+
+        Fragmented MP4 and (especially) MKV files may not be read properly / recognized by video editors, which requires you to manually remux each one, though if your recordings are important and you can't have them get corrupted upon OBS / your OS crashing, you should use them.
+
+        Fragmented MP4 is notorious to mess up in VEGAS, though remuxing to regular MP4 fixes it. 
 
-    I highly recommend switching from the default to the Fragmented MP4, as it brings the advantages of recording in MKV whilst not having to remux MKV to MP4 for compatibility.

                 1. OBS describes low Presets as "Lower Quality" in the context of <u>streaming with CBR in bandwidth-limited scenarios</u>, if used for recording it'll be much more performant to record at the cost of bigger file sizes.
