或るプログラマの一生

(This article is English translation of Japanese version)

I found that the video clips that I generated are not compressed very much. The compression ratio is 1.06 in case of AMV4/DR2. I think it is not good and have to search other clips.

I decided to use Tears of Steel, the author of MagicYUV suggested. (here)

I use frame No. from 11777 to 12076, the scene that a picket soldier fires machine gun to enemy robots.

The resolution of 4K version of Tears of Steel is 4096×1714. The number of pixels is slightly smaller than UHD (3840×2160).
