About FLV to MP4 conversion
The video inside the FLV container is re-encoded to standard MP4, viewable on any modern device. Conversion runs locally — old archives never need to be uploaded anywhere.
Good to know: Re-encoding in the browser takes a few minutes per video minute. Keep the tab open until it finishes.
