A detailed guide on how to create a 40-second AI video with a single character using free tools and services, including tips on chaining clips and managing credits.
The exact free stack for 40-second AI video with one character, no editing: 1. Character first. Nano Banana Pro, image mode, one prompt. 0 credits. 2. Video on Veo 3.1 Lite, 16:9, one variant. 10 credits per 8-second clip. 3. Free tier gives 50 credits a day. That is five clips, which is 40 seconds. 4. Chain them with extend, not new generations. Extend continues from the last frame, so the character and scene hold. 5. Out of credits? Download, save the last frame as an image, open a new Google account, upload the frame, continue. 6. Change a detail in a finished shot with Gemini Omni Flash. 20 credits. 7. Free output is 720p with a "Made with Veo" watermark. Clean it after. No subscription anywhere in that list. The only real limit is 50 credits and your patience with retries.
