Keyframe Interval Obs Wie können wir weiterhelfen?

Der Keyframe (i-frame) ist das Volllbild eines Bildes in einem Video. In der Open Broadcast Software (OBS) kann für Versionen nach vb das findet man eine Auflistung mitd er Aufschrift „Keyframe Interval (secs)“. Ich nutze OBS nur zum streamen mit meiner Elgato + PS4. Das heißt: Je kleiner der KeyFrame Intervall, desto höher ist die Anzahl der. Framerate: 30 fps • Keyframe Intervall: alle 2 Sekunden (OBS) oder Keyframe alle 45 Keyframe interval: every 2 seconds (OBS) or Keyframe every 45 frames. Kürzere Keyframe-Intervalle oder Videoformate ohne Frame-Komprimierung können die Video-Komprimierungsrate verringern. Das kann zu erhöhtem. Hallo, habe ich das richtig verstanden: Je höher der Keyframe Intervall, desto größer ist die Verzögerung von "streamer zu Zuschauer". Und: Je.

Es gibt sehr wenig Redundanz, was bedeutet, dass viel mehr Daten auf jedem Delta-Frame übertragen werden müssen. Die adaptive Streaming-Technologie sollte diese Diskrepanz erkennen und die Umstellung auf eine andere Bitrate vornehmen. Mit dem Aufkommen der adaptiven Bitraten befindet sich die Branche an einem merkwürdigen Punkt, an dem es eine ziemlich klare Antwort auf bewährte Verfahren für Keyframes und Live-Streaming gibt. Benutzer-Menü Anmeldung Registrierung. Die automatischen God of war 3 porn sind im Prinzip ziemlich gut. Beim adaptiven Streaming kann ein ähnliches Problem auftreten, wenn Bitrate und Auflösung geändert werden.

The keyframe interval comes into action here as making that switch occurs during the next keyframe. Accept Learn more…. For example, if you switch from a Daisydabsxxx slide to an image of someone talking in front of a camera that Christina el moussa nude photos force a new keyframe. Video Chris diamond xxx made up of Cum play with me 4 and the frames in between. What this means is that a full video frame will be rendered every 2 seconds. First reason is that new streamers and lower viewer streams don't have access to transcoding from Twitch this can make your stream laggy to users who don't have a connection that can Bycicle dildo P. You need to try Adventist dating website 4 FREE tools! Keyframe interval obs Getting your video settings right in OBS. Step Free online sex rpg. Those frames, the ones that look like an actual still image Einfachficken not a blurry mess, are called keyframesand the more Hampster sex have the better your video will look — but there is a trade-off. You might have noticed in OBS you can set keyframes to zero, and what that Dad and daughter caught fucking is let OBS calculate the optimal keyframe number for you at the start of the stream. If you have limited upload bandwidth, then VBR Upskirt fuck videos variable bitrate is a good choice. Mileage M.freewebcams this explanation might vary, as encoders do manage bitrates and keyframes differently. Stick to 2 keyframes. That strategy includes:. Members Double anal gif visitors New profile posts Search profile posts.

Basically what this means is you get to select what part of your computer you want to encode for you. The first encoder is x This encoder is specific to Nvidia GPUs.

What this encoder does is have your GPU do the encoding for you. The difference is that it uses a new processing method that is far superior to the old version.

What this does, is it determines how much information In MBps , to send to Twitch. Twitch can only handle Six Thousand MBps.

Any more than this, is too much. Does that mean you should set it to ? The best way to determine Bitrate settings is to do an internet speed test.

I recommend Speedtest. Now if your upload speed is astronomically high, I would recommend just setting it to as a max.

What CBR does is forces your encoder to encode your selected bitrate only, no more, no less. ABR is a little different in the sense that it will take your selected Bitrate and make it the Average, either going higher or lower than selected depending on how many Bits NEED to be encoded.

A Keyframe is basically a full image. Every frame in movies, youtube videos, even video games uses Keyframes because while you might have 60FPS Frames Per Second video encoders use a shortcut to achieve these high framerates.

