Video Compression

Resizing videos is a bit more involved than resizing images. You will need a tool to resize your video files. Here are a couple of simple options we recommend, but we also suggest conducting research to find the best tool for your needs:

Below, we'll provide instructions for each option.


VideoSmaller is a free, online tool specifically designed to reduce the file size of videos. To use it:

  1. Upload your video file.
  2. Select the desired width you'd like to scale to. For example, if you're optimizing for a 1920 x 1080 pixel screen, choose 1920.
  3. To maintain quality, you can select "use low compression level" (you can experiment with and without this option to see its effect on your video).
  4. Optionally, you can choose to remove the audio from your file if you won't be displaying it with sound.
  5. After you upload the video, you'll be provided with a link to download the optimized file.

Handbrake (MacOS / Windows)

Handbrake is a powerful open-source tool for video transcoding. It offers features such as changing video size, resolution, and audio encoding. To optimize your videos using Handbrake:

  1. Launch the Handbrake app and choose your video file.
  2. In the various tabs and options available, focus on the "Video," "Dimensions," and "Audio" settings.
  3. In the "Dimensions" tab, select the resolution that best matches your screen (e.g., 1080p or 4K).

  1. In the "Video" tab, choose the h.264 codec, as this is what TelemetryTV uses and it will improve upload time.

  1. In the "Audio" tab, you can delete audio support for a video by setting the recognized track to "none" in the tracks field.

  1. Verify the audio settings in the selection

Once you've completed these steps, click the start button to re-encode the video. The same configuration applies for other platforms, as Handbrake is cross platform tool.
