ChatGPT describes old photos very well but does not turn them into video. The Incarn app does it inside the conversation: attach a portrait, ask for an animation, and a before and after player appears about two minutes later.
See examples of animated ancestors before you start.
Set it up
1Create an API key on your Incarn developer page.
2In ChatGPT, open the apps directory, search for Incarn and add it.
3On the Incarn authorization page, paste your key.
4Attach a photo and write, for example: animate this photo of my great-grandmother.
Ideas of automations
Bring a portrait to life while you research your family history with ChatGPT.
Animate several old photos one after another in the same conversation.
Price
Each animation uses 1 credit from your Incarn account: credit packs from €1.99 a photo down to €0.80, with no subscription, or developer plans from €19 a month excl. VAT. Videos come back in HD, without a watermark.
