 description: "An open source encoder that produces H.264 videos. \n\n- Ensures `remux`\
   \ is not present anywhere\n- Matches both `x264` and `h264` (assuming misclassification\
   \ if `remux` is absent)\n- Matches `DVDRip`, **only if it is NOT followed by** `XviD`,\
-  \ `x265`, or `AV1`\n- False positives may occur with multiple sources (e.g., `DVDRip`\
-  \ and `BDRip` with varying encodes)."
+  \ `x265`, or `AV1`\n- Matches in cases of multiple sources (e.g., `DVDRip` and `BDRip`\
+  \ with varying encodes)."
