Yo its Josh and today we're comparing h.264 and h.265 encoding. Let's start
with a little skit we put together.
Hey Internet! Yea Sam? I want to watch this
live stream can I stream it in h.264 please? Are you sure that's what you want
to do? I think so yes no maybe yes yes I do. All right
Hey Sam. What Internet? Are you trying to watch something in 4k? Yes I want to
watch it in 4k my mom said it's all the rage. Try this.
Wow thanks Internet! Okay so that's really an oversimplification, I know the
tech guys will hate us for that one but we'll dive into it a little more here
Acronyms! HEVC, say that five times fast,
also known as h.265, stands for high efficiency video codec. It's a really
complex method of compressing your video content so that you can live stream and
watch videos online more efficiently, without affecting the quality. The
current encoding standard for video streaming is AVC ,advanced video codec, or
h.264. Which works great for HD streaming, but if you're looking to watch content
in 4k you may want a better encoding format . HEVC and AVC are called
codecs. Codec stands for compressor/ decompressor. To put it simply, a codec
takes light and sound from your camera and turns it into a digital format that
a computer can read this is known as compression. Then, eventually our
computers read it and play it back to us the way it was originally captured which
is known as decompression, and that's how you're watching this video right now!
The advantage HEVC offers is it takes less bandwidth to stream your
videos and in fact the quality is better because the way it compresses those
videos is more advanced. If you want to learn more about that read our blog post
in the description! You can see in this graph that if you're trying to broadcast
in 4k it would require almost twice as much
bandwidth using h.264 as it would for HEVC. So yes HEVC
compression allows us to more easily live stream 4k content but it requires
more advanced hardware such as the BoxCaster Pro to be able to compress the
data fortunately however it also means that viewers with h.265 compatible
devices will require less bandwidth and processing power to decompress that data
and watch a high-quality stream so that's a summary of the differences
between h.264 and HEVC but if you'd like a more in-depth explanation on how
they're actually are compressed then you can

questions for me you can contact me anytime here thanks for watching and
happy streaming!
