I've researched about Frames, Start Frame, Offset and based on my research Frames is the total amount of frames in the video or any frames lesser than video, Start Frame is the frame in the main timeline where the video texture should start playing and i've set it to 700. That means when i render frame 615, the picture displayed in the face with the video texture should be at frame 1 but apparently that isn't the case for me. So my question is, is it a known bug or did i misunderstand these fields? By the way, my first instance of the video texture worked but the second instance is not working.
UPDATE:
i finally got it working after clicking this icon in red box:




offsetor thestart frame, nothing works. so that obviously is a bug? – Harry McKenzie May 26 '22 at 12:20
