Фон видео HTML5 не загружается

Новичок здесь еще раз пробует вещи, выходящие за рамки их набора навыков, чтобы расширить набор навыков.

Я пытаюсь воспроизвести циклическое видео в качестве фона для моей маленькой формы (новичок пробует что-то новое в качестве учебного упражнения). Все, кажется, загружается, ссылки/пути верны, файлы загружены в свои папки и т.д. Я искал опечатки и проверял свои скобки, двоеточия, точки с запятой и т. Д. Я зашел так далеко, как только мог, но я еще не совсем "там", как на видео играет не так, как надеялся.

Примерный пример здесь
