SCAIL 2 Long-Form Editing: Four Reference Workflows

Four SCAIL 2 workflows focused on long-form reference editing — single and dual subjects, people and creatures.

The four workflows

# Workflow Subjects
1 Single-reference edit, long video 1 person
2 Single-creature long-video drive 1 creature
3 Dual-reference edit, long video 2 people
4 Dual-creature long-video drive 2 creatures

The long-video problem

Reference editing works well on short clips and gets harder as length grows: the reference drifts,
the identity softens, and body proportions wander. These four graphs handle it by re-anchoring on
the reference at segment boundaries rather than conditioning once at the start.

Dual-subject is the hard case

Two people means two identities that must not merge. The dual-reference graphs keep separate
conditioning streams and only merge them at the sampler, which is why they survive longer than a
single combined prompt.
