As you’re probably aware video files can take up a lot of storage space, and their large file sizes can make transferring or sending them to others difficult as well. That is why it helps to know how to compress the file size of videos, so that they can be managed and stored more easily.
If you would like to compress your videos, there are several ways that you can do so. Each method is different in its own way, and you should carefully choose the one that is best for your video.
Using Codecs with Better Compression
Every video format has a codec that determines how that video is compressed – and newer codecs tend to have more efficient compression rates. By using a codec that has better compression, you will be able to reduce the file size of your videos without compromising its quality.
In order to change the codec of your videos you’ll need a video converter for Mac or Windows – preferably one that supports newer codecs. On top of that you’ll need to determine whether or not it is an option in the first place, and if your video already uses a new codec with good compression then this method won’t work.
Another factor to keep in mind is that newer codecs may not be compatible with some devices or platforms – and you’ll have to check on that as well.
Reducing the Video Bitrate
Arguably the most effective way to compress videos is to reduce the video bitrate – which is literally the amount of data that it uses each second. By lowering the bitrate you’ll be able to directly reduce the file size of the video, but at the same time its quality will be affected.
If the video bitrate is too low the quality of the video could become poor and various artifacts will start to appear. That is why you will need to find a balance that is acceptable between the quality of the video and its file size when you reduce the bitrate.
Lower the Video Resolution
To put it simply videos with lower resolution require a lower bitrate and as such have smaller file sizes. However at the same time lowering the resolution will directly affect the quality of the video – which is why this method isn’t used all that often.
Still if the resolution of your video file is higher than the resolution of the display that you’re using then lowering it won’t noticeably affect the quality of your video. In other words you could ‘compress’ the file size without any noticeable drop in the video quality, which is the one situation in which this method is best.
Now that you know what your options are in terms of compressing video files you should be able to identify the method that you want to use. At the end of the day there is no ‘one size fits all’ method of compressing videos that is best, and it will vary on a case by case basis.
