Analyzing Video Frame Rate (FPS)
This frame rate analyzer measures your video's actual frames per second, including average FPS, minimum FPS, maximum FPS, and total frame count. All processing happens in your browser—no upload required.
The tool reads each frame's timestamp and calculates the instantaneous frame rate. This reveals whether your video maintains a consistent frame rate or varies throughout.
Who Needs Frame Rate Analysis
- Video editors who receive footage with playback issues. They analyze frame rate to diagnose whether variable frame rate is causing problems.
- Gameplay recorders who want to verify their capture software is maintaining the target frame rate. Analysis confirms consistent performance.
- Content creators troubleshooting stuttering playback who check if frame rate drops are the culprit.
- Developers testing video playback performance who measure frame rate consistency across different videos.
- Specification verifiers who confirm the actual frame rate matches the claimed rate.
What to Know Before Using It
- Average FPS is the overall frame rate. A "30 fps" video should average close to 30, but might vary.
- Min and max FPS show the range of variation. Large gaps indicate variable frame rate, which can cause playback issues.
- Total frames divided by duration equals average FPS. This is a useful sanity check for the analysis.
- Some videos use variable frame rate (VFR) intentionally. Screen recordings and gameplay captures often vary based on content complexity.
- This is a measurement tool, not a fix. To convert VFR to constant frame rate, use video editing software.
FAQ
- What's a good frame rate?
- Depends on the content: 24 fps for cinematic video, 30 fps for TV/web content, 60 fps for smooth motion (sports, gameplay).
- What causes variable frame rate?
- Recording software adjusting to content complexity, screen captures matching display refresh, or encoding optimizations.
- Is variable frame rate bad?
- Not inherently, but VFR can cause issues with some editing software and players that expect constant frame rate.
- What does min/max FPS tell me?
- Minimum FPS shows the worst frame rate drops. Maximum shows peaks. Large variations indicate inconsistent frame timing.
- Can this detect dropped frames?
- Indirectly—lower-than-expected FPS suggests dropped frames during recording or playback.
- How accurate is the analysis?
- Very accurate—it reads actual frame timestamps. The analysis reflects what's encoded in the file, not playback performance.
