This topic can be confusing, so it's important to learn the difference. In this article, we will learn about codecs like VP9 and H265, and how we can optimize video using ffmpeg tool. Using video for animation with proper optimization is always better than GIF and sometimes outperforms native implementations. Modern video codecs can deliver excellent quality while preserving a very reasonable size. Unfortunately, the same can't be said about videos. When it comes to images, almost every framework, headless CMS, or CDN offers built-in optimization options. Frameworks compete by optimizing network requests, images, and code to achieve a blazing-fast loading experience. The option does not mean same quality.Modern web development every year applies new standards for performance. Sameq tells FFmpeg to use the same quantization parameters when converting video with the same codec that was used for the input. Basically, FFmpeg just reads and writes the container and doesn't change the codecs. Here's an example that changes the container from AVI to MP4, if the video bitstream is valid for MP4 as well: ffmpeg -i input.avi -c:v copy output.mp4Īgain: FFmpeg will copy anything that it finds. This, in essence, gives you the same quality, as nothing will be changed in the video bitstream. ![]() For example, your AVI video has an XviD video bitstream, and you can copy it to an MP4 container, without re-encoding the video. c:v copy tells FFmpeg to copy the bitstream of the video to the output. The accepted answer is incorrect-or at least doesn't really explain what the options actually do. ![]()
