Frequently asked questions
Will the MP4 lose quality?
Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.
Does converting 3GP to MP4 re-encode the video?
Sometimes: it depends on the codec inside your file, and Smart mode checks this automatically. A typical 3GP contains H.263 or H.264 video with AMR or AAC audio. Otherwise the result is H.264 with AAC audio.
