Frequently Asked Questions
- What is the cheapest AI video generator?
- CapCut starts at $15/month for video editing features. For text-to-video, typical pricing is around $30/month. Avatar generators like Synthesia and HeyGen start at $50/month.
- Can AI video generators create long videos?
- Avatar generators like Synthesia and HeyGen can create up to 30 minutes (typical 15 minutes). Text-to-video tools are limited to around 16 seconds maximum per clip.
- Do AI video generators support voice cloning or custom voices?
- Yes, most avatar generators like Synthesia and HeyGen offer voice cloning as an add-on or premium feature. You can upload a short audio sample (typically 3–5 minutes) to create a digital replica of your voice. Text-to-video tools like Runway generally do not include voice cloning—they focus on visual generation. If you need a consistent brand voice, look for plans that include custom voice training, which usually costs an extra $20–$50/month.
- Can I use AI-generated videos for commercial purposes like ads or YouTube monetization?
- It depends on the tool’s licensing terms. Most paid plans on Runway, Pika, Synthesia, and HeyGen grant full commercial rights for videos you create. However, free trials and basic tiers often restrict usage to personal or non-commercial projects only. Always read the fine print: some platforms require attribution (e.g., 'Powered by [Tool Name]') in commercial videos, while others prohibit use in certain industries like political advertising or adult content.
- What hardware or internet speed do I need to run these tools smoothly?
- All five tools listed are cloud-based, so you don’t need a powerful GPU locally. A stable internet connection with at least 10 Mbps download speed is recommended for smooth preview streaming. For uploading large video files (e.g., for editing in CapCut), 20 Mbps upload speed is ideal. Chrome or Edge browsers work best. No special hardware is required, though a modern laptop (2021 or newer) will handle the browser-based interfaces without lag.
