In 2024, you should have seen 4K videos in private.
Many platforms continue to do articles in the quality of the video.
Some support 8K 120 frames.
Some are blue light, color world, real-time audio, and dubbing.
These are very advanced technologies.
We are also constantly updating the shooting equipment,
improving the quality of the program,
and trying to give you better content.
But I don't know if you have noticed a detail.
The video we finally sent on the platform,
the video you saw,
it's blurred.
It's not as clear as before.
Is this an illusion?
The answer is no.
This is a very profound problem
Even in the future, I can say
The quality of the video we see
It's very likely to be worse than in 2020
So good
In this program, we will talk about
Why have all kinds of technologies been developing over the years
The quality of the video we see on the Internet
Not rising, but falling
To understand why the global video quality is declining
We must first understand
is that any video broadcasted on the Internet
has been greatly compressed.
It's to
reduce this thing called horse rate.
You know, if the video data is not compressed at all,
a 4K regular video
will take 44GB in a minute.
Your 1TB top-of-the-range phone
can only shoot for 23 minutes.
You have to buy another phone.
It's full.
No one can stand it.
In terms of practicality and sharing,
high compression rate coding
has become a must-have option.
I don't know if you've heard of
This is a code widely used in the high-definition era
Its purpose is to help you
To make a better video
Under the premise that the picture looks good
to compress the video to a large size
Its compression rate is terrible
It can compress the data of 4K video in one minute
to about 400MB
