How to Compress and Reduce the Size of Video Files


Understanding video compression can be difficult, but the good news is that you don’t need to delve all that deep into it to reduce the size of your video files. In fact, all you really need to know is that when videos are encoded they use video codecs that determine the type of compression that is used.

Almost all the videos that you are likely to encounter are compressed – unless you’re handling raw and uncompressed videos. If you want to reduce the file size of videos further however, there are several options that you could consider:

Using Video Codecs With Better Compression Rates

Although your video is probably already compressed and encoded using a particular codec – it may be possible to compress and reduce its file size further by using a different codec that has better compression rates. As a rule newer codecs often provide improved compression rates, and are able to reduce the file size of videos significantly while maintaining their quality.

A good example of this is comparing the H.264 codec with H.265. Of the two, H.265 is newer, and is able to reduce the file size of H.264 videos by up to 50% due to its improved compression rates.

However, despite the fact that this is a good way to reduce the file size of videos, care should be taken as newer codecs often aren’t as widely-supported. In short, you will need to check that the device or platform you are using supports the codec that you want to use.

Reducing the Video Bitrate

If using a codec with better compression rates isn’t an option, or it doesn’t sufficiently reduce the file size of your videos – you can reduce the video bitrate instead. Because the bitrate is literally the amount of data that the video uses each second, reducing it will directly reduce the file size of the video.

That being said if you do reduce the video bitrate the quality of your video will also be affected. As the bitrate gets lower, various types of compression artifacts are more likely to appear and eventually it may even become unwatchable.

Due to that risk, it is best to reduce the video bitrate gradually while making sure the video quality is still satisfactory until you arrive at an acceptable balance.


As you can see, you don’t need a technical understanding of video compression to compress and reduce the file size of your videos. In fact, the only thing that you do need is a video converter, and for example you could use Movavi Video Converter to convert the codec by following the steps at www.movavi.com/support/how-to/how-to-convert-mov-to-mpeg.html or reduce the bitrate.

If possible, try to keep a copy of the original video, regardless of which method you use to compress it. It will help you to avoid quality deterioration that can be caused by transcoding the same video over and over, and will ensure you have a copy in the original quality that you can fall back on.
