Do the settings under Preferences Project SWF SIze and Quality have any impact on HTML5 output?

Question

I can see how Audio quality and Jpeg quality could be affected by making changes here, but I'm not sure if it actually makes any changes in the HTML5 version. Can anyone shed some light?

Answer 1

Hi Noel,
Me again, sorry for that.
The default quality for slides is Low (8-bit), to have the smallest filesize for output possible. But in a lot of situations this quality is too low, after all this means that you only have 256 colors (like in GIF-images) which is too low for most photographic images and certainly also for images with (partial) transparency. And as you perhaps already saw in the forums, some fonts do gain a lot if you increase slide quality.
To increase slide quality you have two options:
either you check each slide and change the quality to High or Optimized if necessary, and only then;
or you just override the slide quality at publishing and in that case you uncheck the mentioned option 'Retain slide quality', and set all slides to High
The second option is the easiest one but means that all slides will have High = 24-bit = 16777216 colors available. This will result in a larger filesize than option 1 where you only increase the quality for the slides that need it. If you choose option 1 you do not uncheck 'Retain slide quality'.
Never used it, but for a quick publish with lowest quality you could also use option 2 if you have changed some slides to higher quality, to have all slides again at the low quality.
