How Do I Resize Files?
Sometimes files are saved way larger than we’d like and when uploaded to view online, can create pages that load slowly for users. Below are some recommendations on how to resize some common file types.
You can reduce the file size by choosing one of the following methods. It's important to double check the quality of the video after reducing the size to make sure the quality has not been degraded too much.
You can check out Wistia’s guidelines for exporting and Handbrake’s for resizing.
Reduce the dimensions
- 1920 x 1080 is HD
- 1280 x 720 is smaller but still HD (great if you need to reduce the size!)
- 640 x 480 is Standard Definition
Reduce the quality or bitrate (the lower, the smaller file size)
- Around 20 mbps is the typical bitrate for an HD Blu-ray Video
- Around 6 mbps is usually Standard-Definition DVD
- Around 2 mbps is High-Quality Web Video
- Video for phones is typically given in the kilobits (kbps)
