Kling v3 (Kuaishou's Kling VIDEO 3.0, sold by most hosts as "Kling 3.0") is priced per second almost everywhere, and a 5-second Standard clip with sound costs between $0.63 and about $1.63 depending on the host: fal $0.63, Runway's API 65 credits ($0.65), Replicate $1.26, and 8frame 86 credits (about $0.86 at the top-up rate, $1.40 on the $49 Creator plan, $1.63 on the $19 Starter plan). The same clip in Pro is $0.84 on fal, 85 Runway credits ($0.85), $1.68 on Replicate and 114 credits on 8frame. Without sound every host charges about a third less. Every number is from the vendor's own page, checked 2026-10-21.
Three switches that change the price
Sound. Every host in the table charges more with audio on. fal: Standard "$0.084 (audio off) or $0.126 (audio on)" per second, Pro $0.112 or $0.168. Replicate: Standard $0.168 or $0.252, Pro $0.224 or $0.336. Runway's API: Standard 9 or 13 credits per second, Pro 12 or 17. On 8frame a 5-second Standard clip is 57 credits silent and 86 with sound, Pro 76 and 114. Sound is on by default on the 8frame Kling node.
Voice control. fal charges more when voice control is used while generating audio: "$0.154" per second on Standard and "$0.196" on Pro. 8frame does not offer voice control on Kling v3.
4K. Replicate prices a 4K variant at $0.42 per second with or without audio; Runway's API lists kling3.0_4k at 43 credits per second; fal lists a Pro 4K endpoint without a price on the page; Kling's own credit guide says 4K output runs "at 30 credits per second". No video model on 8frame outputs 4K, Kling v3 included.
Kling v3 on 8frame is image-to-video only
On 8frame, Kling v3 Standard and Pro run through fal's image-to-video endpoints and need a start image: a text-only prompt on the Kling node has to switch to Kling 2.6 Pro (95 credits for 5 seconds with sound, 47 silent). Kling v3 Standard returns 720p on 8frame. Lengths run from 3 to 15 seconds, billed per second. If you are planning a text-to-video workflow, price Kling 2.6 Pro or another model; if you already have the frame, Kling v3 is the default. Upload rules for the start image are in Kling image-to-video upload requirements.
The price table
USD from each vendor's own page, checked 2026-10-21, for a 5-second clip unless stated. Per-clip totals for per-second hosts are rate x 5, for example fal Standard with audio: 5 x $0.126 = $0.63. We have not compared outputs across hosts; this page compares prices and published limits only.
| Host | Published unit price | Standard, 5 s, sound | Standard, 5 s, silent | Pro, 5 s, sound | Pro, 5 s, silent |
|---|---|---|---|---|---|
fal (kling-video/v3/{standard,pro}/image-to-video) |
Standard $0.084 / $0.126 per second (off / on); Pro $0.112 / $0.168; voice control $0.154 / $0.196 | $0.63 | $0.42 | $0.84 | $0.56 |
Runway API (kling3.0_standard, kling3.0_pro) |
Standard 9 / 13 credits per second (no audio / audio); Pro 12 / 17; "$0.01 per credit" | $0.65 | $0.45 | $0.85 | $0.60 |
Replicate (kwaivgi/kling-v3-video) |
Standard $0.168 / $0.252 per second (without / with audio); Pro $0.224 / $0.336; 4K $0.42 | $1.26 | $0.84 | $1.68 | $1.12 |
| Krea (plan units) | "Kling 3.0, 3s, standard mode, audio off": ~107 videos on Pro ($35 a month, $21 yearly) | Not listed | About $0.33 per 3 s clip monthly, $0.20 yearly | Not listed | Not listed |
| Magnific (plan credits) | "Kling 3.0 Pro 1080p": "450 credits/5s"; Premium €12 a month billed annually, 240K credits a year | Not listed | Not listed | About €0.27 per 5 s (audio not stated) | Not listed |
| 8frame (via fal) | 86 / 57 credits per 5 s Standard (sound / silent); 114 / 76 Pro | 86 credits ($0.86 top-up, $1.40 Creator, $1.63 Starter) | 57 ($0.57, $0.93, $1.08) | 114 ($1.14, $1.86, $2.17) | 76 ($0.76, $1.24, $1.44) |
Two readings. fal and Runway's API land within one to four cents of each other on every cell. Replicate's per-second rates are exactly double fal's on all four, so the same clip costs twice as much there.
Kling's own app
Kling sells memberships rather than per-clip API prices on the page we checked. Its credit guide lists Standard at $6.99 for the first month and $8.80 at renewal for 660 credits a month, Pro at $25.99 and $32.56 for 3,000, Premier at $64.99 and $80.96 for 8,000, and Ultra at $127.99 and $159.99 for 26,000; the lower figures are "first-subscription discount only". The same page prices 4K at 30 credits per second but prints no per-second figure for Standard or Pro, so we have left the app out of the table rather than guess.
What it costs on 8frame
The Kling node opens on Kling v3 Standard, 5 seconds, sound on: 86 credits. Every length is billed per second:
| Length | Standard, sound | Standard, silent | Pro, sound | Pro, silent |
|---|---|---|---|---|
| 3 s | 52 | 35 | 69 | 46 |
| 5 s | 86 | 57 | 114 | 76 |
| 10 s | 171 | 114 | 227 | 152 |
| 15 s | 256 | 171 | 341 | 227 |
On Starter ($19, 1,000 credits) that is eleven 5-second Standard clips with sound a month, or seventeen silent; on Creator ($49, 3,000 credits) thirty-four or fifty-two. A failed generation is refunded automatically. The full 8frame breakdown is in Kling 3 pricing explained, and every 8frame video rate per second is in AI video generator price per second.
So the API route is cheaper per clip, and the reason to run Kling v3 on 8frame is the board: generate the start frame with an image model, animate it in Kling v3, and put a Seedance 2.5 or Veo 3.1 take next to it from one balance. That side-by-side is in Kling v3 vs Seedance 2.5.
