How to lower bitrate for videos and recordings

There are cases where the pre-recorded streams could not reach certain platforms, and the cause of the issue is usually the video's too high bitrate.

To avoid this, you can use an application called HandBrake to lower the bitrate and FPS on your videos/recordings.

  1. Download HandBrake from its website. The app is available for Max, Linux, and Windows.

  2. After finishing installation, add your video

  3. Go to the Video tab to see the bitrate settings. We suggest setting it between 1500 and 2500 to accommodate different social platforms. Don’t forget to convert your file into x264, as x265 support is limited across most websites.

4. Go to the Audio tab to change the audio bitrate settings.

5. Click Start Encode, then re-upload your video to Castr.
