Poor image quality in SL2 and poor video quality in SL3
Oct 25, 2017
We are developing simulation-based courses for our client and are using a lot of images in videos. The authoring tool is Storyline 2.
When we shared the published output with our client, the client raised issues regarding the poor image quality. The images are not looking crisp and sharp. The client tested the HTML5 version of the courses on IE, Firefox, and Chrome. On Chrome, the quality of the images are worst and not at all acceptable per client.
We then advised the client to run these courses by enabling the Flash player. But since there will not be any support for Flash going forward, the client would like to run only the HTML5 version.
To resolve this poor image quality problem, we published the output from SL3. But here the problem is with the poor quality of videos. As per client, the video quality is better in SL2 than SL3.
Now we are in a catch 22 situation. If we publish the course from SL2, the image quality is suffering. And if we publish the course from SL3, the video quality is suffering.
Here is some testing analysis for images and videos. Flash was disabled for all testing:
HTML5 output from Storyline 3: IE11 (Flash disabled), Best quality, Text and images are crisp, screenshots are the neatest, very poor (unacceptable ) video quality
HTML5 output from Storyline 3: Chrome (Flash disabled), Lower quality than IE11 with SL3, Text and images are readable but more fuzzy, screenshots are more fuzzy very, poor (unacceptable ) video quality
HTML5 output from Storyline 3: Firefox (Flash disabled) Quality comparable to IE11, very poor (unacceptable ) video quality
HTML5 output from Storyline 2: IE11 (Flash disabled), Unacceptable image quality - Lower quality than Chrome with SL3
HTML5 output from Storyline 2: Chrome (Flash disabled), Unacceptable image quality - About the same as IE11 with SL2
HTML5 output from Storyline 2: Firefox (Flash disabled) Unacceptable image quality - About the same as IE11 with SL2
Note: We have used Tiny PNG to compress the source images, but while publishing the output from SL, we have used the maximum quality.
Can you tell me how we can resolve this problem?
