Appendix: JSON Scripting Directly > Using Markers and Play Features

Timeline Markers

When Delta creates the show file from the JSON file, it adds markers at the start and end of each clip in the format "Clip_Start_<ID>" and "Clip_End_<ID>" where ID is the ID specified in the JSON file.

You can then navigate to these markers using the external control: GOTOMARKER "markername".

InPoint, OutPoint, and LengthMode

Changing LengthMode to "in/out" uses "InPoint" and "OutPoint" external controls to trim the clip. If using this method, the Length property of the clip should be changed to reflect the new length of the clip.

If Length is then longer than the trimmed clip, the clip will be looped to fill the number of frames specified in Length.

PlayMode and PlayModeDetails

If "PlayMode" is changed to "PlayCount", then the clip will loop the number of times specified in "PlayModeDetails" before moving to the next clip.

FadeMode and FadeModeLength

Changing "FadeMode" from "None" to "Transparent" adds a fade in and out effect to the media over the time set in "FadeModeLength".

If the previous clip has no fade, the video level drops to 0 then fades in. If the following clip has no fade, a 5-frame fade-in is applied.
