Questions
HeyGen or Synthesia for explainer and training videos?
Both turn a written script into a video with a realistic AI presenter, so you need no camera or studio. Synthesia stands out for training teams, with over 140 languages and videos you update by editing the text. HeyGen adds a digital twin of you and translates existing videos with the voice synced to the lips. Make the same one-minute script in each and show it to a colleague.
Can I make AI avatar videos without paying?
Among these picks, only Captions lists a free plan, and it edits videos you record rather than generating an avatar. HeyGen, Synthesia, Higgsfield and Tavus are paid. Budget for a monthly plan if avatar presenters are the goal. Check how many video minutes each plan includes, since that drives cost more than the headline price.
Should I film myself or use a digital twin?
Filming yourself costs nothing extra, and Captions trims pauses, adds captions and corrects eye contact afterwards. A digital twin in HeyGen or a replica in Tavus pays off when you need many versions of the same message. Tavus suits sales teams sending one video per prospect at scale. Record a short, clean sample in good light, since the replica copies whatever you give it.
How do I turn one video into several European languages?
HeyGen translates an existing video into other languages and syncs the voice to the lips. Synthesia renders the same script in over 140 languages, which suits training you keep in several markets. Captions can dub your own recordings into other languages. Ask a native speaker to check each version, because a stiff translation stands out more on video than in text.
Do I have to label AI-generated videos in the EU?
The EU AI Act requires you to disclose content that imitates real people, such as deepfakes, so viewers know it is synthetic. A short on-screen note or a line in the description covers most marketing uses. Get written consent before you clone anyone's face or voice, including staff. Keep the consent with the video files in case a platform or client asks.
