Best Ibs Settings for Upload Less Than 1mb
When first using OBS you lot might be overwhelmed by the sheer number of options available and the configuration required. In this guide nosotros'll go through some of those options, and what you'll want values to use.
Output Settings Tab
Generally speaking the most important configuration options are under the 'Output' tab under 'Settings'. In this tab yous can configure the majority of both video and audio options.
First we'll want to enter the 'Avant-garde' fashion, as this gives us the power to more tightly melody our OBS settings.
Encoder:
Depending on your hardware you might want to enable hardware encoding. This can either be NVENC or QuickSync. Turning on hardware encoding will reduce the CPU usage, however it can result in slightly lower visual fidelity.
If you don't have hardware that support hardware transcoding, or you want higher visual fidelity, and so go with the x264 option.
Rate Control:
Charge per unit control will determine how consequent or inconsistent your bitrate volition be. CBR or constant bitrate is the nigh widely used and accepted method. Generally speaking CBR also provides the highest visual fidelity, as information technology volition aim to maintain a consistent specified bitrate. Notwithstanding, the downside to this is that it will require higher bandwidth.
If you have limited upload bandwidth, and so VBR or variable bitrate is a good pick. Just make sure the platform you lot're streaming to supports it.
Bitrate:
Your bitrate will be adamant by a number of factors including:
- Video resolution
- Video frame rate
- Upload bandwidth available
The below table gives you a rough guide on what bitrates to use.
| Video Bitrate | Audio Bitrate | Resolution | |
| 1080P | 6,000Kbps | 128Kbps | 1920×1080 |
| 720P | 3,000Kbps | 128Kbps | 1280×720 |
| 480P | 1,000Kbps | 128Kbps | 854×480 |
| 360P | 600Kbps | 96Kbps | 640×360 |
| 240P | 300Kbps | 96Kbps | 426×240 |
We get into much more detail about how to decide your ideal bitrate in this article about BPP or bits per pixel.
Keyframe Interval:
For live streaming you will desire to set your keyframe interval to 2. What this ways is that a full video frame will exist rendered every 2 seconds. If you want to learn more about keyframes, caput over here.
CPU Usage Preset:
CPU Usage Preset is only relevant if yous're using software encoding, x264. It will determine how much CPU ability you wish to utilize to render the video. The slower you lot fix it, the college the video quality, however the higher the CPU usage is. Generally the sweetness spot is 'veryfast'.
Profile:
In most cases yous will want to set up 'Principal' as the profile. You can get down the rabbit hole and learn what each of the profiles exercise, and what different features they support. You lot can read more almost information technology here.
Audio:
Setting upwardly audio is relatively straightforward. All you actually need to exercise is set an audio bitrate. Nosotros recommend at to the lowest degree 128, equally whatsoever lower the audio can sound quite compressed. If you meet any sound sync issues, you lot tin set an sound delay to align sync. You can check out our guide on how to practice that here.
Video Tab
Side by side nosotros'll go to the 'Video' tab. In this area nosotros specify what resolution we want the stream to be output at. For the highest visual fidelity you will want your base canvas to lucifer your output resolution. Even so, if y'all're capturing your whole desktop, and it's 2K or higher resolution, you might want to accept a scaled down output resolution to something more manageable like 1080p or 720p.
Terminal Thoughts
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 exist dropping frames. In OBS if you look at the bottom correct of the application you volition discover a 'Dropped Frames' value. If this is anything other than 0% then your stream volition accept some issues.
In that location could be a number of things causing this effect. We've made a guide that y'all tin follow hither on how to stop dropped frames.
