Although MP4 has taken over contemporary video, FLV has its niche but significant purposes. It is still required by some web players, editing systems and projects, and conversion is a viable process. If you want to turn MP4 into FLV without losing quality and wasting time, there are options that will balance performance and simplicity.

Why Convert MP4 to an "Outdated" Format?

At first glance, the debate of FLV vs MP4 seems simple. MP4 is the modern winner, offering better compression, high-definition quality, and universal support across devices, browsers, and platforms. It is the format of choice for YouTube, mobile streaming, and most professional projects.

But FLV does not absolutely disappear. This format used to be the mainstay of video on the internet, and it still performs niche yet significant functions. Its lightweight design and quick loading render it useful in some features where MP4 is less effective. Today, FLV is still used for:

• Legacy systems and websites - Most older systems and content libraries are only capable of playing FLV.

• Low-bandwidth streaming - Smaller file sizes are useful to users who have slower internet connections.

• E-learning platforms - E-learning tools can be used to stream lessons with faster videos using FLV.

• Digital advertising - Advertising networks usually favor FLV when embedding videos, which are short advertisements.

• Archiving older content - MP4 to FLV ensures that the file is compatible with old video editing or viewer programs.

In short, while MP4 is the standard, FLV continues to serve in areas where speed, size, or legacy support are more important than cutting-edge quality.
