Make sure to download and install HandBrake from the official website
Open the program, it will ask you to select your original file
Choose your preset
For online platforms such as custom websites or Notion, I recommend the "Web → Discord" presets. Choose the specific one for you depending on the length of the video. The options will change according to the preset.
Select the destination file
Add more files to the queue, if needed
At this point, if you have more files you want to convert, you can click on the "Add to Queue" button, and keep on opening files, assigning a preset, and adding to queue.
Start
Click on the green start button, the program will start working and notify you when it's done.
Profit!
Our demonstration video created from After Effects went from 29.2 MB to 746 KB without any decrease in resolution, or perceptly lowered quality. It will now load much faster from Notion.
