Have you selected the checkbox "High Fidelity" while importing the ppt file.
Thanks for answering. Yes, I did check "High Fidelity" when I imported the PowerPoint. Does HTML 5 definitely support image fades?
Was this ever resolved as I am having very similar issue? My animations with fading from PPT work when I preview in web browser, and when I play the slide, but do not work when I preview with HTML5 in web browser.
HTML5 output will work for PPTX files with High Fidelity checked in PowerPoint Import dialog while importing on Windows.
It will not work for PPT file as mentioned in your post. You can save your PPT as PPTX if that is the case.
If you still see the issue. Please mail me the pptx file.
