Crazy what was considered fast internet 8 years ago

I actually really like Taran as a host. He's super informative and the way he explains it makes it obvious that he knows everything he's talking about, and is just making it nice and simple for us. Great video!

I actually really loved that you guys included actual examples of what some of the compression errors look like. Having seen those kinds of artifacts/errors in the past I now understand them a hell of a lot better than I did before, great job guys!

Fantabulously explained my good man.

Taran, your on screen presence is really improving, and you feel so natural in front of the camera. I like your attitude and the energy you bring to these videos. Keep up the good work!

wow that is really fast internet, It takes me about an hour and a half to download a 2.5 GB file

Awesome. Being an animator, this really does bridge the gap. Thanks for the clear explanation of the P,B and I frames.

You are getting much better at doing these videos! Great job, Taran!

good video, Give this man a burger.

2.5 gb in 5 mins, it takes me like 2 hours

Having Taran in these Tech Quickie episodes is actually pretty good. He's getting better, and I have to say his slower pace of delivering information (compare to Linus) is pretty good, considering the huge amount of information involved. Keep up the good work, team!

Linus should learn from Taran's video to improve his tech quickies. This is how it's done: -Speak like a normal person --it's EXPLAINED as fast as possible NOT TALK as fast as possible. -Tune down the jokes, which only adds "noise" (confusion) instead of clarity and sense --especially when talking 250 words/second. And finally, -The visuals need to actually add and compliment to what's being said (the explanation) instead of using silly, unrelated, 9gag-like images to compliment the jokes! Thank you Taran for the wonderful job at explaining what video compression is.

I enjoy Tarans coolness and ease at explaining. Great video

unreal what we can learn in 5mins! Tks Taran!

Smooth transition into the Fractal Design ad. Good work!

Good job bro, you are improving each time! Keep up the solid videos!

I've gotten so used to Linus that this is so slow

"High quality", "KZfaq"... Heh.

i did large calculation by collecting different datas. I will never forget this concept. Thank you

This explanation was fantastic - I'm amazed by how much I understand after just a few short minutes. Thank you!

KZfaq compresses the fuck out of videos making them ugly in the proccess.

F***, i am done! I have 5 fu***** mbps in download speed and just 0.5 mbps in upload. Welcome to the italian broadband my friend...

I'm actually using your video's to study for my exams (Audio/video stuff) The teacher could really use these video's during the courses, it's fast, it's crystal clear, and you actually show stuff, and stuff. I think I'm going to propose using these vids :)

This was one of the better as fast as possible episodes that actually covered the entire subject and a bit more. It seems like everytime Linus does an episode he focuses on speed by talking really fast and not giving too many examples making the video well. . . As fast as possible. All I'm saying is I would prefer the episodes be slightly longer in exchange for a more in-depth explanation with visual examples and analogies. Maybe next time you guys can cover what are floating point operations

"only 2.5gb in 5 mins" bruh..

"Now for an MPEG, sometimes called a Motion JPEG..." Who the hell researched this?

thank you for helping and well explanations👍

Teran to be the new boss. He is cool. He explains things more slowely and easily and seems he isn't going by wiki often. Like he said. He doesn't understand some of what linus says. Says it all really. Thanks Teran (I may be spelling yours wrong. Sorry😕) Also I use high bit rate for my gaming videos. They are normally 4GB size for a 20 min video but after rendering and slight compression it is 1.7GB. It takes KZfaq 20 mins to process and me 5-10 mins to upload.

Very informative video. Thank you for the free education!

Sometimes your video can go blurry like that if you have a slow hard disk or are reading off an external USB drive It never happens on my RAID array but it does happen on the backup drive, had to adjust VLC settings to 3000 ms or 5000 ms or whatever

Loving this guy, and all the technical stuff :)

Got a Fractal Design case, and I've been subscribed in months :D I do share a couple of videos too, to the ones I think can benefit from them :) Can't do much more than that :D Love the show! It's my favourite KZfaq channel by far :) Keep making these awesome videos, and I dont mind the adverticememt, actually they can be quite fun at times :D Keep making these! See you in another episode :)

