Since I got some extra spare time left I've been tinkering a bit with my favorite video editing software and I've combined the three HD demo videos in only one video, seamlessly integrating the audio and video transitions between the three videos and mixing the audio tracks together at the end of each part [e.g. you can actually hear the dragon roar, which we left outside the dungeon at the end of the 1st part, at the beginning of the 2nd part]. I have also lowered the original bitrate from CBR 35Mbps to CBR 20Mbps, which is the standard HD720p bitrate. Basically the HD videos available for download on joystiq.com are a little too heavy, the video bandwidth doesn't need to be that wide for this video quality/format. Hence the combined video size is a little below the total size of the three videos, with no image quality loss. Since its bitrate is lower, the video can also be played smoothly on mid-range PCs which can't play HD videos.
Combined video size: 3,0Gb vs. a total 3,3Gb of the original videos
Length: 21'41"
Container format: MP4
Video Codec: AVC
Audio Codec: AAC
Audio bitrate: 256kbs @ 48Khz
Video bitrate: CBR 20Mbps
http://www.2shared.com/video/83RO4m0n/SkyrimDemoSample.html is a sample of the video, it's the transition from the 1st to the 2nd part. And before you ask, no, I can't do absolutely nothing against the original screen tearing.
Are you guys interested in this? If so I can upload it somewhere, provided I won't break any copyright rules, which I'm very concerned about. Thoughts?
