What effects are you using on your clips? There may be some effects that LumaFusion can’t translate as part of the XML, so the first thing I would do is strip any effects from the clips in your sequence, and see if you can then export ANY flavor of XML (trimmed media, full media, or data only).
And why is the frame rate different between your source media and your project settings? This potentially could also be causing a translation error when LumaFusion is compiling the XML data.
When I did my test yesterday, my clips had no effects at all, and my project frame rate and source media frame rates matched. So perhaps let’s get back to that point and see if that helps.
Sorry only just saw this. There were no effects and frame rates were the same. Seems to have sorted itself by exporting with trimmed media.
Thanks for your help.
