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.
