+- Merge audio tracks with equal weights
+  - `ddmpeg -i in.mp4 -o out.mp4 -m 1`
+- Merge audio tracks, with the second track being louder than the first
+  - `ddmpeg -i in.mp4 -o out.mp4 -m 1,5`
+- Suitable for sharing clips but you don't want to break people's headphones with your screaming
+  - `ddmpeg -i in.mp4 -o out.mp4 -d` (dampens loud noises)
+
+#### set target size
+
+- Try to shoot for a 30MB video
+  - `ddmpeg -i in.mp4 -o out.mp4 -s 30m`
+
+#### putting it all together
+
+- Share your Valorant clip!
+  - Your clipping software captures 5 minutes, but you only want the last 30 seconds.
+  - The first audio stream has your desktop sounds, and the second audio stream has your microphone sounds.
+  - Your microphone was pretty loud, so you want to make sure that has less weight when we mix the streams.
+  - You're going to share this on Discord, so you can't let it go over 100MB
+    - `ddmpeg -i in.mp4 -o out.mp4 -t 4m30s: -m 3,1 -s 75m`
