Blurry images in Storyline 360 November 2021
Support says it's a bug. But I don't understand why isn't everyone complaining about blurry images here? I can't believe hundreds of users are suffering in silence, so am I the only one?
Hi Mark. I took the liberty of peeking into your file and checking things out. I completely understand your frustration because I can find no reason why it displays blurry upon preview or publishing.
One caveat; I notice a lot of folks do this so it's not pointed at you - PNGs are only necessary to use whenever your bitmap image has a transparent section. If it doesn't then a JPEG is the optimum file format. The reason is that PNGs tend to be far larger in 'size' than JPEGS.
Which brings me to JPEG image compression.
Generally, the more compression applied to a JPEG upon export the more degradation there is in the image (blurriness, pixelisation, artefacts, etc). I have uploaded a version of your file to Review with 4 buttons that show whatever differences there are between the formats and compression.
Weirdly, there is little or no difference in the visual result between your original PNG (2048x1536px which scales down to 720x540px in the SL360 file), a straightforward high quality (zero compression) JPEG and a resized JPEG (720x540px import - actual size).
The only noticeable difference is in the third option which was the original size JPEG compressed to Very Low Quality (10) and the result is predictably bad.
But what is concerning is that this deliberately bad image is not really that far off from the other 3. So yeah, conclusive proof that I have no idea what is happening to your image. there is no reason, AFAICS, for the quality to publish so poorly.
Not sure if this helps at all.
