Isn’t it enough to just put a inside the to have a video preview? What makes your service cost 5k?
@magamuga Facebook stopped video preview by 1 month, everyone knows this.
Cost is 5k because a big page could recover this money in 1 day using video cover.
I made 800$ per day with a page of 250k followers,making 3 posts. My solution worth the money.
I didn’t know that FB stopped that stuff. But still, they have documentation on their developer pages about video previews. https://developers.facebook.com/docs/instant-articles/design/videolink/
When it was available to all, we have tried on several pages, plus own page with 8m followers, but it had the almost same engagement with the other links.
