  • →Test a short clip before converting the entire MP4 file — this confirms 3GP settings produce acceptable quality
  • →3GP 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
  • →Keep the original file in case you need to re-encode with different settings
  • →Check audio sync after conversion — container changes can sometimes cause drift
