## Delete When
- Delete this scratchpad once the optimization backlog is either converted into issues/work items or distilled into durable project guidance.
## Missing Timestamps
Detect ffmpeg warning "Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly" and try autofix by -fflags +genpts -> Warning if fails -> Error. Check if flags collide with anything.
