SWF is a legacy file format, developed by Adobe for the Shockwave Flash player, and became a standard browser-based method of displaying audio and video during the 2000s and 2010s, particularly in games. Due to performance and security issues, Flash is no longer supported by many browsers, was never supported by iOS devices and the SWF file type is rarely used these days.
MP4 is an international standard and probably the most popular video and audio file container at present, with native support in Windows, Macs, iOS, and Android devices. Although the format is lossy, this enables small file sizes, whilst retaining a good level of video quality.
You may want to convert SWF files to MP4 because Flash players are increasingly unsupported and you can no longer play the SWF files, or you want to edit the original SWF in a video editing platform.
NOTE: It's important to distinguish between file container formats and compression formats, or codecs. For example, MP4 is a container, and can hold different types of video compression, for example, MPEG-2 Part 2, MPEG-4 AVC, or HEVC, as well as audio (again compressed in a variety of formats) and metadata (for example subtitles). Some codecs can be wrapped in multiple different containers. Containers are sometimes referred to as file extensions, e.g. MOV, MP4, or AVI, but it's important to remember that there can be different types of video within these file formats.
VideoStudio is more than SWF to MP4 converter. We built VideoStudio to convert multiple file-formats including the formats below.
