Hi Hesham,
Thanks for reaching out! We designed our guide format with people’s attention spans in mind, so Dozuki helps authors reach the balance of providing informative instructions without overwhelming their readers. Three images or one video per step is a reflection of that, and if you need two videos in a step I recommend creating a new step for the second video, because it’s likely you’re describing two separate actions or concepts.
For more information about our recommended best practices, take a look at our [link|https://help.dozuki.com/Tech_Writing/chapter/7|Tech Writing Handbook chapter on using visuals].
