Hi,
Thank you for your enquiry.
Opus does not handle SWF files directly, but instead uses the QuickTime engine to play SWF files imported as video objects. I would therefore recommend opening the SWF file into QuickTime to see if the problem occurs.
If the problem is also evident in QuickTime, please try downloading and installing the very latest version of the QuickTime Player from
www.quicktime.com, then test to see if this resolves the problem.
If the problem is still present in the latest version of QuickTime, I would recommend contacting the developers of the original SWF demo software to see if this is a known issue.
It may be that they have only tested the outputted files with the Flash Player browser plug-in and not with QuickTime. If this is the case, please try importing the SWF file using the DocView object. This will force Opus to use the Flash Player browser plug-in to handle the file and the demo should play back at the correct speed.
I hope this helps. Please do not hesitate to contact me if you have any further queries.
Kind regards,
