Video encoder quality vs video file size efficiency, ranked worst to best: VP8, AMD/Intel QSV/NVIDIA NVENC hardware encoder, x264, x265, and VP9. Handbrake shows good video compression efficiency, however, it becomes complicated for beginners to figure out its video and audio setting adjustment.

To get better video compression performance on Windows 10, make sure you update to the latest version of Handbrake - 1.4.0 released on July 18, 2021.

Freemake video compressor software fully supports 4K, Full HD 1080p, and HD 720p files from HD cameras, camcorders, and Blu-ray. But without hardware acceleration, 4K/HD videos compression can be slow on Windows 10 or other lower end devices, especially if you want to compress videos to advanced codecs like HEVC and AV1. Slow video compression speed is a big cons. Some users reported that the free video compression software for Windows 10 failed to work on WIndows 10.

4. FFmpeg

Reasons to Download

  • Free and open source
  • Video compression efficiency can be high

Reasons to Avoid

  • Requires deep learning curve for beginners

Overview: FFmpeg is the best go-to free compressor software for WIndows 10 that can compress video size from GBs to MBs without losing much quality. FFmpeg uses command lines to do the video, audio, and other multimedia settings, such as bit rate, frame rate, container format, codec format, to name a few. The Constant Rate factor (CRF) is the quality setting by default for x264 and x265 encoding. The higher the value, the higher the compression, and more quality loss. FFmpeg can compress a video file from 1 GB to 30 MB.

Below are commands with ffmpeg to compress MP4 video file on Windows 10 and final video size results.

  1. ffmpeg -i input.mp4 -vcodec h264 -acodec mp2 out.mp4, 2 GB to 380 Mb, great quality
  2. ffmpeg -i input.mp4 -s 1280x720 -acodec copy -y output.mp4, 1 Gb to 25 MB, acceptable quality
  3. ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k -acodec mp3 output.mp4, 1 Gb to 15 Mb, very poor quality

The video compression command line requires a deep learning curve for non-tech savvy users. The free video compression software for Windows 10 may output an even larger file size if you enter an improper command line for codecs, bitrate, container, and fps. Many users are confused about its CRF value, codec, fps, and other settings. Setting the -maxrate and -bufsize to lower down the bit rate and the result is not satisfying. The range of the CRF value is from 0 to 51, 0 is lossless and 51 is the worst quality but the smallest video file size. A lower value of CRF means higher quality but larger file size. Increasing the CRF value +6 result in half of the video file size on Windows 10.

Key Features

  • Compress video size from GB to MB without quality loss by dividing target size (in bits) by the video length (in seconds) or setting the video to Constant Rate Factor (CRF) which will lower the average bit rate but with better quality.
  • Based on libavcodec, FFmpeg can compress videos to MP4, AV1, HEVC H.265, H.264, VP9, WMV, most other codecs.
  • Easily modify the bit rate, video screen size, change profile to baseline, etc.
