What happens when 3GP becomes MP4
Στόχος μορφή
MP4 is a widely supported media container, commonly carrying H.264 or H.265 video and AAC audio.
Τι αλλαγές
The 3GP container is read and the selected video and audio streams are written into a MP4 container.
Codecs may be transcoded even when the visible resolution and duration stay the same.
- Τι διατηρείται
- Duration, frame order, and visible dimensions are preserved unless you select trimming, frame-rate, or resolution changes.
- What may be lost
- Extra subtitle, attachment, chapter, or alternate audio tracks may be omitted when the target container or selected settings do not support them.
- Codec and quality implications
- Container names do not guarantee a codec. Quality and compatibility depend on the selected video codec, audio codec, bitrate, frame rate, and resolution.
- Realistic limitations
- A valid 3GP extension does not guarantee that every codec inside the container is decodable. Corrupt, encrypted, or unusual streams can fail.
Βήματα μετατροπής
- Upload a 3GP file no larger than 1 GB.
- Confirm that MP4 is selected as the target.
- Open settings only if you need to change codec, quality, bitrate, frame rate, resolution, or audio behavior.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the MP4 file and check the result before deleting your source.
Διαταραχές
- The 3GP file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The MP4 file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- The result has no sound or will not play.
- Try a broadly supported target codec and verify that the source contains a decodable audio stream.
