v1.10.0

NEW
Framerate Detection

• Automatically estimate input video's framerate when a file is loaded
• Display estimated framerate in upload metadata
• Support a set of fractional framerates
  • 11.988, 12.5, 14.985, 23.976, 29.97, 59.94, 119.88
    • Values taken from Adobe Media Encoder's H.264 Frame Rate options to likely cover standardized fractional framerates
• Framerate override still available for manual correction
  • Supports fractions in comma and period
• Use 30 FPS fallback if estimation fails

Updated
Metadata Upload Box

• Move Aspect Ratio into brackets after Resolution
  • Example: 1920×1080 (16:9)
• Replace Aspect Ratio row with Framerate (est.)

Frame and Timecode Accuracy

• Apply decimal framerates consistently to frame controls, filenames and interval captures
• Improve non-drop-frame SMPTE/EBU timecode calculation
• Prevent floating-point drift when capturing at frame intervals
• Improve seeking accuracy between adjacent frames
• Update end-of-video limits based on frame duration instead of a fixed time offset

Other

• Ignore outdated detection results after changing files or manually overriding framerate
• Improve temporary video cleanup after detection
• Remove duplicate Manual frame-control listeners
• Synchronize framerate override with filename frame numbering

Known limitation

• Chromium-based browsers may estimate videos above 150 FPS incorrectly due to browser/display frame callback limits(?) Use Framerate override when needed.

FPS detection originally contributed by TRYOKETHEPEN and expanded through testing and follow-up improvements. 谢谢你！
