For users who need to compress a video on mac for email, reducing the file size can make large videos much easier to send while keeping reasonable quality. Shutter Encoder provides bitrate and file-size controls that make it possible to create a smaller copy for sharing.
How to use:
- Open the program, click Browse, and select the video you want to compress. The selected file will appear in the file list.
- Step 2: Open the Choose function menu and select a suitable compression codec such as H.264.
- In Bitrates adjustment, enter a lower value in VBR Video bitrate. You can also use the File size field when you want to target a specific output size.
- Adjust Audio bitrate if additional size reduction is needed. Avoid setting it unnecessarily high when the video mainly contains speech.
- Check the output destination at the bottom of the window. Select Change if you want to save the compressed file somewhere else.
- Click Start function and wait for encoding to finish. Check the resulting file size and play the video before attaching it to your email.
Its advantages include flexible bitrate controls, format support, and useful output settings, making it practical when you want to compress a video on mac for email. The main disadvantage is that some compression settings may take a little time for new users to understand.
Notes:
- Keep a copy of the original video before compression.
- Lower bitrates create smaller files but can reduce image quality.
- Check your email provider's attachment-size limit before choosing a target file size.
- Preview the compressed video before sending it.
