Problem
Mixed camera frame rates cause uneven motion and timing inconsistencies when sources are composited.
Solution
Root Cause / Diagnostic:
Operating cameras at mismatched frame rates (e.g., one camera at 24fps or 30fps and another at 60fps) within a unified 60fps broadcast canvas forces the compositor to perform frame duplication or frame dropping. When switching between camera angles or displaying picture-in-picture composites, the motion cadence shifts noticeably from cinematic/jittery to hyper-smooth. This visual inconsistency disrupts viewer immersion and can cause audio-video sync drift.
Actionable Fix:
1. Standardize internal output frame rate across all production cameras to an identical setting (e.g., set every camera strictly to 60fps or 30fps).
2. Set the base canvas and output FPS in OBS Settings > Video to match the chosen unified camera frame rate.
3. Cycle through multi-camera views and inspect motion smoothness on moving subjects to verify uniform frame pacing across all angles.
Pro Tip:
Matching frame rates also standardizes shutter speed rules across your studio (e.g., 1/120s shutter for 60fps across all angles), ensuring uniform motion blur and visual cohesion.