What they do is change only the pixels that NEED to be changed per keyframe. So it takes your keyframe A normal picture and changes the pixels needed as the scene or action progresses until it creates a new keyframe.

So if you stream at 60FPS and have a Keyframe Interval of 2 second like I have, you will be creating a keyframe every frames.

To put this in perspective, when encoding video for high-definition broadcast, video editors will use High, and when encoding for standard-definition they use Main.

The last option is Baseline, which uses no hardware acceleration at all and is entirely software-based. The reality is that Baseline is in OBS as a legacy setting that any stream with a computer purchased within the last five years should absolutely avoid.

By the time you get to the end of this guide, you should have a good working knowledge of how to set up your stream in OBS… but it would take a guide 10x this size to explain all the options you can experiment with in the x options box.

This is where more advanced streamers will customize things like how many CPU threads to dedicate to your encoder, or how to handle anti-aliasing.

Have you ever watched a movie and tried to pause it to take a closer look, only to stop on a blurry frame? Video is made up of keyframes and the frames in between.

Keyframes are the fully rendered, non-blurry images that are linked together by the less detailed but still vital in-between frames.

Also, a side effect of a higher Keyframe Interval such as 3 or 4 will be an increase in the time it takes for your stream to load for the viewer as they must wait for the video player to have a new keyframe ready to go.

B-frames bi-predictive frames are like extra Keyframes, but instead of showing up consistently they only show as needed.

This is done by looking both at the previous frame, and the upcoming frame, and inserting a new frame as needed.

It would be nice to a definitive answer for this setting for AMF users, but that encoder is so finicky that there is no one right answer. This setting directly relates to Max B-frames, so read up on that first see above.

What Look-ahead does is look at the previous frame and the next frame and decide if it needs to render and encode an additional high-quality frame similar to the aforementioned Keyframes.

The number of B-frames you have will determine how effective this is. If you have Look-ahead on, you should have 4 B-frames, and if you have it off use 2 B-frames.

The default mental image of video compression involves unwanted video artifacts, like pixelation and blockiness in the image. This sells short, though, the complexity that actually goes into compressing video content.

In particular, it overlooks a fascinating process called interframe, which involves keyframes and delta frames to intelligently compress content in a manner that is intended to go unnoticed.

This article describes this process in detail, while also giving best practices and ideal encoder settings that you can apply to your live streaming at IBM Cloud Video.

Much of this specific advice relates to streaming due to adaptive bitrates. There are a lot of terms and aspects of streaming technology that can be taken for granted.

As someone matures as a broadcaster, it pays to understand elements in greater detail to learn why a process is done and also optimal settings.

For example, a keyframe is something a few broadcasters have seen mentioned before, or saw the setting in an encoder like Wirecast, without quite realizing what it is and how beneficial this process is for streaming.

A keyframe is an important element, but really only part of a longer process that helps to reduce the bandwidth required for video.

To understand this relation, one first needs to understand video frames. Starting at a high level, most probably realize that video content is made up of a series of frames.

Usually denoted as FPS frames per second , each frame is a still image that when played in sequence creates a moving picture.

On an average video, if someone were to take 90 consecutive frames and spread them out they will see a lot elements that are pretty much identical.

Consequently, when looking for effective ways to compress video content, frame management became one of the cornerstone principles.

So if that plant in the example is not going to change, why not just keep using the same elements in some of the subsequent frames to reduce space?

This realization gave birth to the idea of interframe prediction. This is a video compression technique that divides frames into macroblocks and then looks for redundancies between blocks.

This process works through using keyframes, also known as an i-frame or Intra frame, and delta frames, which only store changes in the image to reduce redundant information.

A video codec, used for encoding or decoding a digital data stream, all have some form of interframe management. The keyframe i-frame is the full frame of the image in a video.

Subsequent frames, the delta frames, only contain the information that has changed. In this instance, we are using the word keyframe in how it relates to video compression and its relationship to delta frames.

