I had terrific support from people of this site and from downloading some great tutorial videos for my first handling of this program.
I thought I was doing great when all of a sudden the section of scrolling text I added began appearing in the same segment that originally only had the title. Now I have text scrolling fast over the title, then reappearing where I set it and scrolling at the speed I established.
Did I accidentally do something wrong, or is this a Shotcut bug?
Filters are attached to whatever is selected. In case you had selected a track or Master and added a filter, then a funnel icon appears in the left hand column of the timeline to indicate a filter is active. Then, each clip on the timeline can have its own filters. So, you need to select clips and look at their filters, or look at track filters to see where a filter is added where you do not want.
