HandBrake Video Compression Guide¶

Follow these steps to efficiently compress your project videos while maintaining excellent quality.

1. Select the Source¶

• Open Source: Click this button in the top left corner to import the video you wish to compress.
• Verification: Once the file is loaded, verify the information displayed under Source (e.g., 848x480, 30 FPS).

2. Choose the Preset¶

• Preset: Avoid using resolutions higher than your source (e.g., selecting "Fast 1080p30" for a 480p video), as this increases the file size unnecessarily.
• Tip: Click the Presets dropdown menu (top right) and choose a preset in the General category, such as Very Fast 480p30 or Fast 480p30, for better alignment with your source.

3. Adjust Settings¶

Summary Tab (Format)¶

• Leave the format set to MP4 (universal).
• Check Web Optimized if you plan to share these videos on professional platforms or social media.

Video Tab¶

• Video Codec: The H.264 (x264) setting is ideal.
• Constant Quality (RF): This is the most important setting. A value between 20 and 23 offers the best compromise between file size and visual quality.

Audio Tab¶

• Verify that the codec is set to AAC or MP3. For a technical demonstration, a stereo bitrate of 128 kbps is sufficient.

4. Destination and Start¶

• Save As: Click the Browse button at the bottom of the window to choose the destination folder and name your final file.
• Start Encoding: Once the settings are configured, click the green Start Encode button located in the top toolbar.
