Correction, 2026-10-02: this page quoted Veo 3.1 at 448 credits without saying that the Veo tool opens on Veo 3.1 Fast (168 credits for 8 seconds with sound); gave Kling's resolution only as "set by the model", although Kling v3 Standard returns 720p and Kling 2.6 Pro 1080p; said Sora workflows "usually" move to Seedance 2.5 and Veo 3.1, which we have no data on; and suggested drafting on Veo 3.1 Lite and Kling 2.6 Pro and then promoting "the winner" to other models, although a draft on one model does not show you what another model will make. It also left out the date the Sora app closed (2026-04-26) and Kling 4.0, announced on 2026-09-30 and not on 8frame. Prices now lead with what each tool opens on, and the advice is to give both models the same still.
Correction, 2026-10-01: an earlier version said Kling v3 on 8frame makes 16:9, 9:16 or 1:1 from text and suggested sending one text prompt to Veo and Kling v3 side by side. On 8frame, Kling v3 Standard and Pro are image-to-video only: they need a start image and follow its shape. Text-only Kling prompts go to Kling 2.6 Pro, and the comparison pass below now prices both routes.
If you searched "veo vs sora vs kling", the short version is that Sora 2 is retired: OpenAI closed the Sora app on 2026-04-26 and shut down the Sora 2 API on 2026-09-24, and 8frame no longer offers it for new generations. That leaves Veo 3.1 from Google and Kling v3 from Kuaishou. What you can check about them is length, shape, resolution, input, sound and price. Veo 3.1 makes 4, 6 or 8-second clips in 16:9 or 9:16 at 1080p (720p on Lite), from text or a start image; the Veo tool opens on Veo 3.1 Fast at 168 credits for 8 seconds with sound, Standard is 448 and Lite 54. Kling v3 makes 3 to 15-second clips, only from a start image, and takes that image's shape; the Kling tool opens on Kling v3 Standard at 86 credits for 5 seconds with sound (57 silent), and its files come back at 720p. Which one suits your shot is something to test on the same still, not something a table can settle.
Correction, 2026-09-30: the first version of this page described a May 2026 test with timings and per-run results that we cannot reproduce, listed Veo 3.1 as 4K at 60fps and Kling v3 as 4K at 30fps with three-minute clips, priced a 5-second Veo clip (Veo has no 5-second option) and a 30-second Veo piece at $5 to $7 (six 8-second clips are $26.88 at pack rate), said Seedance 2.5 was not on 8frame, and made claims about Runway and Sora we could not source. This version keeps only what we can verify.
TL;DR
| Veo 3.1 | Kling v3 | |
|---|---|---|
| Maker | Kuaishou | |
| The 8frame tool opens on | Veo 3.1 Fast: 168 credits for 8 s with sound | Kling v3 Standard: 86 credits for 5 s with sound |
| Lengths on 8frame | 4, 6 or 8 s (8 s from a start image) | 3 to 15 s |
| Resolution on 8frame | 1080p on Standard and Fast, 720p on Lite | No setting: v3 Standard returns 720p, Kling 2.6 Pro 1080p |
| Input on 8frame | Text, a start image, or a start and an end image | A start image is required (text only: switch to Kling 2.6 Pro) |
| Shapes | 16:9 and 9:16 | Follows the start image (Kling 2.6 Pro from text: 16:9, 9:16 or 1:1) |
| Sound | A setting, on by default; silent costs less | A setting, on by default; silent costs less |
| Other tiers | Standard 448 for 8 s with sound; Lite 54 (720p) | v3 Pro 114 for 5 s with sound; Kling 2.6 Pro 95, or 47 silent |
Sora 2 is retired, and this page does not recommend it. OpenAI closed the Sora app on 2026-04-26 and shut down the Sora 2 API on 2026-09-24; 8frame no longer offers Sora for new generations. Kling 4.0 was announced on 2026-09-30 in early access; it is not on 8frame, so everything below is about Kling v3.
Sora 2: what happened
OpenAI's deprecations page lists the Videos API and the sora-2 and sora-2-pro models as announced for deprecation on 2026-03-24 and shut down on 2026-09-24, with no replacement listed. OpenAI's help center says the Sora web and app experiences were discontinued on 2026-04-26. On 8frame, Sora is not available for new generations, so there is nothing left to compare it on: pick between the two models below. If you still have Sora videos, see what happens to Sora videos after the shutdown.
Veo 3.1 on 8frame
Veo 3.1 runs 4, 6 or 8 seconds. Veo 3.1 Standard and Fast output 1080p; Veo 3.1 Lite outputs 720p. It makes 16:9 and 9:16. From a start image it always runs 8 seconds, and with a start and an end image it animates between them, also at 8 seconds. Sound is a setting, on when the tool opens, and the tool opens on Veo 3.1 Fast.
| Veo tier | 4 s with sound | 4 s silent | 8 s with sound | 8 s silent |
|---|---|---|---|---|
| Veo 3.1 Fast (the tool opens here) | 84 | 56 | 168 | 112 |
| Veo 3.1 Standard | 224 | 112 | 448 | 224 |
| Veo 3.1 Lite (720p) | 27 | 17 | 54 | 33 |
On Google's own Gemini API, prices include audio: Veo 3.1 Fast is $0.12 a second at 1080p ($0.96 for 8 seconds, against 168 credits, $1.68 at pack rate, on 8frame), and Veo 3.1 Standard is $0.40 a second at 720p or 1080p ($3.20 for 8 seconds, against 448 credits). The API is cheaper per clip, and it offers 4K ($0.60 a second on Standard, $0.30 on Fast), which 8frame does not. See Veo 3 pricing explained.
