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.
We go into much more detail about how to determine your ideal bitrate in this article about BPP or bits per pixel. For live streaming you will want to set your keyframe interval to 2.
What this means is that a full video frame will be rendered every 2 seconds. If you want to learn more about keyframes, head over here.
It will determine how much CPU power you wish to use to render the video. The slower you set it, the higher the video quality, however the higher the CPU usage is.
You can go down the rabbit hole and learn what each of the profiles do, and what different features they support. You can read more about it here.
Setting up audio is relatively straightforward. All you really need to do is set an audio bitrate. We recommend at least , as any lower the audio can sound quite compressed.
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.
This makes b-frames more efficient as opposed to p-frames, as they are more likely to find redundancies.
However, b-frames are not used when the encoding profile is set to baseline inside the encoder. In regards to video compression for live streaming, a keyframe is set inside the encoder.
The keyframe interval controls how often a keyframe i-frame is created in the video. For an example of how keyframe intervals work, if your interval is set to every 2 seconds, and your frame rate is 30 frames per second, this would mean roughly every 60 frames a keyframe is produced.
In terms of setting a keyframe interval, it varies from encoder to encoder. Wirecast is different as the interval is actually denoted in frames.
For the vMix encoder, one needs to first click the gear icon near streaming, which opens the Streaming Settings. Setting the keyframe interval in version v0.
For XSplit, keyframe interval is a component of the channel properties. To the far right of this is a gear icon.
This will allow someone to specify the keyframe interval in seconds. Mileage in this explanation might vary, as encoders do manage bitrates and keyframes differently.
This can be reproduced when using the same exact average bitrate and keyframe interval between them. The reason for this is because, in part, due to the fact that the delta frames have a ton of information to share in the jumping example.
There is very little redundancy, meaning a lot more data that needs to be conveyed on each delta frame. Consequently, the added bandwidth that is needed for the additional information contained in the delta frames results in the quality being reduced to try and keep the average bitrate around the same level.
The reason it was suggested is because, for a standard More From Medium. Advanced OBS settings: What they are and how to use them.

BEST STREAMLABS OBS STREAM SETTINGS 2020 [COMPLETE] As a result, the Lvinpress might be trying to watch content that is too high of a bitrate versus their download speed. Okasian girlfriend speaking, longer keyframe intervals should result in better quality for the bitrate, Buffy tyler 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, Lena paul blacked full is usually if not always frames regardless of your FPS.

The reason it was suggested is because, for a standard To explain more, a player can not start playback on a p-frame or b-frame. So using the 10 second example, if someone tried to navigate to a point that was 5 seconds into feed it would actually shift 5 seconds back to the nearest keyframe and begin playback.
This was considered a good trade off for smaller bandwidth consumption, although for reference DVDs elected to use something much smaller than 10 seconds.
However, for live streaming, the recommended level has drastically dropped. The reason for this is the advent of adaptive bitrate streaming.
Thanks for taking a look at my beginners guide for Streamlabs OBS. In this guide I will show you the basics of getting your stream up and running using Streamlabs OBS software.
This is the password that the software uses to broadcast to your Twitch Channel. You will find your stream key as the first option in this window.
After adding your stream key into the Streamlabs OBS software we can then move onto adjusting the settings to get a quality stream! The most important thing when it comes to streaming is the hardware you use to encode.
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. We recommend at least , as any lower the audio can sound quite compressed.
If you run into any audio sync issues, you can set an audio delay to align sync. You can check out our guide on how to do that here.
In this area we specify what resolution we want the stream to be output at. For the highest visual fidelity you will want your base canvas to match your output resolution.
By using the values suggested in this guide you should get a decent quality stream being broadcast by OBS. However, if you or your viewers are noticing stuttering or a weird frame rate of your live stream, you might be dropping frames.
