Video not fading out or looping (TVG, Win 8.1, 11.4.2.1)

I'm testing running video cues on a second monitor (extension of my desktop) on a newly installed Windows 8.1 Pro machine running SCS 11.4.2.1.

I'm attempting to use the TVG video library so that I can cross fade between cues.

Two problems I've come across:
1. I can't get a video cue to loop continuously in the background. As soon as I play the next cue (another video), it stops the currently looping cue.
2. My videos fade in as desired, but they don't fade out. The audio fades out, but the video just plays until the fade out is supposed to be complete and then stops abruptly.

I've tried each of the video renderers, but have the same problem no matter what.

On my Windows 10 machine running SCS 11.4.0, I get very different (though not necessarily better) results...

Any help you can provide would be appreciated.
(Diagnostic file on its way via e-mail.)
Thanks,
Aaron

Aaron, I can see what the problem is and it's not really a bug - you're trying to do something different to the way video cue processing was designed. What's different is that you are wanting to play multiple videos simultaneously to different parts of a single screen. For example, Q1 plays a video in the top left of the screen, and then Q2 plays a video in the top right of the same screen. SCS currently assumes that only one video at a time is visible on a screen, apart from the period of a cross-fade. Consequently, when you start Q2 and the cross-fade in time is complete, SCS automatically stops and completes Q1, assuming Q1's video is no longer visible. The image of Q1 doesn't fade out because during a normal cross-fade the background image (Q1 in this case) does not need to be faded out as the foreground image (Q2) is being faded in, and SCS assumes (without checking!) that the faded in image occupies the position and size of the image being faded out.

To support what you are wanting to achieve it would be necessary to add a property, either in video/image cues or globally in production properties, to prevent SCS auto-closing any currently-playing cue for the relevant screen. Internally there's more to it than that - I mention that to point out that this would not be a quick mod. :wink:

Fantastic explanation - makes perfect sense - thank you!

In reality, for the show I'm working on now, I in fact won't need to use the different parts of the screen as I had done in my demo; the cues will in fact just take over the whole screen, so I should be all set.

But this is an interesting concept for the future -- although at this point, you start venturing into the realm of features of very complex media servers... :)

Thanks again for the quick and thorough explanation.
I love SCS.
