Recorded a video but it has 2 issues: 1. sound is ahead of video for 0.2s and volume is too low. Letting ffmpeg do its magic on the file via:
```
ffmpeg -i input.mp4 -itsoffset -0.5 -i input.mp4 -map 0:v -map 1:a -c copy input.mp4
ffmpeg -y -v quiet -i input_fixed.mp4 -lavfi volume=+10dB -acodec libmp3lame -ab 320k -id3v2_version 3 input.normalized.mp4
```
