Book Cover Image: We recommend a 400pix (w) by 600pix (H) image.
Images inside a book: The real aspect ratio and size in terms of W by H depends on where you are placing the image. However, we do have a maximum 10 Mega Bytes limit for each image.
Videos inside a book: There is no limit for videos which you link to when they are placed in streaming facilities such as YouTube or Vimeo. However, if you are adding a video to the book to make it available offline, we need to be quite mindful of sizes. Here are some factoids:
- Currently, there is no limit on the volume or size of a video file that you can add.
- Any video that you add to a book will increase size of the book which might impact its download speed or occupancy your scarce memory resources, especially if your Tablet or Phone is short of memory.
- Video rich content impose an extremely high cost on KNiTO infrastructure for content delivery. So, we do recommend keeping these as light as possible and only for when offline viewing of a topic is essential. Try to resort to images and descriptive text accompanying your shortened video.
- We do have a policy of reducing publishers royalty for video rich content. Please see this for more information.
