Modalities: HeyGen compared with Veo 3

Image Generation	No. Does not generate still images.	No. Veo outputs video with audio, not still images. Still generation in Flow is a different model.
Voice Mode	No. No voice interface.	No. There is no conversational voice loop; you type or attach a frame, then wait for a clip.
Video Understanding	Partial. Uploaded video is used for translation and lip-sync, not analysis.	Partial. Veo can extend clips and take frame direction in Flow/API. Analysing arbitrary uploaded video is Gemini video understanding, not Veo.
