Before I start, I still have an issue with getting videos to appear on Screen 2, instead of Screen 1, but that's a different issue that's already been reported.
Video fading works on 5 beta 3, but does not fade the audio along with the video. On 4.13.1 I found a way around that by separating the audio and video into 2 different files and putting them into a collection. I've done the same in 5 beta 3 but the audio is always ahead of the video (or the video is lagging). I haven't found a way to synchronize them in 5 beta 3. In 4.13.1 playing the same collection a second time will put them in sync.
I will have to test with more videos to determine if the difference is consistent.

I tested with a few other files and the offset appears to be consistent. When using separate audio and video files, the audio is roughly 900ms ahead of the video. I can sync up the audio & video by adding 900ms to the audio file, and they appear to synchronize all the time.
I did find another problem. Since I can't get my videos to play on Screen 2, I moved QLC+ 5 to screen 2 so I could view the video full screen. When I click the button assigned to the fade collection, the video has 2 perceptible blackouts, just a few milliseconds long, when the fade out starts. This doesn't appear to happen when the video is set to Windowed.
I tried capturing the issue with the XBox capture function, but it won't allow me to capture the video while in full screen, and the problem doesn't occur in windowed mode.

I have implemented audio volume adjust. Please test with latest GitHub Actions build.
Have I already told you that display output is correct on Linux?
Also, please test this
https://www.qlcplus.org/downloads/test/ ... ?p=Windows
It's the first Qt 6.x build for Windows. Media playback has definitely improved (they finally decided to use ffmpeg, same al VLC)
I haven't checked yet but maybe the display output issue is fixed too.

I just tried that version. I'm not able to get the video to fade at all. I tried the standard method of fading audio, and I tried the using the collection that worked to an extent in the current released version 4.13.1. I also tried using the video in a chase and adding a fade out there. None of these worked. I'm not sure if I should be using some other method.

I tested it with a playback slider in the virtual console. So basically you can attach it to a regular Scene fade in conjunction with loopback.
At the moment, the video function doesn't support native fade in/out settings.
I might add it to complete the feature set

I tested it again and I must be doing something wrong. I can play the video, but I can't get it to fade. I tried a few different videos (WMV is my default format). Some listed the video and audio codecs as Invalid, though they did play. In this example I used an MP4 which showed H264 and AAC for the codecs.
I've attached my project and a screen shot of the video properties. My video is too big to upload.
Thanks for your work on this Massimo.

Hi Ken, I just downloaded the latest v4 build for Windows and installed it.
Then I downloaded this sample wmv clip
https://file-examples.com/index.php/sam ... -download/
In QLC+ created a Video function.
In Virtual Console created a slider and attached the Video function to it.
Go to operate mode, move the slider and I can correctly see the fading.

The version you asked me to try, QLC+_4.13.2-Qt6-GIT-20241207, doesn't fade at all. The current released version, QLC+_4.13.1, will only partially fade the video. I've attached a picture of a video with the fader down to 1. It also doesn't fade audio. We discussed it in this thread, https://www.qlcplus.org/forum/viewtopic ... ade#p75147

Sorry for the confusion, they're two different versions to test for two different issues
The ones from GitHub actions are for audio/video fading:
https://github.com/mcallegari/qlcplus/actions
The build based on Qt6 is to test if display on secondary monitor is fixed too. Also, since the backend is based on ffmpeg, the A/V startup lag is much less compared to Qt5. So A/V cues should be much smoother

I haven't been able to get QLC+_4.13.2-Qt6-GIT-20241207 to fade videos. Fading still works for audio.
I downloaded QLC+-compile-qt5-4.13.2-20241212-2d87473. The video fades, but not completely, the audio does fade.
For version 5, I downloaded QLC+-compile-qt5qml-5.0.0-20241212-2d87473. For the video/audio fade, this seems to work perfectly, but I still have my video assignment problem. Set to Full Screen only plays on Screen 1, even if Screen 2 is selected. Windowed plays on Screen 1 when selected, but doesn't seem to play video when Screen 2 is selected, thought the audio does play.
