Doesn't sound very different from Grandma's recipe cards in terms of information density, potentially harder to follow if you have to deal with video playback. Recipe blogs also have compressed instructions, so it's not like you need to read all the fluff, but when first stumbling upon a recipe, a short video is definitely better at grabbing your attention and showing you the major points and the result, in a way that traditional blogs and cooking sites fail to replicate. Video is also better for conveying technique, but I prefer paper or cards while cooking something that's not completely new to me, for fewer handwashing interruptions.
