Get Sequence Property

Category: Pr Sequences Get Sequence Property block screenshot

Reads one property from a sequence, using the active sequence by default when `sequence` is omitted. The `HAS_OBJECT_MASK` property reports whether Premiere currently sees any object mask usage on that sequence.

Inputs​

InputRequiredValue KindTypesEnum Values
sequencenoexpressionreference, string, null—
propertyyesstringenum-stringNAME, GUID, TIMEBASE, VIDEO_DISPLAY_FORMAT, AUDIO_DISPLAY_FORMAT, VIDEO_FRAME_RATE, AUDIO_SAMPLE_RATE, AUDIO_TRACK_COUNT, VIDEO_TRACK_COUNT, CAPTION_TRACK_COUNT, IN_POINT, OUT_POINT, END_TIME, ZERO_POINT, PLAYER_POSITION, HAS_OBJECT_MASK, IS_DONE_ANALYZING_FOR_VIDEO_EFFECTS

Notes​

  • Reads properties directly from sequence context (sequence optional; active sequence by default).
  • Includes timing-audit metadata such as VIDEO_DISPLAY_FORMAT, AUDIO_DISPLAY_FORMAT, VIDEO_FRAME_RATE, and AUDIO_SAMPLE_RATE.
  • HAS_OBJECT_MASK reports whether Premiere currently sees any object mask usage on that sequence.
  • Display-format values are returned as stable DSL strings when known, otherwise as UNKNOWN_*_TYPE_<number> so host drift stays visible.

Examples​

Create Sequence From Local `.sqpreset` Path

Creates a sequence from a fixed local `.sqpreset` path. This stays visible as the canonical local-path counterpart to the portable embedded-preset example, and its runtime check confirms that the unusual 2000x1000 frame size really came from the preset.

Render Active-Sequence Frames At Equal Distances To Fixed Folder

Exports a small evenly spaced set of `.png` frames across the active sequence to a fixed folder path, so visual timeline sampling can be runtime-validated deterministically.
