Creating a full-length course video is a heavy lift. You need to script, record, edit, and keep learners engaged. If you're a course creator, you've probably wished for a faster way to turn your existing product pages or blog posts into video lessons. That's where a long video generator that works from product URLs can help. Instead of starting from a blank timeline, you can feed a URL into an AI tool and get a structured video that you can refine.

In this guide, I'll show you a practical workflow using Van Gogh Studio (also known as FreeVideoGenerator) to turn product URLs into long-form course content. You'll learn the steps, get reusable prompts, and avoid common mistakes.

Why Use a Long Video Generator for Courses?

Most AI video tools are built for short clips—5 to 15 seconds. That's fine for social media, but not for a course module. A long video generator lets you create a cohesive narrative that can run for minutes, which is closer to what learners expect.

When you use a product URL as the source, the AI can pull in key points, features, and benefits from your existing content. That saves you from writing a script from scratch. You can then add your own voiceover or use the platform's AI avatar to present the material.

Step-by-Step Workflow with Van Gogh Studio

Here's how to go from a product URL to a long-form course video.

Step 1: Prepare Your Source URL

Start with a page that has clear, structured content. A product page with headings, bullet points, and a description works best. If you have a blog post or a landing page, that's also fine. The AI will extract the main points, so make sure the page is not cluttered with unrelated text.

Step 2: Access the Long Video Feature

Go to the Long Video page on Van Gogh Studio. If you don't have an account, you can sign up for free—new accounts get 21 signup credits, no credit card required. That's enough to test the workflow.

Step 3: Input Your Product URL

In the Long Video interface, you'll see an option to paste a URL. Enter your product page link. The platform will analyze the content and generate a video outline. You can then adjust the script, add or remove sections, and set the duration.

Step 4: Choose Your Presentation Style

You have options: use an AI avatar to present the content, or use text overlays and stock footage. For a course, an avatar can be more engaging. Check the AI Avatar page to see available avatars and customization options. You can also use the AI Video Studio to add effects, motion control, and other enhancements.

Step 5: Generate and Review

Once you've set your parameters, generate the video. The platform will process your request. Keep in mind that generation time and credit cost depend on the model, duration, resolution, and output type. Typical standard usage is about 10 credits per video, but it can vary. After generation, review the video. You can extend or upscale it if needed.

Step 6: Edit and Refine

You can use the video editor to trim sections, add captions, or insert additional clips. If you need to make changes to the script, you can regenerate with new prompts. The goal is to get a polished draft that you can finalize.

Reusable Prompts and Parameter Tips

When using the Long Video feature, you can provide additional instructions to shape the output. Here are some prompts you can adapt:

For a course introduction: "Create a 3-minute introduction that explains the main problem this product solves, the target audience, and the learning objectives."
For a feature breakdown: "Generate a 5-minute segment that covers the top 5 features of this product, with a clear explanation of each feature and its benefit."
For a conclusion: "Write a 2-minute conclusion that summarizes the key takeaways and includes a call to action for the viewer to try the product."

Parameter tips:

Duration: Set the total length based on your course module. Start with 5–10 minutes and adjust.
Aspect ratio: Choose 16:9 for standard course videos.
Model selection: The platform offers multiple models (Kling, Sora 2, Veo 3.1, etc.). Availability and parameters change, so check the live model selector for current options.

Common Pitfalls to Avoid

Using a cluttered URL: If the page has too much unrelated content, the AI may include irrelevant points. Use a clean, focused page.
Ignoring credit costs: Long videos consume more credits than short clips. Monitor your credit balance and plan accordingly.
Skipping review: AI-generated videos can have errors. Always review and edit before publishing.
Expecting unlimited generation: Unlimited generation is only available on certain plans and during specific windows, and only for selected models and parameters. Check the pricing page for current details.
