What is FLV
FLV is a video format developed by Adobe Systems, known as Flash Live Video. It is designed to embed video streams in Adobe applications and for use with the Flash plugin. FLV files are small, load quickly, and are convenient for watching videos online. However, they have been replaced by HTML5 due to power consumption and security issues.

- Has good quality and loads faster.
- FLV files are very easy to watch on the Internet. Many video networks use the FLV format, which is widely used on the Internet.
- Can be a great help for websites looking to add animation and interactive content.
shortcoming:
- You need to install the FLAsh plug-in to play Flash files online.
- The compatibility of the Flash video format is average, and it cannot be played on iOS devices.
What is MP3
MP3, short for MPEG Layer 3, is the most common lossy compressed digital audio format with bit rates from 8 kbit/s to 320 kbit/s and sampling rates from 16 kHz to 48 kHz. Despite its high compression rate, MP3 maintains good audio quality suitable for ordinary listeners. Music enthusiasts may prefer lossless audio formats for better listening enjoyment.
advantage:
- Smaller file sizes store more data in the same storage space than uncompressed audio formats.
- MP3 files can be easily shared on the Internet or on storage devices (USB/CD).
- Widely supported by almost all music players and smart devices (computers/phones, etc.).
- ID3 tags, which can store artist name, song title, year and genre on ID3 tags in MP3.
- Download and upload times are significantly reduced relative to the time taken in the uncompressed format.
- The compression ratio of MP3 is not fixed, and users can choose the desired compression size by weighing the file size and audio quality.
- Fast decoding, less complex than AAC or Vorbis.
shortcoming:
- Audio quality is lower than lossless or uncompressed audio.
- MP3 lacks digital rights protection (DRM) and is prone to music piracy.
- Vulnerable to malware or virus attack, resulting in data loss.
