WHICH ONE TO PICK
Both have their place.
PICK VIDELY WHEN
- You want to show your product UI in motion, not a presenter talking about it
- You're shipping SaaS launches and need a video for landing pages, App Store, and X
- Your changelog needs a weekly motion-designed announcement video
- Your brand voice is product-led, not corporate-explainer
- You don't want an AI avatar in your launch video
PICK SYNTHESIA WHEN
- You're producing employee training, HR onboarding, or compliance videos
- You need the same script localised into 20+ languages with native voice-overs
- A presenter talking on camera is core to the format
- You want a consistent avatar persona across every video you ship
- Your audience is internal-comms or B2B-corporate, not consumer-facing product
