The video I got from here: https://docs.zap.works/studio/tutorials/streaming-video-in-the-3d-view/
It’s very simple. The “test.zpp” file is simply an empty project. The “testWithVideo.zpp” is a project with a video. The “testVideoRemoved.zpp” is an empty project that once had the aforementioned video. Notice that “testVideoRemoved.zpp” has the same size as “testWithVideo.zpp” even though it has no video.
