Cheapest AI video model on VdoBloom, measured in credits per second

"Cheapest" only means something once you fix the resolution and the length, because most models bill per second and roughly double their rate at each resolution step. A model that looks cheap at 5 seconds can be the expensive one at 15.

So here is the honest comparison: credits per second of output at 720p, read directly from VdoBloom's pricing table. At the bottom of the range ByteDance V1 Pro Fast Image-to-Video charges 1.4 credits per second at 720p, and P-Video, which also takes a text prompt, charges 1.6. At the top, Seedance 2.5 charges 25.2 credits per second for the same resolution — a roughly 18x spread inside the same platform.

If you are producing at volume — bulk product clips for a Flipkart or Meesho catalogue, ad variants, thumbnail loops — this single number is the one that determines whether the workflow is viable. Picking the right tier for drafts and the right tier for finals is worth more than any prompt trick.

What this tool does

  • Lowest per-second rate at 720p on both the text-to-video and image-to-video tabs: P-Video at 1.6 credits/sec, rising to 3.2 at 1080p.
  • Cheapest single 720p clip outright: ByteDance V1 Pro Fast Image-to-Video at 7 credits for 5 seconds (1.4 credits/sec) — but it is image-to-video only and offers just 5 and 10 second durations.
  • Credits per second at 720p: ByteDance V1 Pro Fast I2V 1.4 · P-Video 1.6 · Runway Gen-3 2.0 · Hailuo 2.3 Standard 2.5 (768P) · Grok Imagine Video 1.5 3.0 · Vidu Q2 Turbo 3.0 at 8s · Seedance 2 Mini 3.3 · PixVerse v4 4.0 · WAN 2.6 Flash 4.0 · Kling 3.0 std 6.0 · WAN 2.7 6.4 · Kling V3 Turbo 8.1 · PixVerse V6 9.0 · Seedance 2 16.4 · Seedance 2.5 25.2.
  • A 10-second 720p clip on ByteDance V1 Pro Fast Image-to-Video costs 15 credits.
  • Seedance 2 Mini includes native audio at no surcharge: 8 credits for 5 seconds at 480p, 17 at 720p.
  • Stepping from 720p to 1080p roughly doubles cost on most models — P-Video 1.6 to 3.2 credits/sec, ByteDance V1 Pro Fast I2V 1.4 to 3.0.
  • Seedance 2 Mini costs about 3.3 credits/sec at 720p and 1.6 at 480p.
  • Veo 3.1 is flat-priced at 25 credits (Fast) or 100 (High Quality) with no duration or resolution dial, so a short draft costs the same as a full clip.
  • The most expensive per-clip video-model configuration is Seedance 2 at 4K: 333 credits for 4 seconds and 1,248 credits for 15 seconds. Avatar and lip-sync jobs are priced by input length and can run higher — Kling AI Avatar Pro reaches 2,424 credits at 1080p for 300 seconds.
  • Two cheap routes to sound: Seedance 2 Mini generates audio by default at about 1.6 credits/sec at 480p and 3.3 at 720p, and WAN 2.6 Flash carries audio on by default at 4 credits/sec at 720p (20 credits for 5 seconds) across a 2-15 second range.

How it works

  1. 1.Fix your resolution before comparing anything

    Rates are quoted per resolution tier and roughly double at each step. Decide whether the clip ships at 480p, 720p or 1080p first — comparing a 480p rate against a 1080p rate is how people conclude the wrong model is cheap.

  2. 2.Use the per-second models for drafts

    P-Video (1.6 at 720p), Grok Imagine Video 1.5 (1.5 at 480p) and Seedance 2 Mini (about 1.6 at 480p) all bill by the second. Only Grok Imagine Video goes below 4 seconds — it steps from 1 to 15 seconds — while P-Video and Seedance 2 Mini start at 4 seconds, which is 7 credits on Seedance 2 Mini at 480p. Fixed-duration models force you to buy 5 or 10 seconds whether you need them or not.

  3. 3.Keep audio off until the visuals are approved

    Audio is not free on every model: Kling 3.0 standard goes from 6.0 to 9.1 credits/sec with sound on. Generate silent drafts, lock the motion, then re-render once with audio — or pick a model where sound is included, such as WAN 2.6 Flash at 4 credits/sec at 720p or Seedance 2 Mini at 17 credits for 5 seconds at 720p.

  4. 4.Batch your drafts at 480p

    For catalogue or ad-variant work, run every concept at 480p first. Ten 4-second concepts on Seedance 2 Mini at 480p cost 70 credits total — less than one 5-second 720p clip on Seedance 2 (82). Only the winners get rendered at delivery resolution.

  5. 5.Re-render the winners, do not upscale blindly

    Once a concept is approved, re-run the identical prompt at 720p or 1080p on the same model so the motion is reproduced. Topaz Video Upscale is available at 3.2 credits/sec for 1x and 2x with a 30-credit minimum, which is worth it for a take you cannot risk regenerating.

Frequently asked questions

What is the cheapest AI video model on VdoBloom?

ByteDance V1 Pro Fast Image-to-Video has the lowest per-second rate at 720p, 1.4 credits/sec (7 credits for 5 seconds); it is image-to-video only with 5 and 10 second durations. If you need a text prompt or a flexible length, P-Video is 1.6 credits/sec at 720p, and Seedance 2 Mini makes a 4-second 480p clip for 7 credits at any length from 4 to 15 seconds.

Is there anything cheaper for a single short clip?

Yes, if you are working from an image and 5 seconds is enough. ByteDance V1 Pro Fast costs 7 credits for 5 seconds at 720p. It is image-to-video only and restricted to 5 and 10 second durations, so they are less flexible than Seedance 2 Mini, which runs any length from 4 to 15 seconds from 7 credits.

Why does the same model cost different amounts for the same length?

Resolution and audio. Most models roughly double their rate at each resolution step — P-Video goes from 1.6 credits/sec at 720p to 3.2 at 1080p — and on models with a priced sound toggle, such as Kling 3.0, audio adds more. A 10-second Seedance 2 Mini clip is 16 credits at 480p and 33 at 720p, so resolution alone roughly doubles it.

Which cheap model still gives me sound?

Two routes. Seedance 2 Mini generates audio by default at no surcharge, so a 4-second 480p clip with sound costs 7 credits. WAN 2.6 Flash generates native audio by default: it is image-to-video only, runs 2 to 15 seconds, and costs 4 credits/sec at 720p — 20 credits for 5 seconds and 40 for 10. Seedance 2 Mini sits below MiniMax H3's 4 credits/sec at 768P, and WAN 2.6 Flash matches it, for comparable audio-carrying output.

What does Seedance 2 Mini cost?

Seedance 2 Mini costs 1.6 credits/sec at 480p and about 3.3 at 720p — 8 credits for a 5-second 480p clip and 17 at 720p. That is its standard rate, and the cost for your exact duration shows before you generate.

How do I keep costs down for bulk product or catalogue videos?

Draft every concept at 480p on Seedance 2 Mini, which makes a 4-second test 7 credits, then re-render only the approved ones at 720p. For image-driven listing clips specifically, ByteDance V1 Pro Fast Image-to-Video at 7 credits per 5-second 720p clip lets you produce a large catalogue before spending anything on a hero render.
