ridiculous question about my last short video

Some peoples on internet have really stupid questions sometimes... seems they dont really think before to type... the first one was one of my friend on Weixin (chinese whatsapp) " Hey, i saw the video, it was great!! But i have question... the guys you killed they are all in pixels... is that a codec problem or my player have problem?"Ok, that question was cute indeed... the next one was superb!!!!! i got it 10 min ago!:that one deserve a screenshoti loved it!!!!!  -_-
