How do I convert an FLV file to AVS?

Click the 'Upload' button to select your FLV video, then choose AVS as the output codec. Adjust the bitrate, resolution, and frame rate if desired (or keep original). Hit 'Convert' and wait for the re-encoding to finish, then download the .avs file. The conversion supports batch processing, so you can queue multiple FLVs at once.

Why should I convert FLV to AVS instead of keeping FLV?

FLV is a web-oriented container with H.264/VP6 video, but many set-top boxes, DVB receivers, and Chinese smart TVs natively support AVS (Audio Video Standard). Converting to AVS ensures compatibility with those devices and provides better compression—typically 30-50% smaller files at the same quality—making it ideal for broadcast and storage.

What happens to video quality and metadata when converting FLV to AVS?

AVS encoding is lossy, so the video stream is recalculated. The tool preserves resolution, aspect ratio, and frame rate, but bitrate is re-quantized. Color profiles are kept in BT.709 unless overridden. Audio is transcoded to AAC or MP3; e.g., 5.1 channels are retained if the output container supports them. Subtitles and metadata are not carried over, so export them separately if needed.
