MP4 to SWF

MP3 has always been the popular audio format and for several good reasons, its video format counterpart, MP4, has been the same.

It’s understandable as both formats are versatile and compatible with virtually all platforms. They are among the few formats that can be accessed on Windows, Mac, and smartphone platforms without a special video player.

That said, there is interest in converting MP4 to SWF due to the benefits the latter has for website purposes.

SWF isn’t the first format that video editors consider. However, it is a suitable method for reducing the video file size without compromising video quality.

This is the key reason website creators prefer SWF – videos can be uploaded on their websites without significantly impacting the page load speeds.
