+## Output lag and compensation
+
+The S5II\* suffers very bad output lag.
+
+Lag improves HDMI audio is disabled.
+But at it's worst, video trails audio by 5-7 frames (on an average audio interface).
+
+And it get's wierd…
+Using the same hardware (with different software) requires slightly different offsets.
+
+These offsets work for me, with both camera and microphone going thru RodeX Streamer X.
+
+| Software   | Feature name | Offset                   |
+| ---------- | ------------ | ------------------------ |
+| Ecamm Live | Mic Delay    | +5 frames (167ms @30fps) |
+| OBS        | Sync offset  | +7 frames (233ms @30fps) |
+
