How do I compress a video without losing quality using ffmpeg?

Run ffmpeg -formats or ffmpeg -codecs for a list of all of the available formats and codecs. If you don’t have to target a specific codec for the final output, you can achieve better compression ratios with minimal quality loss using a state of the art codec like H. 264.

How does Ffmpeg reduce video size?

To use it, replace the libx264 codec with libx265, and push the compression lever further by increasing the CRF value — add, say, 4 or 6, since a reasonable range for H. 265 may be 24 to 30. Note that lower CRF values correspond to higher bitrates, and hence produce higher quality videos.

Does Ffmpeg improve video quality?

With this simple command, you can change the video’s resolution with FFmpeg. And, after FFmpeg changes the resolution of the video, it will re-encode it at that resolution. For example, you could tell FFmpeg to encode it using crf=18 for pretty high-quality H. 264/AVC encoding, or choose something else!

To scale down a high-resolution source video to something more reasonable for Web ( qHD for cellular, HD for broadband ), the -filter:v argument is used:

Which is the best codec to compress video?

When using ffmpeg to compress a video, I recommend using the libx264 codec, from experience it has given me excellent quality for small video sizes. I have noticed that different versions of ffmpeg will produce different output file sizes, so your mileage may vary.
