Star Size Comparison 2


Дорогой мир,
Давай поговорим о времени.
Когда я загрузил мое первое видео на YouTube 7 лет назад, Я бы никогда и не подумал, что оно получит так много внимания. Имел много обсуждений, встретил новых людей, продолженных, чтобы сделать видео о вещах, которые заинтриговали меня. Или испытал эффекты.

Я наслаждался им много, и я все еще читаю каждый комментарий, который появляется. И они продолжают приходить. Я очень рад, что начал это хобби. И я смущен вниманием.

Ну, поскольку время проходило, я находил все меньше времени для работ над видео, боролся с другими вещами в жизни и задался вопросом, найду ли я когда-нибудь время снова.

Но я всегда знал одну вещь:
Я кое-что должен Вам. Все время люди спрашивали о продолжении к сравнению размеров звёзд. И да, я пообещал однажды.
Я держу свои обещания. Так, каждый раз, когда я находил время в прошлом году, я тратил его на проект. И вот он.
Я надеюсь, что Вам понравится. Я пытался сделать его в немного другим способом. Любопытствую об отзывах. Я знаю, что едва ли буду в состоянии победить музыку из первой части, но позвольте мне сказать, Вангелис Альфа — часть, которая очень дорога моему сердцу, я всегда держал её в памяти.
Все еще ищу возможности контакта с музыкантами.
Я не знаю, что принесёт будущее, но я надеюсь, что мы получим вести друг от друга. Наслаждайтесь!

Why is TV 29.97 frames per second?


I look at the historical quirks which gave us TV at 29.97 frames per second. In North America at least. Its a comfortable 25 fps in Europe.

More on that thing I mentioned at the end of the video here:

Here is the spherical video I was making with Henry Segerman which made me research NTSC frame rates in the first place:
www.youtube.com/watch?v=Yp12c3-IL-I

Yes, technically, if you divide 4,500,000 by 286 you get a horizontal frequency of 15,734.26573 lines per second. That matches a frame rate of 29.97002997002997… and so old TVs used 30/1.001 = 29.97002997002997…

CORRECTIONS:
— A lot of people pointing out that increasing the number of horizontal lines without increasing the bandwidth would be a loss of resolution. Which is a good point.
