IS MY VIDEO RECORDED IN VARIABLE FRAME RATE?
Most local editors like TimeBolt, Adobe Premiere, and Resolve struggle with Variable Frame Rate (VFR) videos due to inconsistency in the timing of frames. The video and audio will de sync overtime, or not preview at all.
Checking if a video has variable frames is not straightforward so we built vfr-detector to analyze video for you.

Why record in Variable Frame Rate?
The answer is efficiency. VFR allows the camera to adapt to different scenes and motion levels. In fast-moving scenes, a higher frame rate can be used, while in static or slow-moving scenes, a lower frame rate is applied.
This adaptability makes VFR efficient for capturing dynamic content without wasting frames or file size on uneventful scenes. iPhone video and screen capture software like Loom, PowerPoint, and Zoom record in VFR to optimize for file size and bandwidth.
For live streaming and gaming, VFR is used to adjust frame rates based on the available bandwidth and complexity of each scene, and why OBS may record a Twitch stream in variable frame rate.
And while VFR brings flexibility and adaptability to video recording, adjusting to the scene's requirements, and optimizing resources, it makes post-production a lot more complex.
VFR-Detector by TimeBolt can fix it for you.
