Native audio in a single generation
Both models generate sound together with the video, so there's no separate voiceover or music pass. HeyGen Video produces native audio straight from your prompt and lets you steer it with up to 12 reference images, videos, and audio. Veo 3.1 goes further on fidelity: synchronized dialogue, sound effects, ambient audio, and music at 48kHz stereo with lip-sync accuracy under 120ms. For prompt-driven sound with reference control, HeyGen Video leads; for broadcast-grade dialogue and music, Veo 3.1 leads.
768p with seven ratios vs native 4K
Veo 3.1 outputs native 4K (3840x2160) at selectable 24, 30, or 60fps with 16-bit HDR - the highest-quality output of the two - in 16:9 and 9:16. HeyGen Video outputs 480p or 768p but gives you far more framing freedom: seven aspect ratios including 21:9, 1:1, 4:3, and 3:4 plus an adaptive option. If maximum resolution and HDR matter most, Veo 3.1 leads; if you need lightweight clips in many aspect ratios, HeyGen Video leads.
References, first frames, and clip length
HeyGen Video gives you more inputs to direct a scene: a first-frame image to lock the opening shot, plus up to 12 reference images, videos, and audio you name in the prompt (Picture 1, Video 1), with clips from 5 to 15 seconds and a seed for reproducible takes. Veo 3.1 uses Ingredients to Video - up to 3 reference images for characters, objects, or scenes - and does not publicly specify a maximum clip length. HeyGen Video offers more reference headroom and length control; Veo 3.1 keeps references simple and focused on consistency.
