I noticed you can use some variables for setting your file path when outputting to file. Here you can see im using the {date} variable which simply names your file according to the date (ex. 2014-01-10-1823-11.mp4)
Only I can find no documentation of this and can't seem to find any others. I use OBS as my desktop recorder since its 1000 times better than Fraps, and it would be so amazing if i had a whole list of all the variables supported. Things like window title or the user that made the recording would be absolutely amazing. I hope someone has the answer to this
EDIT: It seems like it also puts the date if you just leave the filename blank so it may not be a variable thing at all, I dont know
