Runtime
Runtime refers to the total length of your video content, combining the durations of all individual segments such as Reels, Acts or Clips. For projects configured in Long Play mode, the runtime will be the same as the total duration of the video. Essentially, runtime represents the overall length from start to finish.
The calculation of runtime takes into account the durations of all current versions of pictures within your project.
You may see runtime in the Stats panel and on exported cue logs and cue sheets.
