19 Omni jobs or 7 Wan jobs: Timeline render strategy for 181 s

The model you pick for the clips decides the clip count, and the clip count decides how the Timeline renders. Timeline 1.0 has a render.strategy field: auto (the default, chunks past 12 segments), chunked, or single. Sume refuses single above 12 slots with render_strategy_unsafe.

Clips and strategy

Counts are from the even split of 181 seconds in the planner post.

What to send

Leave strategy on auto. You only need to know that a long list of short clips is rendered in chunks, and that sending single with 13 or more slots returns render_strategy_unsafe. See the render strategy post.

Count is not cost

Fewer, longer clips is not automatically better. The price of 181 seconds on Wan and Omni is the same at 720p ($22.63), so choose by how many shots you want to control.
