From a G2 user’s perspective, HeyGen is easy to use and produces realistic avatar video quickly, though limited free exports and watermarks can be a downside. Another reviewer created over 1,000 short-form videos in three months with fast processing and smooth quality.
Reddit users also highlight HeyGen’s ability to lip-sync translations convincingly, with one saying, “It not only translates the voice very similarly but also lipsyncs the person talking into the output language. It works great.” Some, however, report delays, usage limits, and support issues.
