How about a link in the chatroom, leading to any external video site that has your cutscenes loaded? Any URL pasted into the chat will instantly render as a clickable link, that opens in a new browser tab or window. If your group uses Google Hangouts there is even a way to start a Hangout where everyone can start the same YouTube at the same time and watch together. Here's how I would do it though. With the new Roll20 sound features, you can attach an audio track to a certain Page, so this would be like a still-life cutscene (non video but a series of pictures) or like a comic strip (populate the Page with multiple still images in a sequence). The reason this would feel sort-of like a cutscene is: The GM will drag the Players ribbon to this new page, and everyone will Reload to the new page (showing a temporary black screen as Loading --- this is the feeling of the cut), and then the new music track for that page will automatically start playing, and the still-images will start to populate --- this is the scene. As an enhancement the GM could press "Shift Z" on each image, in sequence (Shift Z is a technique to make a picture pop-up in full screen lightbox mode with a shaded background!), as the background track plays throughout. The song would be continuous, and the pictures would come boom, boom, boom. The song itself can be one you found on Soundcloud or Tabletop Audio, or it could be your own custom audio from the voice of the Narrator which you have pre-loaded onto Soundcloud. Then GM moves the player ribbon back to the playing-surface tabletop, causing again the black loading cut as the party fades back to game play screen. Example format: Players kill big boss enemy in game. GM cuts the party to a "Boss dying-words cutscene page". Jukebox automatically starts playing the boss's speech, layered with a heroic or sorrowful song. On this Page players see several pictures of the boss and the room setting the scene in a 3D way, ground level views, portraits, architecture. While the speech is heard, GM clicks and pops-up appropriate images to full screen with Shift Z. At the end of the speech GM cuts the party back to their current game page.
