How to compress videos to smaller file sizes

How to compress videos to smaller file sizesVideos tend to have fairly large file sizes, which can be a problem. Not only does it make it more difficult to store them because of the sheer amount of space they consume, but it also means that transferring them is slow and takes a lot more time.

In some cases you may be unable to email your videos or transfer them using certain platforms due to file size limitations.

As you've probably heard, however, it is possible to compress videos and reduce their file size. That is true, but unfortunately it isn't as easy as hitting a button - at least not in most cases. To be more specific, there are several ways that you can compress videos, each with its own advantages and disadvantages.

Use newer codecs with better compression

One of the most effective ways to compress videos is to convert them to formats with newer codecs. Typically the better compression of newer codecs can help reduce the file size of your videos while keeping them at the same quality.

For example if you convert a video from a H.264 codec to H.265, you could reduce its file size by about 50%. The quality of the video will be the same, so it's really a win-win situation.

The only drawback of this method is that if your video is already encoded using a new codec with good compression, it may not be an option that is available to you.

Reduce the bitrate of the video

Another option to reduce the file size of videos is to reduce its bitrate. Simply put, the bitrate of the video is the amount of data that it uses per second. The total file size is literally the bitrate multiplied by the video's duration.

Unfortunately this method of compressing videos will affect their quality, though the degree to which it does will depend on how much you reduce the bitrate of the video. The optimum bitrate for videos will vary based on their resolution, frame rate, and format - but as you start to reduce it below that, you'll notice artefacts (distortion) beginning to appear.

In short, if you intend to compress videos by reducing their bitrate, you will need to carefully find a compromise that is able to provide a smaller file size while still retaining an acceptable quality level.

If you want, you can downscale the video to a lower resolution to keep the bitrate within optimum levels for that resolution.

Trim out unnecessary video parts

Technically this isn't a way to compress your videos, but it is an effective method to reduce its file size. If you have videos where only particular parts are of interest to you, it is possible to trim out all the rest and end up with a shorter, smaller video clip.

Needless to say this method is very situational, but it is an option that you should consider. The benefit of trimming out unnecessary video parts is that you don't end up reducing the quality of your video in any way.

Final words

It is worth noting that there are other ways that you can compress and reduce the file size of videos - such as reducing the audio bitrate. Generally, however, the audio bitrate of videos is quite low, and reducing it won't have that big an impact.

Instead your best bet is to use one of the methods described above, and Movavi Video Converter can provide what you need to do so. It is an easy-to-use video converter that will allow you to convert your videos to formats with better compression, compress them by reducing the bitrate, or even trim out unnecessary parts of your video.

On top of that there are lots of other features in Movavi Video Converter that you can use to convert audio and image files, create animated GIFs, extract audio tracks from videos, enhance the quality of videos, and more. Simply put not only will you be able to use it as a video compressor, but it will also come in handy in lots of other ways too.
