Why Wan AI costs more than Vidu Q1 when both give you 5 seconds
wan ai vs vidu q1 price
Wan AI costs 2,500 credits per generation, Vidu Q1 costs 2,000 — a flat 500-credit gap, so Wan AI is 25% more for the same 5 seconds. Each model in the price list carries its own per-generation figure. On the 100,000-credit pack ($39.99) that works out to $1.00 versus $0.80 per clip. Cheaper 5-second entries exist: Sora-2 Pro at 751 credits.
How this works
Each model carries its own price per generation
The intuition behind the question is that a clip's cost should scale with its length. In this price list it does not work that way. Each video model has one credit figure attached to one generation, and that figure is set per model. Wan AI is 2,500 credits. Vidu Q1 is 2,000 credits. Both entries describe a 5-second generation. The 500-credit difference is the price of the model you picked, and it is the same 500 credits on every run. Grok Video is listed with a per-second price is charged at 350 credits per second at 480p and 450 credits per second at 720p. The other entries below each show a single credit figure for a generation. So when two clips of identical length carry different charges, the variable to look at is the model name, not the length.
What each price line actually covers
Being precise about what you are buying matters more than the headline number. Wan AI at 2,500 credits is recorded as 720p, 5 seconds. Vidu Q1 at 2,000 credits is recorded as 5 seconds — resolution is not part of that price entry, so we will not quote a figure we cannot show you. That is the honest state of it. On audio, six entries in the list name sound as part of the package: Veo-3.1 Fast (1,500 credits, 8 s), Veo-3.1 Pro (2,000, 8 s), Kling v2.6 (3,500, 5 s), Hailuo H3 (3,375, 768p, 5 s), Seedance 2 Fast (6,200, 720p, 5 s) and Seedance 2.0 (7,750, 720p, 5 s). Separately, Seedance 1.5 and Kling V3 are offered in two variants each — audio off and + audio — where the audio-off variant costs close to half of the + audio one, which is a direct explanation for a silent result on those two. The Wan AI and Vidu Q1 lines are single figures per generation and do not name audio, so if sound has to be guaranteed by the price sheet, pick one of the six entries that names it.
The 500-credit gap converted to money
Credits only mean something once you know what you paid for them, and the rate depends on the pack. Doitong sells three: 30,000 credits for $19.99, 100,000 for $39.99, and 300,000 for $99.99 — roughly $0.67, $0.40 and $0.33 per 1,000. Per clip, Vidu Q1 lands at $1.33, $0.80 and $0.67 across those three packs. Wan AI lands at $1.67, $1.00 and $0.83. The gap per clip is $0.34, $0.20 and $0.16 respectively. That gap is small on one clip and loud on a batch. A hundred Wan AI generations burns 250,000 credits; a hundred Vidu Q1 generations burns 200,000. The 50,000-credit difference is larger than the entire 30,000-credit pack. If you iterate on prompts — where a lot of credits go to takes you throw away — the model you park on for drafting moves your bill more than the model you use for the final render.

The detail
Cheaper 5-second entries in the same list
If the requirement is genuinely "5 seconds of video," both of these sit mid-list rather than at the bottom. Sora-2 Pro is 751 credits for 720p, 5 seconds — the lowest 5-second figure in this list. Seedance 1.0 (lite 720p, 5 seconds) and Luma Fast (720p, 5 seconds) both sit at 1,200 credits. All three land under Vidu Q1's 2,000 and Wan AI's 2,500 for the same clip length. One trap worth naming: the names do not track the prices. Sora-2 Lite is 2,500 credits, well above Sora-2 Pro's 751. Luma Fast is 1,200 while Luma Pro is 3,550. Seedance 2 Fast is 6,200 against Seedance 2.0 at 7,750. "Lite," "Fast" and "Pro" are parts of the model name here, not price tiers — read the credit figure before you generate. Nothing on this page claims a cheaper entry produces output you will prefer; it tells you what you are charged, so you can decide where to spend the takes you discard and where to spend the one you keep.
