Here is an intro I created using Shotcut and Glaxnimate. This is for all those people looking for a little inspiration. And remember, you are only limited by your imagination since this software can do more than enough . This was an incremental process for me, and it took about 4 or 5 cuts; it seems like that’s just how I work.
As an FYI the entire thing can be done in Shotcut, as demonstrated by this link, and please remember I am barely an intermediate user, and imo anyone who spends a little time learning the program can expect excellent results.
Also, the film projector footage is 4k (cut down to 1080p) and completely attribution free for commercial and personal use, so this is all above board!
Edit: You can download the entire project as a zip in post #4 below.
