3GP to MP4 Converter

Common output settings

Advanced video, audio, and stream settings

Lower CRF values preserve more detail and usually create larger files.

The private batch workspace is ready. Video encoding becomes available after the verified browser engine is loaded.

How 3GP to MP4 conversion works

3GP probe and decode → stream-aware conversion → MP4 verify

Reading 3GP

3GP input reads unencrypted mobile-media containers with supported H.263, H.264, or MPEG-4 Part 2 video.

Creating MP4

MP4 output uses the approved H.264/AAC profile after its distribution rights and browser encoder are approved.
