How to choose an AI video generator
- What kind of video? Avatar, generative clip, edited footage, or voiceover — this is the biggest decision.
- On camera or faceless? Faceless favors Synthesia/HeyGen/InVideo; on-camera favors Descript/CapCut.
- Budget? CapCut, Luma, and free tiers cost nothing; avatar tools run $18–$30+/mo.
- Volume & languages? Synthesia for scale and localization; InVideo for high-volume social.
Most creators combine two — for example, InVideo or Synthesia for the video plus ElevenLabs for the voice.
Tips for better AI video
- Write a tight script first — AI video is only as good as the words.
- Keep generative clips short (a few seconds) and stitch them for best coherence.
- Add captions — most social video is watched on mute.
- Use a real AI voice (ElevenLabs) rather than robotic defaults.
- Always review for artifacts and factual errors before publishing.

Synthesia/HeyGen for avatars, Runway/Kling/Sora for generative clips, Descript for editing, InVideo for faceless social, and ElevenLabs for voice. Start with free tiers and build a two-tool workflow.
