FAQ
Frequently asked questions
Can I create video ads without appearing on camera?
Yes. Both Synthesia and HeyGen let you create professional spokesperson videos using AI avatars — no camera, studio, or actor required. You type a script, choose an avatar, and the platform generates a broadcast-quality video in minutes.
What is the difference between Synthesia and HeyGen?
Synthesia is best for polished, multilingual spokesperson content — it supports 130+ languages and is ideal for product explainers and international campaigns. HeyGen excels at UGC-style realism and lip-sync accuracy, and its Video Translate feature can dub existing videos into 40+ languages. For most performance marketers, HeyGen is the better choice for paid social, while Synthesia suits YouTube and Connected TV.
What does Opus Clip do differently from Synthesia and HeyGen?
Opus Clip does not generate new video — it repurposes existing long-form content. It uses AI to identify the most engaging moments in a video, clips them into short-form segments, adds captions, and reframes for vertical formats. It is the right tool if you already have video content (demos, webinars, brand videos) that you want to turn into a library of short-form ad clips.
How much do these AI video tools cost?
Opus Clip starts at $19/mo with a free watermarked tier. HeyGen starts at $29/mo with a limited free tier. Synthesia starts at $29/mo with no free tier. Creatify starts at $33/mo with a free tier of 10 credits per month. All four offer significant cost savings compared to traditional video production.
Are AI avatar videos effective as paid social ads?
Yes, particularly for direct-response formats. UGC-style AI avatar ads from HeyGen and Creatify routinely perform on par with real UGC content in Meta and TikTok campaigns, especially for product explainers and testimonial-style ads. The key is a strong script -- the AI delivers the performance, but the copy still drives conversion.
What is Creatify and how is it different from HeyGen?
Creatify is purpose-built for DTC and ecommerce brands that need to produce and test large volumes of video ad variants. Its URL-to-Video feature turns any product page into a video ad in minutes, and its batch generation can create up to 50 variants at once. HeyGen is stronger for custom avatar realism and video translation. Creatify is stronger for high-volume ad creative production and has a built-in ad launcher for Meta, TikTok, and AppLovin.
What is Runway and how does it differ from Synthesia and HeyGen?
Runway is a generative AI video platform -- it creates video from text prompts or reference images rather than using AI avatars or repurposing existing footage. Its Gen-3 Alpha model produces cinematic, photorealistic short clips (up to 10 seconds) that are ideal for hero brand video, lifestyle product shots, and visual concept testing. Unlike Synthesia and HeyGen, Runway does not use avatars or require a script delivery -- it generates the visual content itself. It starts at $15/mo on a credit-based plan, making it the lowest entry price in the category.
