Long Video Generator with Free Credits for LinkedIn Ads: A Practical Workflow

LinkedIn ads often need more than a 15-second clip. Explainer videos, product demos, and storytelling formats require longer durations to convey value. But generating long videos can be expensive, especially when you're testing multiple ad variations. That's where a long video generator with free credits comes in. This guide walks you through a practical workflow using Van Gogh Studio (FreeVideoGenerator) to create long-form video ads for LinkedIn—without spending a dime upfront.

Why Use a Long Video Generator for LinkedIn Ads?

LinkedIn's audience expects professional, informative content. Short clips work for brand awareness, but longer videos (30–90 seconds) are better for tutorials, case studies, and product explanations. A dedicated long video generator lets you produce these assets quickly, without hiring a video editor or using complex software.

With Van Gogh Studio, you get 21 free signup credits—no credit card required. That's enough to generate a couple of standard videos (roughly 10 credits each) and test the workflow. If you need more, the platform offers flexible plans starting at $14.9/month.

Step-by-Step Workflow: Creating a Long Video for LinkedIn Ads

Step 1: Sign Up and Access the Long Video Feature

Go to freevideogenerator.io and create a free account. You'll receive 21 credits instantly. Navigate to the Long Video tool from the dashboard. This feature is designed for generating longer narrative or explainer videos beyond single short clips.

Step 2: Define Your Video Concept and Script

Before generating, outline your video's purpose. For LinkedIn ads, common formats include:

• Product explainer: 30–60 seconds highlighting features and benefits.
• Customer testimonial: 45–90 seconds with a narrative arc.
• How-to tutorial: 60–90 seconds demonstrating a process.

Write a concise script or bullet points. The more specific your prompt, the better the output.

Step 3: Craft a Detailed Prompt

In the Long Video tool, you'll enter a text prompt. Use descriptive language that includes:

• Setting: e.g., "modern office"
• Characters: e.g., "professional woman in business attire"
• Action: e.g., "explaining a chart on a screen"
• Tone: e.g., "confident, informative"
• Duration: specify desired length (e.g., "60 seconds")

Example prompt:

"A professional woman in a modern office explains a productivity app on a large screen. She gestures to charts showing increased efficiency. The tone is confident and informative. The video is 60 seconds long."

Step 4: Choose Model and Settings

Van Gogh Studio offers multiple AI models (Kling, Sora 2, Veo 3.1, Runway, etc.). Availability and parameters vary by model, so check the live model selector. For long videos, select a model that supports extended durations. Adjust resolution and aspect ratio to match LinkedIn's recommended specs (e.g., 1920x1080 for landscape, 1080x1920 for vertical).

Step 5: Generate and Review

Click generate. The video will be created using your credits. Review the output. If it's not perfect, you can regenerate with tweaked prompts. Remember, each generation uses credits, so refine your prompt before generating multiple times.

Step 6: Enhance with AI Video Studio (Optional)

Once you have your long video, you can polish it using the AI Video Studio. This tool offers 100+ effects, motion control, video extend, and upscaling. For LinkedIn ads, you might add a subtle zoom effect or upscale to 4K for better quality.

Step 7: Export and Upload to LinkedIn

Download the final video and upload it to LinkedIn Campaign Manager. Ensure it meets LinkedIn's ad specifications (file size, format, etc.).

Reusable Prompts and Parameter Tips

• For a product demo: "A close-up of a hand using a mobile app, with text overlays highlighting key features. Duration: 45 seconds."
• For a brand story: "Cinematic shots of a team collaborating in a bright office, with a voiceover about innovation. Duration: 90 seconds."
• Parameter tip: Use a 16:9 aspect ratio for desktop feed ads, and 1:1 or 4:5 for mobile. Check the model's supported resolutions in the selector.

Common Pitfalls to Avoid

• Vague prompts: Generic prompts like "make a video about our product" yield generic results. Be specific.
• Ignoring credit costs: Each generation uses credits. Plan your tests to avoid running out.
• Overlooking model limits: Not all models support long durations. Verify in the selector before generating.
• Skipping the script: A clear script ensures the AI understands the narrative flow.
