How do you choose between sequential and parallel pipeline work?
Use dependencies to identify which generation steps can run together and which must wait.
How do you choose between sequential and parallel pipeline work?
Parallel execution can reduce waiting, but only when tasks have independent inputs. Starting everything at once can waste work or produce mismatched artifacts.
Follow actual prerequisites
Narration must use the approved script. Caption alignment needs the narration audio it will describe. Some visual-asset preparation may run alongside speech generation once both have stable inputs. Document those dependencies before choosing an execution order.
Balance concurrency against constraints
More simultaneous tasks can increase memory use, provider traffic, and cost. Start with bounded concurrency and measure the full job, including time spent waiting for services. Define how results are joined and what happens if one branch fails. Keep artifact versions attached to each result so a late branch cannot join the wrong revision. Try a case where audio finishes quickly but visuals fail; the strategy should clearly state whether to wait, retry, or stop.
No. Shared limits, resource contention, and coordination overhead can offset the benefit.
Not reliably when their timing must match the generated speech. Use the final audio or its reliable timing data.
That all required branch outputs are complete, valid, and belong to the intended job and content version.
