The Truth of Video File Size

There is a general consensus that large video files can be hard to work with or view on certain devices. Learning how to compress a video file while maintaining its quality and dimensions becomes a requisite nowadays. Before we get started, it's necessary to understand what are the factors that affect video file size. Technically video file size depends on many variables.

We have to mention that resolution is the most important one. Almost every compressor compress files by changing the parameter of resolution. The resolution of a video determines the size in height and width that the video will be created in. Resolution is defined by the number of horizontal lines the video has from top to bottom. Larger resolution videos will dramatically increase file size.

The following factors are bitrate and duration. Multiply them together and you get the size. Now bitrate will affect video quality, so you must find the balance for your application.

Frame rate is the one we don't want to miss. It does not affect video quality directly. It decides the fluidity, which in turn affects visual effects. Guess that a footage stuttering badly is by no means a HQ video. Frame rate being too high or too low will cause "unnatural " problem. So proper frame rate is important to make your video look realistic, just as how we see motions in real life.

Technically, if you want to compress a video size, I suggest you choose H.264 Baseline Profile. This format will compress your video files without losing too much quality.

As you'll see, there are plenty of other options for compression. Feel free to try some of them out to see how small they get your video file. Meanwhile, changing the Resolution and Aspect ratio is the way to adjust the size of the video.

However, you should know that Shotcut won't automatically adjust the corresponding option for you. What does that mean? If you change the vertical resolution, you'll need to calculate the corresponding horizontal resolution to make sure you don’t get a pinched video.

Choosing a lower-quality output will automatically adjust the resolution for you. Say, if you select HDV (hdv_720_25p), the resolution will decrease if your video was originally in 1080p. But if you want to go smaller than the preset resolution, you'll need to calculate the correct dimensions yourself.

You can also use the export window to customize exporting options to get exactly the type of file you want. This is best left to expert users, though you can certainly play around with it to see what happens.

System: Mac ONLY


  • very friendly for Mac users

To compress video files on QuickTime, open the app from your Applications folder and click File then click Open File to load your video.

To begin compressing your video files, click File and then choose Export As. Unfortunately, QuickTime doesn’t give you that much options. You'll see 4k (if applicable), 1080p, 720p, and 480p options.

Select 480p (assuming you recorded in720p) and export your file. It should be smaller than when you started.
