-
Open the video file you want to reduce the size of. You can either drag and drop the video file to the box on the right or click File in the menu to the left. Then select the file you want to open and click Open .
- If you don't see this screen, click Open source at the top of Handbrake.
-
Choose a filename for the output video. It's a good idea to set a unique name for any video you export. Type the file name you want to export the video as next to "Save as" at the bottom of the Handbrake.
- To select a new location to save the video to, click Browse and navigate to the location you want to save the video to.
-
Set where you want to save the output file to. To do this, type a name for the video file next to "Filename" and select the folder you want to save it to. Then click Open
-
Ensure "MP4" is selected next to "Format". The drop-down menu is next to "Format" on the Summary page allows you to select the video format. MP4 is the most common video format. It allows for maximum compression and produces smaller video file sizes without reducing quality. If you don't see this option, click the Summary tab in the middle of Handbrake.
- If the original video file is in a different format besides "MP4" (i.g. .MOV, or .WMV), simply converting it to an MP4 file may do a lot to reduce the file size without having to reduce the picture quality. [1] X Research source
-
Click the Dimensions tab. This tab allows you to adjust the image size.
-
Type a smaller number into the "Height" and "Width" field. This will lower the resolution of your video, which can drastically lower the file size. For example, changing the width value from 1920 to 1280, and the height value from 1080 to 720 will change the video from 1080p to 720p, resulting in a much smaller file. This will reduce the picture quality. You'll want to keep the picture size proportional to avoid cropping or stretching. Some common video sizes include the following:
- 2160p: 3840w x 2160h (extremely large, 4K ultra HD).
- 1440p: 2560w x 1440h (larger).
- 1080p: 1920w x 1080h (large, standard HD).
- 720p: 1280w x 720h (medium).
- 480p: 854w x 480h (small).
- 360p: 640w x 360h (smaller).
- 240p: 426w x 240h (smallest).
-
Click the Video tab. This tab allows you to adjust the video quality, codec, and frame rate settings.
-
Click and drag the Constant Quality slider to the left. Increasing the value will lower the quality, which will result in a smaller file size.
- 20 is considered DVD quality. If you're going to be playing the video on a small screen, you can probably go as high as 30. For larger screens, stick to 22-25 is good constant quality.
-
Use the drop-down menu next to "Framerate" to select the frame rate. Framerate is the number of frames-per-second a video uses. A lower framerate can reduce the video size, but result in choppier motion. Anything above 20 frames-per-second (FPS), should look okay.
-
Click the Preview button. You'll see this at the top of the Handbrake window. This displays a still image from the video so you can check the image quality.
-
Check the Live Preview box. It's at the bottom of the Preview window. This plays a few seconds of the video at the quality you selected. If it looks okay to you, continue on to the next step. If the video quality is subpar, go back and raise the video resolution, framerate, and/or Constant Quality by just a tad.
-
Click the Start Encoding or Start button. It's the green play button at the top of Handbrake. This will start encoding a new video file with the specifications you set. The time this takes will vary greatly depending on the size of the video, your encoding settings, and your computer's processing power.
