WebM is known for its relatively smaller file sizes compared to other formats, but it's still possible to further optimize them. Re-encoding can significantly reduce the file size without sacrificing significant quality. This is crucial when sharing videos online, uploading them to social media, or storing them on devices with limited storage space.
WebM, while a versatile video format, comes in various encoding profiles and codecs. Sometimes, a WebM file created for one platform might not be ideal for another. For example, a video encoded for a high-end desktop might be too large or complex for a mobile device. By re-encoding the WebM file, you can optimize it for different devices or platforms. This involves adjusting the bitrate, resolution, and frame rate to tailor the video to the specific needs of the target audience and platform. This leads to faster loading times, smoother playback, and improved overall user experience.
