3 Tips to Compress Videos Effectively for Mobile Devices

Abhigyan Singh 30th Oct 2018

Mobile devices generally have limited storage capacity, which can be an issue when you start to store videos on them. Because the file size of videos can be quite large, you could fill up the storage that is available really quickly.

That is why it is a good idea to compress videos and reduce their file size before storing them on mobile devices. In some cases you may even be able to significantly reduce the video file size to a fraction of what it used to be.

To compress videos effectively for mobile devices however, there are a few tips that you need to follow:

  • Use codecs with high compression rates and hardware support

One of the best ways to compress videos and reduce their file size is to transcode them to a codec with better compression rates. If you do so the quality of the video should remain the same, but the file size will be smaller.

While newer codecs generally have much better compression rates, you should make sure they also have hardware support on your mobile device. If they do not they’ll consume a lot of processing power and battery life – which isn’t ideal.

For example transcoding videos from H.264 to H.265 could reduce the file size by up to 50%, but H.265 does not have hardware support on most Android devices.

  • Carefully and gradually reduce the bitrate

The other main option that you can use to compress videos is to reduce the video bitrate. That should be done carefully and gradually, as the more you reduce it the greater the chances that compression artifacts will appear.

Finding a balance between the video bitrate and quality is key if you go down this route.

  • Extract shorter clips for mobile devices

While technically this won’t ‘compress’ the original video, it is a good way to reduce its file size for mobile devices – especially if you’re only interested in a certain part of the video. By extracting shorter clips you could significantly reduce the size of the video that you eventually store on your mobile device.

The exact reduction will vary depending on the length of the clip that you extract. If possible you should use this method alongside the other methods described above, to truly minimize the video file size.

To start compressing your videos using any of the methods described above, you need a way to transcode, trim, and adjust the bitrate of your videos. For example you could use Movavi Video Converter for Mac to perform whichever method you prefer.

At the end of the day your goal should be to compress your video using the best possible video codec, and then reduce its bitrate or extract clips from it if necessary. If you still run into storage issues after that, you may want to look into other options – such as storing only the videos that you watch frequently on your mobile device and moving the others to the cloud instead.
