I made an account just to give props to this idea. It seems like a simple solution but I appreciate it a lot, since I was individually writing out each timestamp in a text file before this, and I was wondering if there was an easier way. Thank you!
I'd also like to mention to new downloaders to make sure the files are going in the right place. For me, it was C:\Program Files\obs-studio\obs-plugins, so make sure you're not having to create an obs-plugins folder when you install. Also, you'll see the infowriter source in the list of new sources, below Window Capture. I hope this helps because the installation instructions were a little vague for a first-timer like me.
The Formating of the .txt file could use some work. Such as an rubric on the format like in OBSs's recording popup that tells you how to format the video. Beside that the plug does exactly what it needs to do.
I press NUM0 (personal map) and it puts a time stam in the txt file.
Extreamly usefull if you need to make highlights and don't want to search threw 3 hrs of record for that one spot you don't want to loose.
