Bonus Tip: What Makes A Video File Size Larger/Smaller

Basically, the size of video file has impacted by three elements: resolution, bitrate, and encoding.

Resolution is what we often said the number of pixels. It is presented as a width and height measurement such as 1920 × 1080.

Now, you may be wondering which resolution should you use. Actually, it’s based on which device you may use to watch your video. For example, if you need to watch it on a large screen, such as TV, you can stream in 1440p or 1080p.

We know that many of you pursue a higher-definition (4K) watching experience. But if the display of the screen is not good enough to reach 4K or 1080p, then a 4K-resolution video is useless. Therefore, the most suitable resolution for a device is the best.

The next one involved is how much information is transmitted every second. That's what we called bitrate. Here are some recommended bitrates for different frame rates and sizes.

    Note Although variable bitrate allows you to go above or below the target bitrate, it will give you less control on video file size, so you may wanna avoid to select this option.

What the last but not the least is encoding. we highly recommend you use H.264 encoding with MP4 encoder. In this situation, this is an effective and efficient way to compress your video.