A MPEG and MJPEG is not the same thing. MJPEG is a movie where every frame is a I-frame. 3:40 thats how it worked 1993 when MPEG 1 was relied. The thing is that the B frame referates the last I frame, and the P frame referates the nearest B frame. Mpeg 2 (and 3) is very similar. The order is always I-B-B-P-B-B-P-B-B-I. So every 9:th frame is a picture. In MPEG 4 H-263 they change it up. Firstly they use more modern I frame compression. The one uses is similar to JPEG2000 that work with a very different method. Also, in MPEG4 H.263 the order of frames is chosen by the enocode, and also the B frame is removed using only better quality P frame (also makes it not possible to decode the movie in reverse, well at least not with out a lot of memory). Thats why mpeg 4 compress almost twice as good as mpeg 1 with the same quality. In early encoders the I frame was encoded once every second (unlike Mpeg 1 where its encoded about 4 times a second). Later encoders only use a I frame for every scene change. Today H.264 and similar encoders is mostly used. Its similar to H.263 but uses newer I and P frames, also with a lot more features. coming online soon H.265, that in turn is about twice as effective than H.263. So geting better quality with lower bandwith is posible, use a newer codec. 3:50. That is not compression artifacts, that just low resolution

Isn't it supposed to be discrete cosine transforms? 2:05

Good run-through, considering the "as fast as possible"-aspect. I knew it all because I am a compression nut who fiddled with XviD as a kid and with professional Intra-frame codecs as an adult.. now with a job in a certain field. I don't have much to add, but appreciate that you took your time to explain for people. Maybe you could've talked about lossy vs lossless compression, as every method explained here counts as lossy, but that'd basically be describing zip ;) Next up I propose a video about RGB vs rec.709 vs the new color space in the upcoming 4K-standard ;) I bet at least 10 people would be interested enough!

Probably Taran's best video so far

If I had Google fiber I would have a uncompressed 4k fireplace video running 24/7. Why you might ask? Because I can.

lol the video has 264k views h264 ba dum tiss k bye

Decades ago, I remember attending a talk at a film archive library where the speaker told us why their film stock had to be preserved on physical celluloid. They did the sort of calculation you did, pixel height x width x colour bits x frames per second. I walked away convinced that one feature film, let alone 100,000 would use more magnetic storage than any such institution could imagine or afford. It took only a few years before mpeg compression, faster CPUs, and high density storage totally solved the problem. Never underestimate progress!

Exactly the kind of video I was eager to find. People often don't realize that what ultimately gives visual fidelity and clarity to a video is bitrate, rather than just higher resolution. And, although we might think that KZfaq, Netflix or better yet BluRays or even 4K BluRays are among the best sources for good quality video, most people, including me up to a few minutes ago, don't know that the native bitrate of any given file should, in theory, be much higher than the highly compressed one used to give us a fairly good-looking video. Even the 128Mbps that 4K UHD BluRays are able to reach as a maximum for their 4K content, is just a fraction of the huge amount of date it would contain in theory. At this point I'm also assuming that the cameras people shoot content with, already chops off what should theoretically the bitrate be. In fact, most cameras don't exceed 100Mbps recording data rates, but according to this illuminant video, we now know that a single second of a 1920x1080 / 30p native video source, should supposedly have a native bitrate of like 178MBps (yeah, with a capital B), which is massive if compared to the shy 25 - 35Mbps (lower-case b) bitrate that most 1080p BluRays used to have. Thus even cameras certainly don't reach that quantity of data per second. So we actually get an heavily compressed image anyways. And now that 4K content is starting to become more mainstream by the month, the gap between native bitrate and the bitrate we're actually getting is even broader. I didn't do the math yet, but I'm assuming that a 4K video should have like x4 bitrate per each second compared to 1080p (at the same framerate). I hope we're going towards a future where having video sources with native bitrates will be feasible, with the help of much faster broadband internet speeds. What's is certain is that it's better to have an higher bitrate rather than higher resolution. Like a really good 1080p video will always beat up a low-end poorly compressed 4K video. Obviously if we were to compare an uncompressed 1080p vs an uncompressed 4K video, here the 4K one is obviously the winner. P.S. I ran into some troubles doing the math for it. I did 1920x1080 = 2.073,600 then 2.073,600x30 = 62.208.000 Then I assumed I had to multiply 62.208.000 (the quantity of pixels of 1 second of 1920x1080 @ 30p) by 3 bytes and it equals 186.624.000 So it didn't give me 177.98 (the result of the video at 0:30) Could you please explain me the correct last passage that will lead me to that number? Thanks :)

Ok ... , So when are you gonna tell us how to do it ? Smh

How does file compression work? Like putting a file into a .rar or .zip and then decompressing it. How can you download a small file but end up getting something bigger after decompressing it?

to me as a video editor/creator this is very interesting, more of these kinds of stuff please! ^-^

What a small world, I'm preparing for this year's lectures and what (or who) do I find doing a video on compression? Taran! I must say that the topic is somewhat familiar to me. If I were marking this video, I'd have to take points off for the "MPEG sometimes called Motion JPEG" answer, but great video! Way to go!