Where duration does show up in the math
Duration works differently from a per-second meter: it varies between models and is fixed inside each one, so it changes what the flat price buys rather than driving the price up. Most entries in the list deliver 5 seconds. Veo-3.1 Fast and Veo-3.1 Pro deliver 8 seconds with audio included, at 1,500 and 2,000 credits. Hailuo 2.3 delivers 6 seconds at 1,400 credits. Grok Video is listed with a per-second price. Divide and the picture sharpens. Wan AI is 500 credits per second of output, Vidu Q1 is 400, and Veo-3.1 Pro — at exactly the same 2,000 credits as Vidu Q1 — is 250, because its line reads 8 seconds instead of 5 and names audio in the package. On the 100,000-credit pack that is $0.20, $0.16 and $0.10 per second of finished video. This is also the answer to "why does my clip stop at five seconds." Five seconds is what the entry you chose describes; an 8-second result comes from an entry whose line says 8 seconds.
Questions people ask next
Is Wan AI 25% better than Vidu Q1 because it costs 25% more?
Nothing in the price list encodes quality, and we will not invent a ranking. What the list does record: Wan AI is 2,500 credits with a 720p, 5-second entry; Vidu Q1 is 2,000 credits with a 5-second entry that does not specify a resolution. The price list says what each model charges — it is not a quality score. Judge the output by running both on the same prompt.
Which models include audio in the price?
Six entries name sound as part of the package: Veo-3.1 Fast (1,500 credits, 8 s), Veo-3.1 Pro (2,000, 8 s), Kling v2.6 (3,500, 5 s), Hailuo H3 (3,375, 5 s), Seedance 2 Fast (6,200) and Seedance 2.0 (7,750). Seedance 1.5 and Kling V3 additionally come in two variants each — audio off and + audio — where the audio-off variant costs close to half the + audio one, so a silent result on those two points straight at which variant was run.
What is the cheapest 5-second entry in this list?
Sora-2 Pro at 751 credits, recorded as 720p, 5 seconds. Next up are Seedance 1.0 (lite 720p, 5 s) and Luma Fast (720p, 5 s), both at 1,200 credits. All three sit below Vidu Q1's 2,000 and Wan AI's 2,500 for the same clip length. These are the figures for a normal generation.
How is resolution priced on Wan AI and Vidu Q1?
Their lines each show a single credit figure per generation — 2,500 and 2,000 — with resolution appearing only as a description (Wan AI is listed at 720p; the Vidu Q1 entry does not state one). Grok Video is listed with a per-resolution, per-second price: 350 credits per second at 480p versus 450 credits per second at 720p. For the other entries, the credit figure printed next to the model is what a generation costs.
Why does my video stop at 5 seconds?
Because 5 seconds is what the entry you chose describes — it is the model's listed output, not a truncation. Durations vary: 12 of the 17 listed models deliver 5 seconds, Hailuo 2.3 delivers 6, and Veo-3.1 Fast and Veo-3.1 Pro deliver 8 with audio included, at 1,500 and 2,000 credits. Grok Video is billed per second instead. A longer clip comes from an entry whose line states the longer duration.
How many credits do 100 clips cost on each model?
Wan AI: 250,000 credits. Vidu Q1: 200,000 credits. The 50,000-credit spread is larger than the whole 30,000-credit pack ($19.99). Per clip the difference is $0.34, $0.20 or $0.16 depending on which pack you bought — trivial on a single render, material once you count the takes you discard while iterating on a prompt.
Is Veo-3.1 Pro a better deal than Vidu Q1 at the same price?
They cost the same: 2,000 credits each, which is $1.33, $0.80 or $0.67 per clip across the three packs. What differs is the envelope. Veo-3.1 Pro's entry reads 8 seconds with audio included; Vidu Q1's entry reads 5 seconds. That is 250 credits per second of output against 400 — on the 100,000-credit pack, $0.10 per second versus $0.16. Whether the output suits your prompt is a separate question the price sheet cannot answer.
Do the names Lite, Fast and Pro tell me anything about price?
Not reliably. Sora-2 Pro is 751 credits while Sora-2 Lite is 2,500 — the "Pro" is the cheap one there. Luma Fast is 1,200 and Luma Pro is 3,550, so that pair does track cost. Seedance 2 Fast is 6,200 against Seedance 2.0 at 7,750. Treat the suffix as part of the model name and read the credit figure before you generate.
