What Is F4V
F4V (Flash Video) is a digital video container format based on the MPEG-4 standard. It is primarily developed by Adobe Systems. F4V uses the H.264 video codec and the HE-AAC audio codec. Besides, it can be played on Adobe Flash Player or web browser plug-ins. Actually, F4V is an outdated format with limited applicability.
What Is WebM
WebM is a royalty-free video file format sponsored by Google. It provides high-quality video with a small file size and is ideal for HTML5. WebM adopts VP8, VP9, and AV1 video codecs and Vorbis and Opus audio codecs. Also, it is natively compatible with Google, Firefox, Edge, and more web browsers.
F4V vs WebM: Core Differences
What are the differences between F4V and WebM? I will list the comparisons of them in terms of compatibility and file size.
#1. Compatibility
F4V has limited compatibility. It doesn’t support playback on most browsers, streaming platforms, and mobile devices. On the other hand, WebM has wide compatibility. Designed for HTML5, it can be directly embedded in webpages for playback, making it more popular.
#2. File Size
F4V uses H.264 video codec and AAC audio codec, which offers a small file size without losing much quality. WebM uses more optimized codecs, including AV1 and VP9, which provide better compression efficiency. So, it doesn’t take up much space.
Why Convert Between F4V and WebM
F4V is outdated today, which means many web browsers no longer support it. WebM is more compatible with webpages and can be played on most modern devices without plugins. Therefore, converting F4V to WebM increases the video accessibility.
On the contrary, converting WebM to F4V is for compatibility with older systems, players, and software that only support F4V.
