Frequently asked questions
Will the MKV 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 MKV re-encode the video?
Yes, almost always: MKV accepts any codec, so streams are copied in seconds. A typical 3GP contains H.263 or H.264 video with AMR or AAC audio. Otherwise the result is H.264 with AAC audio.
