How To Reduce Video File Sizes Without Affecting Quality


Reducing the file size of videos is sometimes a little bit like walking a tightrope – on one hand you want the video file size to shrink, but on the other hand you don’t want its quality to be affected.

Is that even possible without an amazingly deep knowledge of compression? In some ways – yes.

The first thing that you should look at is the specifications of the device that you’re using, and that of the video. In some cases (particularly with mobile devices) the video settings exceed what the device is capable of displaying. For example, you may have a 1080p Full HD video sitting in the storage of a device that is only capable of playing 720p resolution at most.

In that scenario, by reducing the resolution to 720p you won’t see a visible change in its quality but its file size will be reduced.

Matching the video settings to the device specifications in this fashion can be an extremely effective way of reducing video file sizes and you can do the same for your frame rate as well as digital audio.

Apart from that however, there’s one other option to reduce video file sizes: Trim the video length. That may sound a little bit radical, but assuming you are only really interested in certain bits of the video it might be feasible to simply cut out all the other parts and keep just the bits that you’re interested in.

Matter of fact if this applies to multiple different videos then you may even want to cut out the parts that you want from each of them and compile them into a ‘highlights’ reel of sorts.

Needless to say this solution is highly situational but it is worth bearing in mind. After all, if storage space is really tight then it might be better to keep the important parts of the video rather than none of it.

Don’t worry if you’re not quite sure how to tweak or optimize the video settings, or even trim out unwanted video. With the Movavi Screen Capture Studio for Mac you can accomplish both rather easily, and even use it to record screen and audio on Mac. In fact, you could even use the presets in the software to automatically optimize it based on a specific device or platform – which might be the easiest option yet.
