How to convert .mp4 videos to .3ga format.
Converting MPEG-4 Videos directly to 3GPP Audio Files (.mp4 to .3ga conversion) should be possible and straightforward. It relates to users attempting to extract the audio track (3GA) from an MP4 video.
Try using video editing programs or conversion tools, such as SUPER or FormatFactory, which should allow users to import MP4 videos and re-save them in 3GA format.
