Converting print non-fiction work/series into video format

[I checked the forum archives, but only found material related to adaptation of fiction].

Currently, I am considering the conversion of a non-fiction print work/series into video format.

My questions are thus:

i) as an adaptation, would I need the publisher's approval/copyright license?;

ii) if one was to do a video production based on the book and its ideas, would
I need the publisher's approval/copyright license?;

Thanks,

Not sure why this question has been posted here, but the quick answer has to be, yes and yes. Whether material is fiction or non-fiction, someone owns it. It's theirs. Whatever your reasons for wanting to convert it into video format, whatever that means, you can't use the material without their permission.

Thanks. Video format here means taking the material/content, adapting, scripting and shooting if for a commercial sale-type industrial video,
perhaps tv style.

The advice is still a firm "no. don't do it."

I take it that you mean don't do it without obtaining a copyright license, rather than don't do it at all/even consider the idea.Correct?
