If you are uploading your course video on Dubata, and your uploads are taking too long due to its large file size, then follow these steps to properly reduce it — without losing much of your quality.

1. Download HandBrake

HandBrake is a great open-source program used to reducing large file sizes, without losing its quality. Simply go to google and type “HandBrake”, or simply click here to go to their website.

Once there, download the program for your type of operating system (should automatically detect it), save it to a desired location on your computer, and open it.

2. Select your file

Once you open HandBrake, it should immediately prompt you to choose a video file from your computer. If not, then select the Source button on the top-left of the HandBrake screen, then choose your file.

Note: You can only choose one (1) file at a time. However, if all of your video files are in the same folder, then you can just click “Open” (without selecting a file within that folder) and all the video files within that folder will load.

3. Choose these optimal settings.

Please note for this tutorial, we are using the Mac version of HandBrake. However, the same settings/presets still apply to Windows versions.

Speaking of presets, make sure the preset is on the Normal mode under Regular, located on the right side of your program (not pictured above). That’s the first thing you should take care of. It should already be the default option.

You can look at the screen and copy the settings we have here. Some of these we want to point out:

  1. Destination: This is where the reduced-size video file will end up. Select the “Browse” button on the right side to choose your desired destination. Note: If you have multiple videos, then you will have to do this one-by-one. Choose which video to use from selecting the “Title” section right above the “Destination” text.
  2. Web optimized: Have this checked.
  3. Format: Choose MP4 File for best quality.
  4. Quality: This is where the real file-reduction happens. Choose Constant Quality (should be the default setting). The RF should be default at 20. The higher the number, the worse the quality (and the lowest file size). The lower the number, the better the quality (the file size will be closer to the original). A great range is anywhere between 19 – 21. We chose RF 21, as we feel this is the best “bang for your buck” setting.

4. Encode the video

After adding your settings, press the Start button to encode your video. You will see the status on the bottom of your screen.

If you have multiple videos, or if you encode a video while another video is currently being encoded, then select the Add to Queue button right next to the Start button. You will see the number of videos encoding on the bottom-right of the screen.


After that, you should be good. Check your new video’s file size. Play it back to confirm quality is still good to your liking.

Once done, upload the course to Dubata.com.
