I need video without filming anything

You need video output — demos, training, social clips — but you don't have a filming setup, a presenter, or a video editor.

If you have a script and need a presenter → Synthesia fits. If you have written content to repurpose → Pictory fits.

Synthesia

Fits if you need AI avatars reading a script — training videos, demos, corporate content.

Pictory

Makes more sense if you want to convert existing blog posts or scripts into video automatically.

NoteBoth tools produce recognizable AI video. If authenticity is important to your audience, factor that in.
