#126 When switching channels, input settings are not applied to the sources until starting transition is complete
What steps will reproduce the problem?
- Create a WCS studio with two channels.
- Set transition (for example) to fade in/fade out for both channels
- Set an input to appear in both channels, but with different size and position.
- Switch between the two channels
What is the expected output?
The first channel should fade out and be replaced by the second channel as it fades in. It should be some kind of a smooth transition.
What do you see instead?
First channel fades out. Second channel fades in, but any inputs it shares with the first channel look as they did in the first channel. Then when the fade-in is finished, those inputs suddenly change to how they should look in the second channel.
The Operating system you are using (Linux, Windows etc)?
Linux (Debian stable/testing)

In a more general sense I think the current implementation of transitions is kind of problematic. For instance, what I'm going for here is a two-camera setup - using the camcorder to fill most of the frame and the webcam as a facecam occupying a smaller area of the display. Then for portions where I don't need the camcorder, I'd switch to the other channel and have the webcam fill the full frame. But there's no way to make that transition smoothly, at least as far as I can tell.
Ideally I think I'd want one of two things for this transition: Either the two channels should cross-fade, or the camcorder should fade-in/fade-out and the webcam should translate and resize to make the transition. To be able to provide both would probably mean supporting channel transitions and source transitions as separate concepts in the UI. (apart from the fact that cross-fades aren't supported, fade-in/fade-out apply to sources, not channels - so when you "fade out" a channel that has overlapping layers, the individual layers "fade out" to transparency - meaning that while the fade is happening, you can see the overlap.)
Yes George,
the transitions is really problematic ... I tried to make them usable but with no luck as you can see ...
The only way to have a smooth transition is to apply the selected transitions to all stream and all channels, and if you use webcams, not to stop the webcams from one channel to the other, but switching the layer down to hide the camera.
Thanks for the feedback.
