Compress a Video to Reduce the File Size (Desktop Computer)

Video files are, by nature, larger than most other file types that you would upload to CWPro. This larger file size equates to longer upload times, which is what allow issues to arrise during the upload process (internet connection issues, bandwidth issues, etc.). To reduce the time it takes for a video file to upload to the internet we recommend that you reduce its size by compressing it first. This help page will show you how to compress your video file into a smaller and more manageable format. Since CWPro does not provide video compression tools we recommend Handbrake™, as it is free to download, easy to use and is available for both Mac and Windows users.

NOTE: These instructions are not specific to CWPro. The same steps can be used to compress a video file before uploading it to YouTube, Google Video or other Internet websites.

If you would also like to edit your video to rearrange or remove specific clips and shorten the overall length of the video, please visit our Video Editing help page before compressing your video.
