  • →Test a short clip before converting the entire 3GP file — this confirms MP4 settings produce acceptable quality
  • →MP4 is widely supported but choose bitrate carefully to balance quality and file size
  • →Use constant bitrate (CBR) for streaming delivery and variable bitrate (VBR) for archival storage
