Understanding YouTube New Video Technology.

It is time to go behind the curtain and really talk about how YouTube new Video Technology works. YouTube is not particularly complicated for the end-users. But if you know sort of the way thinks, what is the general technical process.

YouTube new Video

Notice that the video is actually being compressed twice: once to make it small enough to upload, and a second time by YouTube for distribution.

You are going to be more effective at posing your own videos, this diagram indicates the steps postings the YouTube video and there is really one important point here. Which is your video is compressed twice on YouTube.

We start by making the video, then before can be uploaded to YouTube we have to do some compression on most videos. The format of YouTube is used for editing in less the video is very, very short and it is going to be large to upload to YouTube.

When we compress video file for uploading outside the YouTube. We try to actually make, feel small for users and not to try track quality very much. But when we compress for the YouTube. Our goals are different. We want to maintain as much of quality as possible because we know YouTube going to do another step compression before actually makes it ready for streaming and download.   This may seem little complicated but we are going to through all of the steps we need to know for how to compress videos properly.

The only thing to remember this point is the first round of compressions is really about to the maintain the quality and just make the video small enough, so that it is possible to upload to YouTube than its YouTube job to do the main compression taking the video down to the size is distributable at the end of the process represented by the PC there is also chance to add additional information.

Such as metadata, annotations, end add the certain amount of data and interactivity forms of links, on Your YouTube video. So, there is little peek behind the curtain in mind it is important to know sort of the way, the software thinks, to help you to make the decision later.

Formats in YouTube new Video Technology.

MPEG, MOV, AVI we call to all video formats, and it is really not that bad here I am on the help page, see the list all of supported YouTube file formatted and define them right now.

A format is a type or flavor of video, I often call it, a wrapper because that is different things inside the formats, consider a container each of these accept last to or extensions so, .mov   is quick time movie, and .mpeg is an mp4 video, and this is full list of containers or formats at that are supported in YouTube.

If your video is not in those formatted so, you need to go the process of changing or converting in those formats.

This help list very useful. All these letters designate simply the formats the container the videos goes in you have to match that YouTube uses Or else accept the video.

Recommended Formats and Settings for YouTube New Video Technology.

Now we are comfortable with formats or the containers that we can put our videos in we need to go step deeper and look at the what is really inside those containers.

Generally, refer to as codecs or mash-up code or decode, the algorithms, that actually make digital bits and bytes into the video image.

There is a very useful page on YouTube. That has all of setting in details now I am going to navigate there so, how to find it go to help menu.

  • Explore help.
  • Type encoding settings.

Or.

Visit for more detail. 

This is where you can see all of the details for recommended formats and settings for YouTube as we have seen in formats movie YouTube can accept fairly wise range formats the same goes with details settings.

The power of this page is to see the preferred settings, exactly how YouTube wants this video to be set up from the process point of view, I recommended checking this page periodically because the recommendations do change, so, if I have uploaded to YouTube. Say months or two, the first step of my process is to come to this page, just check it and see if anything is changed so, let’s go to the information briefly.

First, we have the container or we refer to formats and you see the preferred extensions is mp4 or MPEG file, then we have the audio codec. Which is AAC-LC you can see that you can use stereo surround?

7 YouTube new Video

Next, we go to video codec which is common codec called h.264. This currently is the very common algorithm in the coding video.

8 YouTube new Video

Next, YouTube recommended do not change the frame rate, you maintain whatever frame rate, that your video begins with.

Next, we have bitrates, just think bit rate is the width of video travels through.

It is not about the total size of the video. How much data per second. As you can see here each resolution on YouTube has different recommended bit rate and if you think about it, more pixels require more data per second.

Next, we go to the resolution you can see for each common sizes the exact resolution that YouTube prefers.

Finally, at the bottom we have link Learn how to (use resolution and aspect ratios correctly) and deal with aspect ratio and I think these pictures are very useful for see the result click on Video display example images link.

The over point is YouTube now wise screen so, you want to prepare video also invites the screen is assuming creating in that way in the even not creating that way.

You want to upload native 4×3 and then YouTube will naturally pillar boxes. Those are the black lines right and left of the image.

I think this is the most useful page on YouTube help.

De-interlacing.

13 YouTube new Video

  • The interlaced video has two fields for every frame.
  • Progressive video refreshes all pixels at once.
  • The “I” in 1080i means “interlaced”.
  • Quality is improved if you remove interlacing (or “de-interlace”) your video.

De-Interlacing.

If you really pay attention to YouTube instructions as well as many of the choices you have when exporting you are going to see this choice about de-interlacing I want to take the movement to really break down to the concept.

Because it is an important one, for making your video, look to the best, first of all before we are anything, what is de-interlacing. Here we have a good diagram of what interlacing is traditionally how television renders an image.

The idea of every frame of video. You actually have two fields. There every other horizontal line, of pixels. Tradition video does not actually capture the frame of video. It captures the fields separately all the pixels in one field and then all the fields the pixels another field the two fields together make the frame.

Which is called progressive video refreshes all pixels at once and it is mean that all of the pixels in a single form or both capture and refreshed at the same time.

When you see “i” in any format it means interlaced and likewise you see “p” it means progressive.

The catch here is that all computers monitor what you almost always going to play YouTube or progressive monitor however many videos camera shoot interlaced.

Therefore, de-interlacing or removing that interlacing priorate to compressions some time to same time as compressions can really help, your final video, so then you have a theory, in practice, it often comes down, to check the box, de-interlace but this is you do do that. You are telling the computer take this to fields and render to gather give a good progressive video, signals that will be better compressions for YouTube. You do not need whole all technical know how to work on YouTube but I think knowing something interlacing and de-interlacing truly helpful.

Understanding Resolution for YouTube New Video Technology.

YouTube like the rest of the video technology has moved very quickly to embrace high definition.

Understanding Resolution.

Understanding Resolution for YouTube New Video Technology.

YouTube started at 360X240.

Today, it supports higher resolutions.

Here you see a lot of common resolution from DV and standard TV 480 by 720 all up to 4K that considered digital cinema.

Understanding Resolution.

  • YouTube started at 360×240: it is true YouTube started at 360×240 at its maximum and often see the resolution named by the first number or the vertical pixels measurement so we see 360×240 described as 360p, 720p and so on.
  • Today, YouTube actually supports all of the resolutions up to 4K higher resolutions than any commercial TV. For instances, no one is going to have a 4K screen actually view the video. Ad many people who not have high enough bandwidth to actually view the video smoothly. so now we have overview I want to show how, as users, you can control that resolution and this should be comforting you video maker. So, let’s quickly shoot our YouTube interface.

Here we are in YouTube and I purposely searched for the video, that is available in 4K can actually call time-space 4K.

I am not even playing because I want to show to you, the choices here in your settings, and here you see how 4K video will look and will get us the true 4K but then we can choose any of those any of those formats that will facilitate that watching in the event that just targeted does not play smoothly at the highest resolutions.
