ePub heavy file size, is there a limit?

[marcellof7407236]

Hi Everyone

I’m working in InDesign CC 2017 on a digital magazine. My clients have many contents and many videos to put in.

I had to export my publication in epub 3.0 and moving it on an iPad. The tablet will work offline in desk mode inside my client stand.

I'm scared that epub file, with many images and many videos inside, will be too heavy and will not display properly on iPad and transition/animation will be jerky.

Is there a file size limit to export interactive epub properly? A great dimension file may have problems loading video and media for example?

I really appreciate any help. Thanks!

I'm working on a fixed layout epub right now that's more than 300 MB. Lots of videos and because it's going to be used on a 12" iPad Pro, I'm exporting PNG images at 300ppi.

Working fine so far. All I can tell you is that testing is essential.
