Glad you announced this, I would have told you to via QC if you hadn't.
I actually quite liked this video. E7 videos almost exclusively focus on the relationship between Renton and Eureka; I think this is the first one I've seen that has absolutely nothing to do with either of them, and has no shots of either of them. That alone makes it pretty unique and original, so you get points for that.
The pacing is really good. It's probably tempting for a song like this to do more long crossfades and to use generally longer scenes, but you kept up with the tempo really well and the video has really nice visual rhythm. I also like (for the most part) the glows you used to sync in the first half. It reminded me a lot of AceMan's
Beyond the Clouds, and despite the fact that I tend to look down on such obvious external sync, it worked really well because you had other things going on in the scenes themselves so the glows felt more complementary than overriding.
Also the scene at 2:52-2:54 was absolutely *perfect*. Great lead up to the climax, very appropriate.
However, I have quite a few things to complain about as well. For one, the quality was a huge downer; even at that (extremely) low resolution, the video looked pretty bad. I would have really liked a higher resolution and some heavier VDub filtering. The stray frames you mentioned were distracting and did tend to kind of jar me as I was watching the video; I feel like it would have been worth it to go back and fix those frames and re-render everything out. Also, be careful about mouth flap. You had quite a few scenes where the characters' mouths were moving but they didn't match up to the lyrics, so I assume you weren't trying for lip sync. Such scenes were distracting.
That aside, this was a very good video. I love E7 so it's nice to see something different. Keep up the good work.
