Publishing Quality options change?
Jul 07, 2022
I noticed that the publishing quality options in Storyline have changed. Instead of "image quality," it says "jpeg quality."
What does this mean? I generally use pngs rather than jpegs, so does the jpeg quality apply to them? Why narrow the quality option to jpegs specifically?

This worries me too. Lets do some tests.
So i did a test with an image to check whether the blurring issue with PNGs is solved or Articulate just choose a quick route out of the issue and changed the name in the publishing window ;-) You never know...

Both the png and jpg image look fine when published. We should test with other images too though as im not 100% sure whether my image is the best choice. In editmode in Storyline they look good too... only in Storyline preview mode they look blurry. I can imagine some people find that a nuissance... i dont mind, i always publish to test.
Adding the .story if anyone want to test with another settings or images...
Thanks for doing some testing, Math!
I would like someone from Articulate to comment on the change from "image" quality to "jpeg" quality. I also noticed that now 100% is the default for jpeg quality, whereas it used to be 80%. If you change the slider to 80%, it still says 100% (screen shot below).
I published the story file at "80%" quality, and it looks exactly the same as Math's 100% version, to me:
Tracy's 80% version: https://360.articulate.com/review/content/e66184f7-5288-4906-90d5-62c2a8c8b9ab/review
Math's 100% version: https://360.articulate.com/review/content/3fcce81a-7bd1-44a3-b79d-07c2cf38ef4d/review
It looks to me like the slider now has no effect on quality, either for jpegs or pngs. So why bother having the slider to control the quality of images?
Another test - I published the story file set at 80% quality, then at 100% quality. The file sizes of the images are the same regardless of the publishing settings.
I still don't understand the presence of the slider, since it doesn't seem to mean anything regarding the quality of the images.
I received a message from Matthew Bibby:
The slider does work, drop it down to 10% and you'll see. You'll also notice different results depending on the complexity of the image.
The bad quality of png was the wrong png24* import as jpg (!!!) to the media library
Problem is fixed by articulate for new png import, but "old" projects have to be changed manually -> re-import all png24

*png24 = png without alpha channel
Although the name wasnot 100% correct it is a png. Did check it in the medialibrary just now.
Or Jurgen meant... it was an old bug of Articulate and it is fixed now ;-)
yes, I meant the old (fixed) bug
