  • 1.  Getting a Material Duration

    Posted 03-19-2025 20:17

    Hi all!,

    I have a XPression scene that is a simple video clip player. I've managed to add a "pause", "no pause" radio checkbox for the producer that works with VB script.

    What I want to have happen now is for the preview marker to automatically be set to the end of the clip. I don't know a simple way to do that, so I've been going the route of getting the duration of the material and in my testing, I'm just sending that value to a text object.

    Now, when I change the video clip on the published material in Sequence, I want to see the value of the duration change and I'm not seeing that. It just stays with the original material. I know I'm reading the duration value as the number changes when I directly modify the video shader.

    I've tried adding the script that gets the duration to the other run levels like OnPrepare, etc. - Any ideas?

    At the very least, I've gotten some scripting practice in tonight.

    Hi Roman,

    Thank you very much. I see the biggest mistake I made. I wasn't referencing the material on the actual quad being changed, I was just getting the material in the project. Fantastic!

    Hi all,

    As I've gotten into this more, I'm running into some walls.

    A little background. I wanted to improve the video player scene we have. What doesn't work now is the producer can not play the preview in the NRCS plugin. I thought that if I could set the preview marker to wherever the clip ended, maybe the play-head would work. I can now get the duration of the clip, but I don't see a way to set the location of the Preview Marker, only the Default Marker.

    Any ideas on what I'm doing wrong?
