Where to Use FLUX 3 Video (Video to Video)

Video extension
Continue an existing clip seamlessly from its last frames.

Iterative editing
Refine or extend previously generated video without starting over.

Use cases

Video continuation: this model is documented for continuing an existing clip from its final frames, carrying momentum, framing, and scene logic into new footage.

Extending a shot: it is described as suitable for adding usable extra seconds to a shot without a hard cut, including extending an establishing shot to fit a longer edit.

Continuing camera movement: the documentation says it can continue a camera move past the end of the source footage, making it useful for motion that needs to flow beyond the original clip.

Creating alternate endings: it is also documented for generating alternate endings from the same input clip and story direction.

How to use FLUX 3 Video Video to Video API

Install any OpenAI-compatible SDK, point it at api.aimlapi.com/v1, and set the model to blackforestlabs/flux-3-video-v2v.
import requests, time

headers = {"Authorization": "Bearer " + AIMLAPI_KEY}
job = requests.post(
    "https://api.aimlapi.com/v2/video/generations",
    headers=headers,
    json={
      "model": "blackforestlabs/flux-3-video-v2v",
      "video_url": "https://example.com/clip.mp4"
    },
).json()
gid = job["id"]

while True:
    res = requests.get(f"https://api.aimlapi.com/v2/video/generations?generation_id={gid}", headers=headers).json()
    if res.get("status") in ("completed", "error"):
        break
    time.sleep(5)
print(res["video"]["url"])
const headers = {
  Authorization: `Bearer ${process.env.AIMLAPI_KEY}`,
  "Content-Type": "application/json",
};
const job = await (await fetch("https://api.aimlapi.com/v2/video/generations", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "model": "blackforestlabs/flux-3-video-v2v",
    "video_url": "https://example.com/clip.mp4"
  }),
})).json();

let res;
do {
  await new Promise((r) => setTimeout(r, 5000));
  res = await (await fetch(`https://api.aimlapi.com/v2/video/generations?generation_id=${job.id}`, { headers })).json();
} while (!["completed", "error"].includes(res.status));
console.log(res.video.url);
# submit the generation — the response contains the job "id"
curl -X POST https://api.aimlapi.com/v2/video/generations \
  -H "Authorization: Bearer $AIMLAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"blackforestlabs/flux-3-video-v2v","video_url":"https://example.com/clip.mp4"}'

# then poll until status is "completed" — video.url holds the result
curl "https://api.aimlapi.com/v2/video/generations?generation_id={id}" -H "Authorization: Bearer $AIMLAPI_KEY"

OpenAI-compatible — swap the base URL and it works with your existing SDK.
