How Video Compression Works

Have you ever wondered how video streaming is possible? Let's think about how big a typical 1080p video is: 1920x1080 pixels, 24-bits each, 30 frames per second... That's almost 1.5 gigabits per second. How can you transmit that much data, over the air, in real time? The answer is video compression.

It was such a nice surprise to see that my video was recommended by Marques Brownlee on my wedding day. Thank you Marques and everyone who came here from his channel! This has been a great wedding gift.

[@michaelbaldwin99]

Congratulations on the wedding!

[@snowmyr]

Happy 0th anniversary. This was a very informative video and I hope this exposure gives your channel a boost.

[@asyraafmz1877]

Congratulations on your wedding! Cant wait to learn all the machine learning stuff on your channel. Keep up the good work!

I can't imagine how you explained this so easily. You made it so easy and understandable that i can't believe... 😊 Thanks for making. Please explain more concepts of AI like this.

[@NovemberBegin]

Tbh Marques was right--this is a very clear and concise explanation of video compression. It even introduces technical features like I-frames

[@Aanandkrs]

Your videos have remarkable quality. I especially love the ones on AI. Was looking for a good channel to learn about AI as well. I'm glad Marquess brought me here... You definitely earned my sub...

[@19ozzie83]

Congrats on the wedding! Great video!

[@arpitkumarmishra6220]

Watching your video, after the marques mentioned about block motion estimation, and on searching the same on yt, ur video came first

[@eyokfla]

[@ling6701]

Thanks for the explanations. At 1:22 though, I believe it should be saying "temporal (inter-frame)", and not "temporal (intra-frame)".

[@nirshadnijam2291]

Massive respect to the pioneers behind this technology. It is insane how humans are capable of thinking like and implementing it on a computer. Crazy!

Marquees Says hi ;)

[@johneygd]

It’s just sooo mind blowing how all those video compression formats works,it just blows my mind how the decoder reconstructs and approximates the original frames back,so what we are seeing on tv is not the original footage but an approximated version of it,heck our tv’s can even add extra new frames between wxisting frames to averagely more close approximates mother nature in terms of motion, so what if the footage was only recorded at 12 frames per second,then your 100hz tv can add 8 new frames between 2 existing frames to smooth up the motion,it’s just mind blowing what can be done with less,😁

[@tofu3317]

He's gonna be so happyyy

[@wongsanggar]

Great explanation! I come from MKBHD test.

[@hdmoviesource]

Hi, is it possible to place more emphasis on predicted frames? In the case of movement for example? So smearing is less of an issue?

[@TheJhonVincent]

I would like to learn more about video compression.!

[@alexijohansen]

How does the motion of blocks to motion vectors work?

[@soengineer]

Great explanation Is there a detailed explanation in the form of a series of video lectures about h265

[@skobanemusic5752]

Thank you.

[@rishabhsingh7041]

Would temporal compression be a lossy one or lossless ?

[@Jstroman221]

You're about to blow up.

[@vincent_hall]

Working on this myself now.

[@shahravi7390]

guess who ? MKBHD linked this video ! Your channel is going to grow rapidly dude !!

[@Louukang]

anyway you can somehow implement this into obs studio for streaming or give tips on how to get good quality on it?

[@Bugside]

You sound like a nice person, just saying (good video too) congrats on the wedding

[@spider853]

Aren't motion vectors inverse? like the next frame takes data from previous frame so there might be a case where 2 regions take data from same region? The way it's shown here looks like the regions are scrambled by motion and you end witht a lot of empty spaces (like 100x100 regions will result in 1:1 100x100 regions which I guess it's not the case in real scenario)? correct me if I'm wrong

[@azimakhtarshenas2501]

hey Leo you are amazing, I do want to work on video coding, do you have any ref or source by which I can speed up my process???

[@avramukk]

good job

[@aditya27_raj]

Mkbhd has shared this video, it’s pretty soon going to get over Million views 😂

[@lollipopnik]

have you tried to upload video, where each frame is completely different picture? will it compress?

[@Archer-hg9rw]

I've been lately noticing a little bit of stuttering in movies on Netflix could the compression of the videos make them less smooth?

[@selami32]
