When you need to play videos on legacy Flash players or embedded devices, our FLV converter quickly transforms mainstream video formats into the highly compatible FLV (Flash Video) format. Using streaming media encoding technology, this tool remuxes video streams from MP4, AVI, and other containers into .flv files. It preserves the original video quality while ensuring smooth playback in traditional environments.
Q: Does the FLV format support H.265 encoding?
No. FLV is only compatible with H.264/AVC and VP6 video encoding.
Q: Will the audio be lost after conversion?
No. The tool preserves the original audio stream and converts it into an FLV-compatible MP3 or AAC format.
We recommend keeping individual files under 500MB. The converted FLV files do not include DRM protection. Closing the page will interrupt the conversion process.
For presentation videos that need to be embedded in web pages, we recommend a combination of 854x480 resolution and an 800kbps bitrate to achieve the best balance between file size and clarity. Typical conversion example: Input MP4 (H.264/AAC) → Output FLV (VP6/MP3).
