How to Compress Videos

Edited by Pat Bitton

August 29, 2019

Nobody wants to delete a favorite movie just because of its file size. When a video file takes up too much space on your hard drive or doesn’t fit on the memory card for your portable device, you’ll need to compress it. And you’ll want that compression to be lossless, i.e., without any significant loss of quality.

If you like watching films on your multimedia player, smartphone or tablet, you’ll definitely want to find the best way for downsizing large video files because data storage is usually quite limited. Plus, to transfer any video clip to a specific portable device, you may also need to convert it to a video format supported by that device.

In addition to mobile device usage, you also need to compress movies when you’re preparing them for web upload since many online video sharing sites limit the video size and format of footage you upload.

Here’s a short summary of some circumstances in which you might consider video compression.

Videos take up too much space

Even if your storage is really huge, there will come a day when you won’t be able to download one more movie without first doing some cleanup. Store all your archives and favorite videos by compressing them, and there will be enough space for new ones.

Videos upload too slowly

If you want to send a video to your friend via email or transfer a movie to a flash drive, you might encounter a problem: large videos take too much time to upload. Speed up the process by compressing the files. Time is money!

It costs too much to store videos in the cloud

Cloud services ask to pay for additional storage. If you have too many files in the cloud, you’ll need to buy more space – or compress the files. In the latter case, you can keep everything you need and will still be able to upload more files.

The tutorial below explains how to compress video. Before we start, download and install Movavi Video Converter – the perfect video compression software for compressing digital video files or DVDs. You can also use the software to convert videos to a different format – MP4, MOV, WMV, AVI, MPEG, and many others – depending on your requirements.

Here, you can see some examples of video compression with the help of Movavi software. Of course, these numbers are just the average – actual results depend on the compression options you choose when working with the program.

With Movavi Video Converter, you won’t need a degree in video engineering to convert even HD movies for playback on your mobile device or compress videos for web upload. The program provides a wide range of conversion presets for most mobile devices and websites.

To reduce the file size of your videos with the Movavi video compressor, follow the simple steps below.

Add a Video File

Click the Add Media button and then Add Video in the upper left corner of the program interface. Choose the video you want to convert from the Open File dialog box and click Open.

Choose the Format or Device Preset

Choose the desired video format or target mobile device from the ribbon of presets. You can also use the search function to quickly find the format or device you need. Alternatively, if you connect your device to the computer and click the Cell Phone icon to the right of the search bar, the program will detect your device automatically and suggest the appropriate preset.

Define the Compression Rate

Return to the source file list and click on the file size in the output information. This will open a new dialog box. Move the File size slider to the desired output file size and bitrate. You can click the Convert Sample button to check how a small segment of the file will look like after conversion.

Compress the Video

Choose the output folder for the compressed videos by clicking the Folder icon at the bottom of the interface and selecting the desired destination. By default, the output video will be saved in the Movavi Library folder.

Press the Convert button to start the compression process. After the operation is complete, the output folder with the converted video will open automatically.
