In Dorico 3, I attached a video. When playing, the video consistently goes black and silent on the 3rd beat of measure 22, or 1 minute and 22 seconds. I’ve confirmed that the actual attached video continues in a video player. I’ve confirmed normal settings in video properties, the only adjustments being a video offset of 00:00:00:09, and Project frame rate at 30fps, which is also the video frame rate. In Play mode, I’ve confirmed the video region is not truncated. There are no markers. I also saved the project and restarted Dorico Pro 3 to no different effect.
Why would the video just stop?
