I don't know how to code, but as an Android artist who enjoys using Krita, I came across a problem. Krita can *save* timelapse frames on my tablet, but it can't render the video on its own because of some Android quirk about not having ffmpeg, I don't quite understand it to be honest. 

So I had to take matters into my own hands and created these flows to 1- find the directory Krita is saving frames in and 2- Render the timelapse.

First, the flow checks if Krita is the foreground app. If yes, forks into the other fibers. When Krita is minimized or closed, stops the other fibers and  removes "Openfile" (if it exists) from media. This is to prevent thousands of frames from clogging my gallery app.
 
If Krita is running, the flow will start searching for the directory in which Krita is saving frames.

I realized that Krita will always create new directories when it starts a new recording, and the folder name will always be 14 characters.

So, I made the fiber list every 14-character folder in /Krita and used a looping For Each block to monitor files in every index of the array. (When it executes the For Each block it erases the 0th value of the array and executes the For Each block again, until the array is empty.) 

This creates a new fiber for every recording folder I have, monitoring these folders for new files (frames) Krita is creating. When one of the fibers find something, it sets the directory as the "OpenFile" variable, and stops the other searching fibers. 

(If I create a new recording, that directory will be added to the array and the For Each block will be restarted, otherwise the flow simply won't see it.)

When "Openfile" is set, it shows a notification asking if I want to render. If I pick "yes", it will start the second flow (the one that actually renders using Termux.) 

That flow is simpler, it just backs up and deletes /Krita/Recorder/Render if it already exists (just in case something went wrong somehow and it wasn't deleted) copies whatever folder "OpenFile" is at that moment to /Krita/Recorder and renames the folder as "Render", runs Termux to render every file in /Krita/Recorder/Render as "Render.mp4", allows you to preview the rendered video if you want, backs up and deletes.

Anyway, I just wanted to share these flows I made to solve a problem I imagine very few people have.

I'm so proud of myself.
