Apologies for the delay, I recorded about 45 minutes of game footage in HD, when the race itself was only about 6 minutes or so.
It’s finished rendering in HD – on the time area of the bottom of the video, select 720p or 480p instead of the default 240p or 360p
It’s fuzzy in some areas – that YouTube’s rendering. If it doesn’t clear up later (YouTube renders the video in the background), I’ll upload a better version tomorrow (Saturday).
