Custom Transitions

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.

Try disabling parallel processing in Export. Do both clips in the transition extend beyond the transition - both beginning and end?

Thanks Dan, parallel processing is what caused it.

I just fixed this for the next version so you should not need to disable parallel processing.
