- Film is captured at 23.976 fps (not actually 24 fps)
- A USA Blu-Ray is played at 24 fps
- EU broadcast is 25 fps
If you want to pair Latvian audio from a Tet+ stream (Baltic Streaming service) with a USA Blu-Ray,
you need to adjust the video playback to be 25.025025024 fps - which turns out to be 24 * (25 / 23.976).
It's better to squish the USA video than to expand the EU audio because the audio has already lost information that cannot be reexpanded, but the video has extra frames that can be dropped or merged with minimal loss of quality.
