Video FPS Checker

It analyzes a provided video input (URL or file) to determine the frames per second (FPS). It supports common frame rates such as 24, 25, 30, and 60, and it detects whether the source uses constant (CFR) or variable (VFR) frame timing. The analysis remains lightweight to preserve workflow speed while remaining accurate for typical delivery specs.
Conceptually, the tool first reads container metadata, then estimates timestamps by sampling a frame sequence when metadata is insufficient. The result includes a primary FPS value, an average FPS for VFR sources, and a CFR/VFR flag. It also reports a confidence level and basic diagnostics for problematic sources.
Who benefits: video editors, QA engineers, streaming publishers, post‑production houses, and media teams needing quick preflight checks. Unique value includes fast turnaround, explicit CFR/VFR reporting, and outputs suitable for automation in pipelines. It is robust against missing metadata and gracefully handles common file issues without requiring extra steps.
Core features and use cases: flexible inputs, metadata-first reasoning, optional per‑segment FPS estimates, and exportable results for reports. Use cases include preflight validation before encoding, compatibility checks with platform requirements, and quality assurance verifications for sponsorship and ad-insertion workflows.
