Question 1

How do I use Veo 3.1 with n8n?

Accepted Answer

Kie AI doesn’t have a native n8n node, so I connect it with an HTTP Request node. The pattern is POST to start the video generation task, wait 30–60 seconds (sometimes longer), then GET the video details using the task_id. Once it returns success, I grab the results URL and use it however I want (view it, download it, save to Drive, etc.).

Question 2

Is Kie AI cheaper than using Google’s Veo API directly?

Accepted Answer

Yeah—this is one of the main reasons I’m using Kie AI in the first place. In the video, I call out that it’s significantly cheaper than using Google’s direct APIs. If you’re doing bulk generation, cost adds up fast, so the pricing difference matters.

Question 3

What are the three Veo 3.1 generation types you covered?

Accepted Answer

I cover text-to-video (just a prompt), image-to-video (one image or start + end frame), and reference-to-video (one to three images). In the API JSON, this is controlled by the generation type field. The workflows are basically the same in n8n—you’re mostly swapping the input payload.

Question 4

Why do my image-to-video generations fail or get rejected?

Accepted Answer

A big reason is copyrighted images. When I got lazy and used Google images, I saw a decent amount of failures, and that’s common. My recommendation is a two-tier approach: generate your own images with an image model first, then feed those into video generation.

Question 5

Can I generate vertical 9:16 videos with Veo 3.1 on Kie AI?

Accepted Answer

For text-to-video and image-to-video, you can choose 9:16 or 16:9. But reference-to-video is 16:9 only right now, and if you try 9:16 it’ll fail. If you need vertical ads, don’t build your workflow around reference-to-video until they add that ratio.

Question 6

How do I securely store my Kie AI API key in n8n?

Accepted Answer

Don’t paste your bearer token directly into the node, especially if you might share the workflow. I use a generic credential in n8n (Header Auth) and store the value as “Bearer {API_KEY}”. That way your key isn’t sitting in the node config for someone to steal.

Question 7

How do I scale AI video generation to create lots of videos automatically?

Accepted Answer

My favorite approach is a spreadsheet for bulk generation—drop 20–30 prompts in a Google Sheet and loop them through the workflow. A form trigger is also fine if you only need one video at a time. Once the core POST → wait → GET pipeline is built, scaling is mostly about what you connect on the left (inputs) and right (storage/editing).
