Hi Elusien,
Referring to your comments to use " @jonray: 161 new transitions - using “Mask:From File”"
I am into my 8th week of using Shotcut since I first started with Movie Maker end Feb, then found Openshot … in early March and a week later Shotcut. I did contemplated on using Lightworks after reading a review but decided on Shotcut when I found the thread below that gives me the notion that there are really dedicated ppl focus on Shotcut.
So with that said, I had since try to apply what I learnt from this forum and ppl like Jonray, Paul2, samth, Sauron to name a few and yourself, I had manage to make 2 prior videos as a start. Thanks to all these folks to keep me challenged and learning …
Just to show some of the “mask transition” techniques I’d learnt from Jonray (& flashwords) and GL transition, and the other cool Shotcut filters with keyframe. Now that I have learn Credits/text flow … will apply to all my future videos (those for public sharing).
I also will try out “simple masking” and new transition (really cool in your demo video) that I saw last week. The latter seems not working so well I think … need to try outs.
Sharing what I learnt from shotcut on 2 videos I made recently … amateur quality 
1st video : 28 Mar (3 weeks after started with shotcut)
about Living in Corona Crisis … my video technique learnt was extremely limited then.
2nd video : 14 Apr (2 weeks later with shotcut)
Vow Renewal … just a sing along with group of friends planning for a trip to a Resort Island next year
(1 to do list during this “social distancing” / lockdown period)
