbers are rounded to 6 decimals so float noise never breaks a snapshot.