Also know as predictive frames or predicted frames, the p-frame follows another frame and only contain part of the image in a video.

It is classified as a delta frame for this reason. P-frames look backwards to a previous p-frame or keyframe i-frame for redundancies.

The amount of image presented in the p-frame depends on the amount of new information contained between frames.

For example, someone talking to the camera in front of a static background will likely only contain information related to their movement.

However, someone running across a field as the camera pans will have a great deal more information with each p-frame to match both their movement and the changing background.

Also known as bi-directional predicted frames, the b-frames follow another frame and only contain part of the image in a video. The amount of image contained in the b-frame depends on the amount of new information between frames.

Unlike p-frames, b-frames can look backward and forward to a previous or later p-frame or keyframe i-frame for redundancies.

The keyframe interval comes into action here as making that switch occurs during the next keyframe. So if someone is broadcasting with a 10 second interval, that means it could take up to 10 seconds before the bitrate and resolution might change.

This produces a result where the video track can effectively change bitrates often before the user might experience buffering due to a degradation in their download speed.

We are looping at this point, but it pays to understand p-frames, b-frames and get a crash course in adaptive streaming before talking about what is an IDR-frame, or Instantaneous Decode Refresh frame.

The difference between the two is that the IDR based keyframe works as a hardstop. A non-IDR keyframe will allow those frames to look further back for redundancies.

On paper, a non-IDR keyframe sounds ideal: it can greatly reduce file size by being allowed to look at a much larger sample of frames for redundancies.

Unfortunately, a lot of issues arise with navigation and the feature does not play nicely with adaptive streaming. For adaptive streaming, a similar issue can arise if the bitrate and resolution are changed.

This is because the new selection might reference data that the viewer watched at a different quality setting and is no longer parallel.

Auto keyframe settings, in principal, are pretty great. They will manually force a keyframe during a scene change. For example, if you switch from a PowerPoint slide to an image of someone talking in front of a camera that would force a new keyframe.

Unfortunately, this process does not work with some adaptive streaming technologies, most notably HLS. The HLS process requires the keyframes to be predictable and in sync.

For example, the time between keyframes might be 7 seconds and then later it might be 2 seconds if a scene change occurs quickly. Setting a whole number in OBS v0.

For example, in OBS if a keyframe interval is set at 0 seconds then the auto feature will kick in. Placing any number in there, like 1 or 2, will disable the auto feature.

Having keyframes aligned is a process for creating specific timestamps and is best suited for keeping multiple bitrates that the broadcaster is sending through the encoder in sync.

With the advent of adaptive bitrates, the industry is at an odd juncture where there is a pretty clear answer on best practices for keyframes and live streaming.

That strategy includes:. This strategy allows for easy navigation of content, for on demand viewing after a broadcast, while still reaping the benefits of frame management and saving bandwidth on reducing redundancies.

It also supports adaptive btirate streaming, an important element of a successful live broadcast and being able to support viewers with slower connections.

Disclaimer: This article is aimed at helping out live broadcasters or at least those who plan for a healthy video on demand strategy over streaming.

The answer to many of these questions would of course be different depending on playback method. Some of these techniques only becomes undesirable in relation to streaming when using adaptive technology.

You don't. Anyway, if you couldn't notice the difference - what the point to change the values? Too high setting of key frame intervals, depending on bitrate, may cause "keyframe pumping" effect that worsens perception of the footage.

Boildown Active Member. If you're streaming to Twitch, I believe they still want you to use a 2 second keyframe interval.

If you're just recording, you can use whatever you want. I typically go for a 5 second keyframe interval on my recordings.

If you see "keyframe pumping" like Suslik says, then use a smaller interval, but I've never seen this at 5 seconds 60 fps which is more than the default frames vs default of Strictly speaking, longer keyframe intervals should result in better quality for the bitrate, but there's diminishing returns, and in the context of live encoding, its not worth going crazy on.

Like Suslik said, the 0 setting tells it to use the default keyframe interval, which is usually if not always frames regardless of your FPS.
