Usually my pc would encode 20 minute video in 1.5-2.5 hour, and the video would come out exactly as I see on timeline.
Sometime my 20 minute video would take 25-30 hour and the file size would be ~20GB and the text would come out in black color instead of white as I have in timeline.
Tell us more about your project: filters used, edits made to the clips etc. The more information you give (incl. Screenshots) the more precise the answer can be. For example: if you use lots of filters (and some filters are very demanding and time consuming like stabilizing filters or levels/gradients, sharpening) - as every single image has to be processed - it can take a lot of time. But what you report is really very unusual - 50 min. encoding for 20 sec. video? That sounds really odd - there must be something wrong in your settings i guess. Show us your video mode, project settings, filters e.g.
I redone the file not to use scrolling text and instead make gif now 15 minute video take 9 hour instead of 18 hour.
total 3 videos track and 1 audio track
track 1 no filter - 1 hour video 1 trim to 15 minute
track 2 size filter -18 minute video trim to 15 minute
track 3 size filter - 42 gif file ~1mb per picture
I include the screenshots

What exactly is your Shotcut version? (Help → About Shotcut)
This is the version I think you have installed. Better to know for sure.
Example:
What are the specifications of your computer?
Operating System (Windows, Mac, Linux)
CPU
Memory
Data drives (M2.NVME, SSD, HDD) What is Shotcut installed on, and what type of drive is all of your media on for this project?
Anti-virus programs installed? Have you tried to whitelist Shotcut, or turn off all Anti-Virus programs?
While exporting, how hot is your CPU getting?
Now let’s look at your source video files.
I know these are proxy files created through Shotcut.
If you were to open Shotcut for a new project, open each original video file.
What does Shotcut show in the Properties area?
Example:
In your main project file, what is the Video Mode Resolution & Frame Rate? Click on Output, then Properties.
When you exported, did you change anything in Export → Advanced? If so, what did you change?
