Mastering the Encoder Settings for Rescaling
To achieve flawless rescaling, it’s crucial to fine-tune your encoder settings. Here’s a comprehensive guide to help you optimize your encoder configuration:
Encoder Type and Output Resolution:
Choose an encoder that supports the desired output resolution (1920×1080) and consider its efficiency. The x264 encoder is a popular choice for its high quality and efficient compression.
Bitrate and Profile:
Set the bitrate to 6000kbps or higher to ensure the quality of the scaled video. Choose the “high” profile for optimal encoding performance.
Preset and Level:
Select the “slow” preset for the best quality, but be aware of the increased encoding time. The “3.1” level is suitable for 1920×1080 resolution.
Advanced Settings:
Consider setting the following advanced parameters for further optimization:
| Setting | Value |
|---|---|
| Rate Control: | Constant Rate Factor (CRF) |
| CRF Value: | 18-23 (Higher value = lower quality) |
| Keyframe Interval: | 240 frames (for smooth playback) |
| B-Frames: | 0 (for better quality) |
Optimizing Encoding for Rescaling
To ensure the best quality when rescaling a stream recording, it’s crucial to optimize the encoding settings. Here are key considerations:
Bitrate and Resolution
A higher bitrate ensures higher quality, but also increases file size. For rescaling, it’s recommended to use a bitrate slightly higher than the original stream, e.g. 5-10%. The target resolution should be the desired rescaled resolution, e.g. 1920×1080 or 2560×1440.
Codec
H.264 and HEVC are the most widely used codecs for video encoding. For scaling, HEVC (H.265) offers better compression and quality compared to H.264 at the same bitrate. If compatibility is a concern, H.264 is still a viable option.
Keyframe Interval
Keyframes define the reference points for the video. Too short of an interval can increase file size, while too long of an interval can make rescaling less effective. A keyframe interval of 1-2 seconds is generally recommended.
Psychovisual Optimization
Psychovisual optimization analyzes the human visual system to distribute bitrate more efficiently. This can enhance perceived video quality while reducing file size. Using a psychovisual codec or encoding software that supports this technique is recommended.
Upscaling Parameters
When rescaling to a higher resolution, upscaling algorithms are used to fill in the missing pixels. Different algorithms offer varying levels of sharpness, smoothness, and artifact reduction. Experiment with different algorithms to find the one that best suits the content being rescaled.
Custom Resolutions and Bitrates
For advanced users, OBS allows for custom resolutions and bitrates. Custom resolutions enable you to stream at a specific resolution that is not listed in the presets. Bitrate settings determine the amount of data transferred per second, affecting the video quality and smoothness of your stream.
Custom Resolutions
To set a custom resolution:
- Open OBS and click “Settings” from the main menu.
- Go to the “Video” tab and click on “Custom” for the “Base Resolution” and “Output (Scaled) Resolution” fields.
- Enter the desired resolution values in pixels, e.g., 1920×1080 for a 1080p stream.
- Adjust other video settings as needed to match the custom resolution.
Bitrate Settings
To set custom bitrates:
- Go to the “Output” tab in OBS “Settings.”
- Under “Streaming,” adjust the “Bitrate” field to a specific value in kilobits per second (kbps).
- Higher bitrates generally provide better video quality, but require a stable internet connection to avoid buffering issues.
Bitrate Recommendations:
| Stream Resolution | Recommended Bitrate (kbps) |
|---|---|
| 360p | 600-1200 |
| 720p | 1500-2500 |
| 1080p | 3000-6000 |
Note: These recommendations are approximate and may vary depending on factors such as network conditions and desired video quality.

Avoiding Artifacts and Pixelation
1. Use Hardware Encoding
Hardware encoding uses your graphics card (GPU) to encode the video, which is much faster and more efficient than using your CPU. This will help to reduce artifacts and pixelation.
2. Set the Correct Output Resolution
The output resolution should be the same as the resolution of your stream. If the output resolution is too high, the video will be pixelated. If the output resolution is too low, the video will be blurry.
3. Use a High Bitrate
The bitrate is the amount of data that is sent per second. A higher bitrate will produce a higher quality video with fewer artifacts and pixelation.
4. Disable Scaling
Scaling is the process of resizing the video to fit the output resolution. If scaling is enabled, the video may be pixelated or blurry.
5. Use a Good Encoder
The encoder is the software that converts the video into a format that can be streamed. A good encoder will produce a high-quality video with fewer artifacts and pixelation.
6. Tweak the Encoder Settings
The encoder settings can be adjusted to improve the quality of the video. These settings may include the bitrate, the encoder preset, and the encoder profile.
7. Experiment with Different Encoding Software
There are many different encoding software programs available. Experiment with different programs to find the one that produces the best quality video for your needs.
8. Optimize Your Network Settings
If your network is not fast enough, it can cause artifacts and pixelation. Make sure that your network is fast enough to handle the bitrate of your stream. You can also try to reduce the bitrate of your stream if your network is not fast enough.
