I’m using the custom transition (Jonrays 161 transitions) but I seem to be having difficulty. When I create the transition within Shotcut and play it back the transition looks fine but upon export I’m getting varied results.
On some exports the transition works okay but shows a frame of the second video is seen just before the transition starts. Again in Shotcut itself a review prior to export is fine.
Here is an example export of one of JR’s paint transitions. Again this looks fine in Shotcut, the issue arises on export.
