Extraction Modes
Manual Manually capture screenshots from timeline.
Interval Extract screenshots by incremental time, frame or fixed count.
Automatic Detect and capture screenshots by changes in content.
Histogram Diff compares the overall distribution of colors and brightness between frames to detect and capture scene changes.
Pixel Diff compares individual pixels between frames and measures how much of the image has changed to detect and capture scene changes.
Transcription uses timestamp segments to capture frames. Requires a corresponding SRT or VTT file.
