When to convert FLV to MP4

Reuse a downloaded FLV recording as an MP4 file. This tool converts video files, not interactive Flash applications.

What the output contains

Video conversion first tries to keep compatible streams. If that fails, it encodes H.264 video and AAC audio.

Keep the original recording. The converter does not promise identical file size, metadata, or playback support across every application.

Before using the converted file

Play the beginning and ending of the MP4. Confirm that speech stays aligned with the picture throughout the recording.

How to convert your FLV file

  1. Upload the recording

    Choose your FLV file from your device. The upload limit is 500 MB.

  2. Start the conversion

    The output is already set to MP4. Complete the verification and choose Convert.

  3. Download and check

    Wait for processing, then download the result. Open it in the application where you plan to use it.
