Compression for reducing file size to play on iPad

Good Afternoon, Nick.

Storyline's compression during publish is pretty darn efficient, so I doubt you'd gain much by compressing your audio/video before bringing it into Storyline, particularly if you adjust Publish Quality to reduce file size.

Please let us know if you need anything else.  Thanks!

Thanks, Justin. The reason I ask is because I assumed the same thing was true for graphics. But in our extensive testing, we found that wasn't the case.

We created a 15 minute course that included about 100 large raw JPEGs (5 MB+ each) and then created the same course using GIMP to crop and scale the images outside of Storyline before inserting into the .story. Our results were amazing. We took a 60 MB+ published output zip file down to less than 17 MB just by scaling and cropping before bringing in.

I guess what I'm asking is if we were to insert only mp3s, rather than WAV or the like, would that serve any good? Would Storyline further compress the mp3s we inserted? Or would the published mp3 output be roughly the same size as what we originally put in?

Thank you!

Nick

Hello again, Nick.

My testing shows that your scenario wouldn't add much efficiency:

• Here is a .story project file (6 MB) that contains a 42 MB WAV file.  The resulting published output is 2 MB (even less zipped).
• Here is a .story project file (6 MB) that contains an 8 MB MP3 file.  The resulting published output is 2 MB (even less zipped).

Please let us know if you need anything else.  Thanks!

Thanks so much, Justin! I really appreciate your help.

Hi there Nick,

Just wanted to pop in and apologize for the subscription issue. We had it working in the past, but we had to implement a moderation feature that would cut down on the number of spam posts on the forums. When we put that new system in place, it caused an issue with automatic subscriptions. 

When you respond to a new thread, you'll need to manually resubscribe to a thread. I know it's not very user-friendly and again I'm sorry for the trouble. Hopefully we'll have this back up and working normally soon :)

Thanks and have a great day!
