Quick answers.
What is the best free AI avatar generator?
Synthesia's free plan gives 10 minutes of avatar video a month with a watermark. HeyGen's free plan gives 3 short videos a month. With an NVIDIA graphics card, InfiniteTalk is completely free with no watermark.
Is HeyGen free?
Partly. The free plan makes 3 watermarked videos a month, each up to 1 minute. Paid plans start at $29 a month, which buys about 19 minutes with the Avatar IV model or about 12 with the newest Avatar V.
HeyGen vs Synthesia, which is better?
HeyGen has the more lifelike avatars and makes a clone of you from a short phone clip. Synthesia is cheaper to start, gives more free minutes and suits company training videos.
Can I make a photo talk with AI for free?
Yes. Dreamina (ByteDance's OmniHuman) gives daily free credits, and D-ID has a 14-day trial. On your own PC, InfiniteTalk turns a photo and an audio file into a talking video at no cost.
Can I run an AI lip sync model offline on my computer?
Yes, with an NVIDIA card. MuseTalk runs on 4 GB of graphics memory, LatentSync needs 8 to 18 GB, and InfiniteTalk works best with about 16 GB. Macs are poorly supported for audio-driven avatars.
What is the best AI to lip sync an existing video?
For free, LatentSync from ByteDance gives sharp mouths on filmed faces with an NVIDIA card of 8 GB or more. InfiniteTalk can also re-dub a video and moves the head too.
