How To Make Stream Recordings Rescale To 1920 Obs

Have you ever watched a stream recording and been disappointed by the quality? The video may be blurry, pixelated, or stretched out of proportion. This can be a frustrating experience, especially if you’re trying to enjoy a high-quality stream. The good news is that there’s a way to fix this problem: by rescaling the recording to 1920×1080. This will give you a much better viewing experience and make the recording look its best. In this article, we’ll show you how to rescale stream recordings to 1920×1080 using a variety of different methods.

There are a few different ways to rescale stream recordings to 1920×1080. One way is to use a video editing software program. Most video editing programs have a feature that allows you to change the resolution of a video. Simply import the recording into the program, select the “Resolution” option, and change the resolution to 1920×1080. Another way to rescale stream recordings is to use a command-line tool. Command-line tools are more technical than video editing programs, but they can be more powerful and efficient. To use a command-line tool to rescale a stream recording, you will need to open a command prompt and type in the following command:

ffmpeg -i input.mp4 -vf scale=1920:1080 output.mp4

This command will rescale the input video file (input.mp4) to 1920×1080 and save the output to a new file (output.mp4). You can also use the -crf option to control the quality of the output video. A lower CRF value will produce a higher quality video, but it will also take longer to encode. Once you have rescaled the recording, you can enjoy it in all its high-quality glory!

Configuring OBS Settings for Scaling

Step 1: Select Output Scaled Resolution

Configuring OBS for scaling involves modifying settings within the software to optimize the output resolution for streaming or recording. The first step in this process is to specify the scaled resolution for the output. This resolution determines the final size and quality of the streamed or recorded content.

To set the output scaled resolution, navigate to the “Output” tab in OBS and locate the “Output Scaled Resolution” field. Here, you can enter a custom resolution or choose from a predefined list of common resolutions. For streaming, a resolution of 1080p (1920×1080) is recommended for optimal quality and compatibility with most streaming platforms. For recording, a higher resolution such as 2K (2560×1440) or 4K (3840×2160) may be preferred for archival purposes or future scaling options.

Step 2: Configure the Base Resolution and Canvas Resolution

The next step is to configure the base resolution and canvas resolution. The base resolution determines the actual resolution at which the scene is rendered, while the canvas resolution specifies the size of the virtual canvas on which the scene is displayed. For optimal scaling, the base resolution should be set to the same value as the output scaled resolution. The canvas resolution, on the other hand, can be either the same as the output scaled resolution or a higher value. Using a higher canvas resolution allows for more flexibility in cropping and positioning elements within the scene.

Step 3: Adjust the Output Mode

Finally, select the appropriate output mode based on your scaling preferences. OBS offers two output modes: “Scaled Fit” and “Scaled Fill.” “Scaled Fit” maintains the aspect ratio of the scene and scales it to fit the output resolution without cropping or stretching. “Scaled Fill” stretches the scene to fill the entire output resolution, potentially cropping content. The choice of output mode depends on the desired visual outcome and the specific requirements of your streaming or recording setup.

For more detailed instructions on configuring OBS settings for scaling, refer to the following table:

Setting	Description	Recommendation
Output Scaled Resolution	Sets the final resolution of the streamed or recorded content	1080p (1920×1080) for streaming, 2K or 4K for recording
Base Resolution	Determines the actual resolution at which the scene is rendered	Same as Output Scaled Resolution
Canvas Resolution	Specifies the size of the virtual canvas on which the scene is displayed	Same as Output Scaled Resolution or higher
Output Mode	Defines how the scene is scaled to fit the output resolution	“Scaled Fit” or “Scaled Fill” based on desired visual outcome

Using Custom Resolution Plugins

If you want more control over your stream resolution, you can use custom resolution plugins. These plugins allow you to set any resolution you want, regardless of what your webcam or streaming software supports. This can be helpful if you want to stream at a higher resolution than your webcam can handle, or if you want to stream at a custom aspect ratio.

There are several different custom resolution plugins available, so you can choose the one that best suits your needs. Some of the most popular plugins include:

Plugin	Features
OBS-VirtualCam	Allows you to use any custom resolution with OBS Studio.
FFmpeg Plugin	A more advanced plugin that allows you to use custom resolutions and frame rates.
VLC Plugin	A simple plugin that allows you to use VLC Media Player as a custom resolution source.

To use a custom resolution plugin, you will need to download and install it. Once the plugin is installed, you can open OBS Studio and add the plugin as a source. You can then set the resolution you want to use in the plugin’s settings.

Using a custom resolution plugin can give you more control over your stream’s appearance. However, it is important to note that using a higher resolution than your webcam can handle can result in a decrease in video quality. Additionally, using a custom aspect ratio can cause problems with some streaming platforms.

Optimizing Encoder Parameters

The encoder parameters play a crucial role in determining the quality and scalability of your stream recordings. By fine-tuning these settings, you can ensure that your recordings are compatible with a wide range of displays and devices.

Video Encoder

The video encoder is responsible for compressing the video data and determining its overall quality. Choose a codec that offers a good balance of compression efficiency and visual quality, such as H.264 or H.265. Additionally, consider the following settings:

Bitrate: Adjust the bitrate to match the desired video quality and the available bandwidth.
Resolution: Set the resolution to 1920×1080 for optimal quality on most displays.
Keyframe Interval: A shorter keyframe interval results in better video quality, but it also increases the file size.

Audio Encoder

The audio encoder compresses the audio data and affects the overall sound quality of your recordings. Choose an appropriate codec and bitrate, and consider the following settings:

Codec: Select a lossless or lossy codec based on your desired sound quality.
Bitrate: Higher bitrates provide better audio quality, but they also increase the file size.
Sample Rate: The sample rate determines the audio fidelity and should be set to a value that matches your source material.

Additional Settings

In addition to the video and audio encoders, there are several other settings that can affect the scalability of your recordings:

Buffer Size: Adjust the buffer size to minimize latency and prevent buffering issues.
GOP Length: A shorter GOP length reduces latency but can increase file size.
Lookahead Delay: Increasing the lookahead delay allows for more efficient encoding but can also increase latency.

Here’s a table summarizing the key parameters to consider when optimizing encoder settings:

Parameter	Description
Video Codec	Determines the video quality and compression efficiency
Bitrate	Affects the video quality and file size
Resolution	Sets the pixel dimensions of the video
Keyframe Interval	Determines the frequency of keyframes in the video

Adjusting Bitrate and Resolution

To ensure that your stream recordings rescale to 1920×1080, you need to adjust both the bitrate and resolution settings.

Bitrate refers to the amount of data being transmitted per second. A higher bitrate will result in a better-quality video, but it will also require more bandwidth.

Resolution refers to the number of pixels in the video. A higher resolution will result in a sharper image, but it will also require more processing power.

Recommended Settings

For best results, we recommend using the following settings:

Setting	Value
Bitrate	6000 kbps
Resolution	1920×1080

These settings will provide you with a high-quality video that will rescale to 1920×1080 without any issues.
