I checked this video out for the song. I love to watch amvs set to my mother language (other than Rammstein or E Nomine

), as this ehances the video-atmosphere to me considering I can relate more to them and thus they feel a lot more emotional to me. That aside, I still think german is one of the most beautiful languages worldwide and not only because I can understand it.
And while not expecting anything, this amv was just great. It didn't only portray the lyrics really well by scene choice, but also had an impact on me editing-wise. The editing enhanced the emotional aspect and worked really well. I'll keep this video and watch it a few more times
I personally love the animation style by the way. It's just something else, regardless of the characters looking ugly.
The downsides are probably the technical aspects.
DO NOT F****** ENCODE YOUR VIDEO IN HD UNLESS YOUR FOOTAGE HAS WELL ENOUGH QUALITY TO NOT LOOK ALL BLURRY. This trend is really annoying as most videos in 720p I've seen so far looked like crap. This is one of them.
Why is the video letterboxed? You should have just used a natural frame size for the anime.
Please do not add hard subs on your amv. If you really wanted your video to include subtitles for the foreigners to understand, you should have encoded it as .mkv with a softsubstream or something similiar. To me they felt really distracting and I always had to stop myself from looking at them instead of the video. They are useless to me anyway, considering I understand the lyrics and I wish I could have just turned them off.
Your video seems also to be misinterpreted as 8 Minute Video as you mentioned yourself. This looks like an encoding error to me. I watched the file with KmPlayer and it also showed up as that long. Yet, it suddenly stopped when the actual video was over. A re-encode with slightly different settings may have fixed the problem, but I'm not sure where exactly you did something wrong.
Looking past the technical errors, this was a really enjoyable video.