Kling v3 on 8frame
Kling v3 runs 3 to 15 seconds. On 8frame it is image-to-video only: it needs a start image and takes that image's shape. There is no resolution setting; Kling v3 Standard files come back at 720p. Sound is a setting, on when the tool opens, and the Kling tool opens on Kling v3 Standard. For a text-only prompt, switch the node to Kling 2.6 Pro, which makes 16:9, 9:16 or 1:1 at 5 or 10 seconds and returns 1080p.
| Kling tier | 5 s silent | 5 s with sound | 10 s with sound |
|---|---|---|---|
| Kling v3 Standard (the tool opens here) | 57 | 86 | 171 |
| Kling v3 Pro | 76 | 114 | 227 |
| Kling 2.6 Pro (runs from text) | 47 | 95 | 189 |
Kling v3 Standard costs less per clip than Veo 3.1 Fast: 86 credits for 5 seconds with sound against 168 for 8. To compare equal lengths, set Kling v3 to 8 seconds: 137 credits with sound, 91 silent on Standard. For a square clip, start Kling v3 from a square image; Veo does not make square. Kling announced Kling 4.0 on 2026-09-30, in early access with a wider rollout in October; it is not on 8frame. More in Kling v3 pricing explained.
Where Sora 2 workflows can go
| What you used Sora 2 for | Where to move on 8frame | What you can check |
|---|---|---|
| Long single takes | Seedance 2.5 or Wan 3.0 | Both run up to 30 s in one generation: 30 s of Seedance 2.5 at 720p is 937 credits, sound included; Wan 3.0 at 1080p is 567 |
| Short shots with sound | Veo 3.1 Fast (the Veo tool's default) | 8 s with sound at 1080p, 168 credits |
| Cheap variants for ads | Kling v3 Standard (from a still) or Wan 3.0 at 480p | 57 credits for 5 silent seconds, and 24 for 5 s |
| Shots built from reference images | Seedance 2.5 (up to 9 references) or Kling O1 Reference (up to 7) | Reference-driven generation |
One thing to know before moving reference-heavy work to Seedance: in our tests in August 2026, reference images with a close-up face were rejected with error E005, while waist-up and full-length shots of the same person passed. See Seedance flagged as sensitive (E005).
Compare them on the same still
No table tells you which model suits your shot, so run it on both, side by side on the 8frame canvas, and judge the results yourself. Kling v3 needs a start image, so the fair test is one still and one motion prompt given to both:
- Make or upload the still in 16:9 or 9:16, the two shapes Veo makes; Kling v3 follows the image's shape.
- Connect it to a Veo node and a Kling node with the same motion prompt. Veo runs 8 seconds from a start image; set Kling v3 to 8 seconds too, so the lengths match.
- At the tools' opening settings, that is 168 credits for Veo 3.1 Fast and 137 for Kling v3 Standard at 8 seconds with sound: 305 for the pair. With sound off, 112 and 91: 203.
- Judge at the tier you would ship. If you plan to deliver on Veo 3.1 Standard or Kling v3 Pro, run that tier on the same still before committing: a draft on another tier is a different run and does not show you the final one.
Kling v3 cannot take part in a text-only comparison. From the same prompt, put Kling 2.6 Pro (95 credits for 5 seconds with sound, 47 silent) against Veo 3.1 Fast.
FAQ
Is Sora 2 still available?
No. OpenAI closed the Sora app on 2026-04-26, and its deprecations page lists the shutdown of the Videos API and the Sora 2 models on 2026-09-24. 8frame no longer offers Sora for new generations.
Which is better, Veo 3.1 or Kling v3?
We have not measured which looks better, and it depends on the shot, so test both on the same still. What you can check: Veo 3.1 runs 4 to 8 seconds at 1080p (720p on Lite) in 16:9 or 9:16 and starts from text or an image; Kling v3 runs 3 to 15 seconds, needs a start image on 8frame and returns 720p on Standard. At the tools' opening settings, Veo 3.1 Fast is 168 credits for 8 seconds with sound and Kling v3 Standard is 86 for 5 seconds.
What is the best Sora 2 alternative in 2026?
It depends on what you used Sora for. For long single takes, Seedance 2.5 or Wan 3.0 (both up to 30 seconds). For short shots with sound, Veo 3.1 (the tool opens on Fast, 168 credits for 8 seconds). For cheap ad variants from a still, Kling v3 Standard (57 credits for 5 silent seconds) or Wan 3.0 at 480p (24). Test your own shot before you move a workflow.
How do Veo 3.1 and Kling v3 compare on cost?
On 8frame, the Veo tool opens on Veo 3.1 Fast at 168 credits for 8 seconds with sound; Veo 3.1 Standard is 448. Kling v3 Standard is 86 for 5 seconds with sound. For a 30-second piece, six 8-second clips cost 1,008 credits ($10.08 at pack rate) on Veo 3.1 Fast and 2,688 ($26.88) on Standard; six 5-second Kling v3 Standard clips with sound cost 516 ($5.16).
Do Veo 3.1 or Kling v3 make 4K on 8frame?
No. On 8frame, Veo 3.1 Standard and Fast run at 1080p and Lite at 720p; Kling v3 Standard returns 720p and Kling 2.6 Pro 1080p. Google's Gemini API offers Veo 3.1 Standard and Fast in 4K. See AI video resolution by model.
Is Kling 4.0 on 8frame?
No. Kling announced Kling 4.0 on 2026-09-30 in early access, with a wider rollout in October. 8frame runs Kling v3 and older Kling models, which is what this page compares.
