What is an FLV File?

FLV, or Flash Video, is a format used to deliver video content over the internet using Adobe Flash Player.

Key Advantages of FLV Files:

Streaming: FLV is optimized for online streaming and widely used for embedded video on websites.

Compression: FLV files are relatively small due to efficient compression techniques.

Limitations of FLV Files:

Compatibility: FLV is becoming less common as Flash Player is phased out and replaced by newer technologies.

Quality: FLV may not offer the same level of quality as newer formats like MP4.


FLV was once a standard for web video, but its usage is declining in favor of newer formats with better compatibility and quality.

What is an H.265 File?

H.265, also known as HEVC (High Efficiency Video Coding), is a video compression standard designed to succeed H.264, offering even better compression and quality.

Key Advantages of H.265 Files:

Quality: H.265 provides superior video quality at lower bitrates, making it ideal for high-definition and 4K video.

Compression: H.265 offers efficient compression, reducing file sizes while maintaining quality.

Limitations of H.265 Files:

Compatibility: H.265 is newer and may not be supported by all older devices and media players.
