Best for

Best for batch talking-head videos without showing your own face, corporate training, and multilingual export. Core loop: avatar + script + one-click generation.

Steps

Pick a tool

2 min

Tencent Zhiying / HeyGen / D-ID

Tencent Zhiying (most China-friendly, strong Chinese, generous free credits); HeyGen (best quality, 95%+ lip sync, ~$1-2/min); D-ID (cheap and sufficient, ~$0.3-0.7/min). Advanced: record 2-5 minutes of yourself and train an 'Instant Avatar' in HeyGen to clone your own presenter.

Prepare the avatar

2 min

Preset avatar / headshot photo

Start with a platform preset, or generate a custom presenter from a headshot (even lighting, clean background, ≥720p resolution).

Write the talking-head script

5 min

ChatGPT / Claude

100-300 words, short sentences with plenty of commas. Avatar lip sync is driven entirely by punctuation — the more standard your punctuation, the better the result.

Generate and render

5-10 min

HeyGen / Tencent Zhiying

Paste the script, pick a voice, submit the render (a 1-minute video takes about 1-2 minutes). Then check lip sync, expression and voice fit.

💡Play each segment and check the lips; re-render only the sentences that fail rather than restarting the whole video.

Post-process and publish

5 min

CapCut

Add captions, BGM and transitions in CapCut, then publish. For multilingual export, use HeyGen's multilingual lip sync to produce every language version from one script.

Pitfalls to avoid

Too few punctuation marks → lips out of sync

Lip sync depends on punctuation. Always split long sentences, add commas, and use periods to make the avatar stop and pause.

Free avatars look like 'mannequins'

Free-tier presenters have stiff motion. For real quality, pay for a tier or upload a cloned video of yourself.

Licensing and watermarks

Some free tiers watermark output or restrict commercial use. Confirm the license before bulk commercial publishing.
