Where MKV files go wrong
| Slip | Result | Remedy |
|---|---|---|
| Sending an MKV with game sound louder than the voice | The voice is covered and the summary is thin | Lower the game volume in OBS before recording the MKV |
| Sending an MKV whose voice sits on a second audio track | The summary may follow the wrong track | Send the MKV with the speech on the main track |
| Taking the summary as a full stream log | Chat reactions and quick jokes get left out | Read the transcript for details |
| Sending a huge MKV when only a short part matters | The digest spreads over filler instead of the key part | Cut out the relevant stretch first, then send it |
