class  pixeltable.iterators.VideoSplitter

Iterator over segments of a video file, which is split into fixed-size segments of length segment_duration seconds. Parameters:
  • duration (float | None): Video segment duration in seconds
  • overlap (float | None): Overlap between consecutive segments in seconds. Only available for mode='fast'.
  • min_segment_duration (float | None): Drop the last segment if it is smaller than min_segment_duration.
  • mode (typing.Literal['fast', 'accurate'], default: 'accurate'): Segmentation mode:
    • 'fast': Quick segmentation using stream copy (splits only at keyframes, approximate durations)
    • 'accurate': Precise segmentation with re-encoding (exact durations, slower)
  • video_encoder (str | None): Video encoder to use. If not specified, uses the default encoder for the current platform. Only available for mode='accurate'.
  • video_encoder_args (dict[str, typing.Any] | None): Additional arguments to pass to the video encoder. Only available for mode='accurate'.
