Which Encoder Is Best for Compressing Video?

We use two popular video encoding methods that are supported by most modern devices and browsers: H.264 and H.265. Out of these two encoding methods, H.265 yields better compression, especially at higher resolutions such as 1080p or 4k.

Advanced Methods of Video Compression

There are two main methods to compress a video. You can either optimize the bitrate or resize the video to a smaller size. We provide 4 settings related to both methods. Here’s an explanation:

1. By Video Quality

CRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. To do that, it uses different compression levels on different frames. For H264 encoder, possible CRF values range from 0 to 51. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). The default is set at 23.

Preset: Presets refers to the video compression speed. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level. If you prefer lower file size over encoding time, choose a slower preset.

2. As a Percentage of the Original Size (Default)

This method allows you to set a target file size for your video as a percentage of the original size. For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less.

The pros of this method is, you can achieve a certain target size. The downside is you don’t know how the target size will affect video quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. Increase the target size if you need better quality.

This is the default video compression method used.

3. Set Max Bitrate

This method allows you to set the max bitrate for given video quality. The quality is set by CRF (constant rate factor). Select this method if you are using the video in a streaming application where you want to control the streaming bandwidth rate. To choose this option, select “By Max Bitrate” from the “Video Compress” dropdown.

4: Make Video Size Smaller (Re-Size)

Choosing a smaller video resolution (dimensions) can also save file size. For example, if you have a 4K (4320p) video but your target device is 1080p, you can downsize the video to fit 1080p and save file size. To choose this option, choose “Re-size video” from “Advanced Settings” above.

How to play compressed video?

Codecs we use for compression are supported by all major browsers and devices. So you should not have any playback issues. If any issues, try opening the video with the free VLC player (Windows, Mac, Linux, and Mobile versions available). Allowed file types are: mp4, m4v, mkv, avi, wmv, f4v, f4p, mov, qt, vob, mpeg, m1v, mpv, 3gp, 3g2, rmvb, mts, m2ts, xvid, flv, rm, divx, asf, webm, wtv, dvr-ms, ogv, swf, mpg, 3gpp

First of all, the most important option is “Desired Video Size”. After software open a source video, it will read and show key video information, such as: File Size, Bitrate, Duration, Video Format, Video Bitrate, Audio Format, Audio Bitrate and Video Dimension (Width / Height), then software will calculate an estimated output video size, that is “Desired Video Size”. This desired video size is approximate value, resulting file may be smaller or larger than this size, you can change this value as you need. (Bitrate information is displayed as KB/S, KB/S = kiloBits/second).

The generated video format is MP4 container format with H.264 video codec and AAC audio codec. The encoding video quality is based output file size, output file size is more bigger and resulting video quality is more higher and more clearer.
