Generate All Segments of an Episode at Once

Quick answer: In the episode editor’s top bar, next to Composite, Generate all appears while some segments have no clip. It shows the total price; press it and a dialog lists how many segments will be generated, their total seconds and the model, plus what is left out. Press Generate and the segments are submitted one by one, each charged at its own price tag and refunded if it fails. Segments beyond your concurrency limit wait in line and start by themselves.

Before pressing, pick the model in the top bar: every segment in the batch uses it. On Wan 3.0 · 480P a segment costs 10 credits per second.

What Generate all does

The episode timeline: every segment as a card with its thumbnail and duration
The episode timeline: every segment as a card. Generate all submits the ones that have no clip yet.

The dialog

Titled Generate all segments, it shows the count, the total seconds and the model — for example “8 segments · 96 s in total · Wan 3.0 · 480P” — and the total in credits, which is the sum of the price tags on those segments’ own buttons. The note underneath: Each segment is charged on its own and refunded if it fails. Segments beyond your concurrency limit wait in line and start automatically.

While it submits

After Generate, the dialog counts Submitting 3/8…. Stop here stops submitting the rest; the ones already submitted carry on. When it finishes you see 8 segments submitted; if some could not be submitted, the message gives how many and the first reason only, so look along the timeline for the cards that still have no clip.

On the website, a segment you wrote or edited yourself is checked for shots with no linked characters. When one has them, you are asked about that segment alone, with the same question as a single Generate: confirm and it is submitted; cancel and only that segment is skipped (Segment N was skipped: some shots have no linked characters.) while the rest carry on. The apps do not ask. Shots with no linked characters.

If a segment’s dialogue is not in the project’s dialogue language, you are asked once; your answer applies to the rest of the batch. Dialogue language check.

Credits

Before submitting anything, the total is checked against your balance. If it does not cover the total, the buy-credits window opens and nothing is submitted — no half-finished batch to sort out. If the balance runs out part-way (for example because something else was charged meanwhile), submitting stops at that segment and the buy-credits window opens. Each submitted segment holds its own credits and is charged when its clip arrives, refunded if it fails. What one segment costs.

Queue and time

Your account runs a limited number of generations at once, set by your plan. The rest wait in line with their credits held and start by themselves as slots free up; you can close the page. A long episode takes a while — each clip usually takes several minutes. Generating many segments at once.

On a phone

Generate all sits in the bottom bar, above Composite, with its price. The same dialog opens.

FAQ

Does it regenerate segments I already have?

No. Only segments without a clip. Use a segment's Regenerate button to redo one.

Can I use different models for different segments?

Not in one batch; it uses the model selected in the top bar. Generate the odd one out with its own button after switching models.

What if I close the page?

Submitted segments keep going. Submitting stops if you leave while the dialog is still counting.

Is it cheaper than one by one?

No, and not more expensive: the total is exactly the sum of the segments' own prices.

Fill the timeline in one go

One dialog, one total, and every segment refunded if it fails.
