How to Compress Large Video Files

Sharing high-quality videos between colleagues and clients can be frustrating when video file sizes are too bulky. File sharing methods like email or corporate chat software have file size limits, keeping them from fitting into a message or taking a lengthy amount of time to download on the recipient’s end.

Compressing your video files cuts portions off the size needed by your file, meaning overall quality will take a hit. Depending on the original size of the file, a loss in quality may not be noticeable, but it depends on how much smaller you have to make it and whether or not the file can suffer quality reduction. While this may not be a huge issue for family and friends to share videos of birthdays or weddings, it could affect the success rate for filmmakers and post-production houses who rely on quality.

Here is how you can compress large video files, as well as the downsides and alternative solutions to sharing large video files.

How to Compress a Video File

Reduce Video Resolution

One of the most common ways that people compress files is by reducing video resolution. When a video has a high resolution, the quality of the image is sharper, making it a larger file. To make the file smaller, the video resolution needs to be lowered. An important thing to keep in mind is that lowering the resolution may compromise the overall quality of the image.

Compress into a .zip File

Another popular method for compressing a video file is zipping it. This ensures that the file size is reduced while still maintaining a majority of the quality. Unfortunately, zipping the file does not reduce its size significantly, so this method is typically useful when a file is just above email or chat limits.

The Downsides of Compressing Large Video Files

As mentioned, compressing video files not only causes a loss in video quality but can also reduce the quality of the audio. While it may not be imperceptible in some cases, it can be problematic in scenarios like color correction phases of post-production. It can also take additional processing time to compress files on top of multiple steps depending on which type of video playback software you’re using. Recipients may also have trouble opening a compressed file if they don’t have the right software to watch.
