In Simple Terms
The standard for anything involving video — film, TV, YouTube. If your music is going with a picture, export at 48 kHz or you'll create sync problems.
In Practice
All audio delivered for a Netflix documentary is exported at 48 kHz, as required by broadcast specifications.
Common Confusion
Using 44.1 kHz for video projects is a common mistake that can cause subtle sync drift or require unnecessary sample rate conversion.
