Read Video Node

The Read Video node is designed for playing video files. It supports a wide range of file formats and codecs.


  • Path: This property allows you to specify the path of the video clip they want to open. After selecting a file, the "Load File" function must be called to load the chosen video file.

  • Resolution:

    • Default: Scales the clip frames to the default texture created by media.

    • Native: Resizes the output texture to match the resolution of the video clip.

  • Loop: When enabled, the video clip will start playing from the beginning after it ends. If disabled, it will show the last frame at the end of playback.

  • Speed: Allows you to adjust the playback speed of the video clip within the range of 0.25x to 2.0x.


Load File: This function loads the selected video file. It should be called after specifying the file path. If a clip is already playing, the newly loaded one will automatically begin playing after loading.

Play: Initiates playback of the video clip. Pause: Pauses playback of the video clip.

Rewind: Rewinds the video clip to the beginning. If the clip is playing (even if showing the last frame), it will play from the beginning. If the clip is paused, it will display the first frame.

Seek Time: Allows you to seek to a specific time in seconds within the video clip.

Seek Frame: Enables you to seek to a specific frame within the video clip.

Seek TimeCode: This function seeks to a specific timecode within the video clip, with supported formats including seconds, seconds and frames (drop and non-drop timecode), and full format timecodes.


Drop-timecode is only supported in clips with framerates of 29.97 and 59.94. If you seek with drop format in any other clip, non-drop timecode is used, and the value in the function is updated.

If you seek to an invalid timecode in drop format, such as "00:02:00:01," it will be replaced with the first following legal timecode.
