What do OBS Studio's libobs docs say about output frame-rate representation and audio/video sync offset, and is a variable-frame-rate recording mode documented?
OBS (libobs at 32.2.2) runs its output at a fixed frame rate expressed as an integer fraction (fps_num/fps_den), set in the UI as a common, integer or fractional value. The UI strings searched have no variable-frame-rate option, so recordings come out constant frame rate, which is convenient for editing.

Curator qualifications: Docs and code read 2026-10-22; OBS not run. Source audio sync-offset description (reference-sources.rst) carried from producer reading; absence of VFR is scoped to the files searched.
Limitations: Docs and code read 2026-10-22; OBS not run.
Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
