Vidéo IA

Short product clips are everywhere: a 5-second shot of a sneaker, a 3-second pour of a skincare serum, a 6-second unboxing. But most ecommerce ad placements need 15, 30, or even 60 seconds. Re-shooting is expensive, and manually looping looks cheap. That's where AI video extension comes in. In this guide, you'll learn how to take a short clip and extend it into a longer, natural-looking video in under 10 minutes using Van Gogh Studio's Video Extend feature.
You have three main options when you need a longer video:
For ecommerce, AI extend is the sweet spot: you keep your original footage's quality and branding, but get a longer video that holds viewer attention.
Here's a practical workflow using Van Gogh Studio's Video Extend tool. The whole process takes less than 10 minutes, including upload and generation.
Start with a clean, high-quality clip. It can be as short as a few seconds. Make sure the subject is well-lit and the motion is clear. If your clip is too dark or shaky, consider using the video upscaler first to improve quality.
Go to freevideogenerator.io and sign in. New accounts get 21 signup credits, so you can try this without a credit card. Once logged in, navigate to the Video Extend tool.
Decide how long you want the final video to be. For example, if you have a 5-second clip and need a 15-second ad, you'll extend by 10 seconds. The tool will generate the additional frames.
Van Gogh Studio gives you access to multiple AI models (like Kling, Sora 2, Veo 3.1, and more). For video extend, pick a model that handles motion well. You can also adjust parameters like resolution and aspect ratio. Note that availability and exact parameters may vary, so check the live model selector for the latest options.
Click the generate button. The AI will create the extended video, maintaining motion continuity from your original clip. This usually takes a few minutes. Once done, review the result. If it's not perfect, you can tweak the prompt or parameters and try again.
Once you're happy, download the extended video. You can now use it in your ads, social posts, or website. If you need to adjust the aspect ratio or add effects, consider using the AI Video Studio for further edits.
While Video Extend primarily works from the original clip, you can sometimes add a text prompt to guide the AI. Here are some tips:
For parameters, start with the same resolution and aspect ratio as your original clip to avoid cropping. If you need a specific output, like 9:16 for TikTok, you can set that, but the AI will adapt.
