Thanks for collecting these, Silvia. Looking through the list, it's clear that all of these have a non-trivial layout of the multiple video tracks. For example, Mlbtv_02.jpg is a baseball video with plenty of overlayed information together with the extra video track. The extra video track has a special border that fits with the rest of the presentation. Transhud.jpg also has special UI around the overlayed video track, and it appears as though the many overlayed video tracks in Winclip.jpg has at least a thin black border. The conclusion I draw from this is that the effects "people" want are only really feasible with multiple <video> elements that are positioned and styled with CSS. In other words, for multi-track video, we need only really consider the technical solutions that link together several sibling <video> elements. -- Philip Jägenstedt Core Developer Opera Software
