I usually have several sources in my timelines, 2 at a minimum but not seldom up to 5-6. A couple of versions back I had an issue with PD skipping sources when producing a video and I just bought PD 15 and it's worse than ever. Had a project of 10 clips and this is my 5th Batch Produce and PD only managed to include all sources in 4.
Hardly ever had this issue with that in PD14. As for now, I have to revert back since I've fallen way behind in my work. Might go back in the future if anyone have a sollution. I just hope my saves from PD15 works in 14 as there is two days of work...
