Team Acer TrackMania videos
Team Acer's Kalle "frostBeule" Videkull has the answer for your TrackMania video action needs: his youtube page. There you'll find new videos uploaded regularly, featuring not just TrackMania but other games too.
"The content I provide on my Youtube channel is mostly I'd say a mix of highlights from my stream at Twitch.tv, which for example can be runs of personal bests, or other things such as comebacks in matches, spectacular fails and so on. But the content can also be videos where I edit together good replays that I've saved, you'd call these "frag-movies" if it was an FPS game I suppose. However I don't really do those kind of movies that often though, as they generally take up quite a lot of time for me, and I prefer to spend that time on competitions instead. But I have lots of ideas and once in a while I will do something with those, that's for sure.