What would happen if somebody made a video that every single pixel are different in every frame and uploaded it to youtube or other sites?

Guys, watch this at 1.25x speed t make this guys slow speaking more bearable.

Awesome Work Taran! Keep up the good work :)

now this is a boon for me... i have got my exam tomorrow and i could not have found anything better thn this,,,,,,thanx,,,,,,,

2.5 GB in 5 minutes! SLOW! Wait till you come to India!

Like if you watch TechQuickie sped up with the HTML5 player.

I just realized that my Fractal Design Define R2 XL doesn't have any logo on it ;S so clean looking case. i love it.

Great stuff, very well explained! Keep up the good work.

what about .mkv files?

6 minutes and you didnt fucking tell us a single program to use for compression. 6 minutes wasted.

Gonna have an exam about this stuff tomorrow. It helped me, thanks!

THE BEARD IS BACK AND I LOVE IT!

Is that fast internet? Mkay... I went a big step from dial up to chello and then fibre sooooo.... www.speedtest.net/my-result/3680952035 I never knew mine was fast...

That not fast Internet i got 100mbit/s up and down.

I hate ads but you guys are so creative i wait to watch them now.

I think Taran does a fantastic job hosting some of these Fast as Possible.

The horror on your face is returning. Please address.

Great Job !!! ; D Awesome video, I love Linus but would like to see more of this guy explanation on techquickie, he's very clear especially in this more "technincal" bits, binary and software related explanations

I enjoy Taran's fast as possible vids

Loving these series of videos. Can you do one for comparison of wireless mirroring pc to tv? Ie. miracast, Apple TV, dlna etc?

Thanks for this perfect explanation!

super usefull for me, well explained! just love this explained videos, thank you guys.

That shirt fits you damn well. Props.

This video cleared a lot of thing for me. Thanks guys.

4K :D I enjoy watching Taran!

Yay!! Another episode by Taran :D This dude is awesome in Techquickie videos.

Let me turn the video setting to 4k to make Taran looks EVEN better.

Good explanation, well done!

I'm not even mad that at the lack of Linus, Taran does a really good work explaining things.

Sweet transition.

Temporal Compression was the thing I came here to learn. I knew it existed, but wanted a bit more info. Downloading some videos from youtube that are focused on audio if you know what I mean. And I was baffled when my 6 hour long playlist was only 20gb. Guess that's cause all the video is just 1 frame. Cool stuff!

Motion jpeg =/= mpeg. Motion jpeg is it's own compression format and is basically just a bunch of jpeg images with no interframe compression (useful for editing, but not distribution). With h.264 video (like this one) the macroblocks start at 16x16, but can be further broken into 16x8, 8x16, 8x8, 4x8, 8x4, and 4x4 depending on the encoding settings.

nice! you have improved a lot Taran :) it's a lot less boring and a lot more cachy man :)

Future Taran would call that dismal internet speed.

Thanks guys! Very helpful!

Just realized we can compress a lot of music losslessly ip yo 50% since they repeat a whole section 2-3 times

Does anyone around here even care about the subject being discussed? Seriously, who the hell cares which dude is narrating, let alone his mannerisms/appearance? He did a good job, speaking loud and clear and that's what matters. Message was delivered!

I love Taran!

Great vid as always!

Your speed is pretty standard for a tech focused company but whats really sexy about that test is the ping. Ive never seen ping that low

I just saw a commercial by a church while watching this video and the guy was waving around with sausages. Now I would like to know what he was saying.

whoo, good good video I really like how you present you ads , really like you are defining a new way of doing ads good works!

I like this guy,for some reason,he is good!

wow. that was great explanation. thanks!

Thank you! That was very helpful! :)

Love these videos!

Yay, my Blackmagic Pocket Cinema Camera shoots at around 500 Mbps! Love it!

Was very helpful! Thanks

how did i miss these videos?

AWESOME! Thanks guys

Very informative, would appreciate an uptade videiu though, as things have changed quite a bit in 5 years

Finally, you nailed it in terms of your beard looks!

Thank you so much for the video.

Thank you for the informational video.

very good explanation

fractal design is the best sponsor ever
