How to Check MP4 Files

To check the compatibility of your MP4 files, you can use MediaInfo, a free software that provides detailed information about multimedia files.

1. Download and install MediaInfo
2. Set the options in MediaInfo to display information in TEXT format
   
3. Drag and drop the video file into the large, empty MediaInfo field to analyze it.
   

Interpreting MediaInfo Results

After analyzing the file, look for the "Format" field in the MediaInfo results. This will show you the codec used for the video.

For example, if you see "HEVC" in the Format field, this refers to H.265, which is not widely supported across all browsers. You can check this via https://caniuse.com/ and search for the format of your video.

Green indicates full support, while other colors may indicate partial or no support. Hover over browser entries for additional information.

Recommended Video Settings

To ensure the broadest compatibility with EFS and various browsers, use the following settings for your MP4 videos:

• Container: MP4
• Video Codec: H.264/AVC
• Audio Codec: MPEG-4 AAC-LC
• Profiles: Main / High
• Levels: 3 / 4
• Resolution: up to 1920x1080 (1280x720 if aimed towards mobile users)

Notes:

1. The longer a video and the higher the encoding setting, the larger the video file will be.
2. Always consider that especially on mobile connections, file size matters if bandwidth is limited.
