Upload your MP4 file and set Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The 3GP output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. N'ebe ọ bụla MP4 n'oké ọhịa bụ H.264 vidiyo na AAC audio; container na-echekwa HEVC, AV1 na VP9. 3GP na-echekwa H.263 ma ọ bụ MPEG-4 Part 2 video na AMR narrowband okwu ụda, niile tuned maka minimal bitrate kama nke ọma.

It depends on the 3GP container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for.
Ọ ga-adị ndụ n'ịgbanwe ụda m site na MP4 gaa na 3GP?
+
Yes, the main audio track comes through, re-encoded to a codec the 3GP container plays, for example AAC in MP4 and MOV or Opus in WebM. Most conversions keep only that one track (the one with the most channels), so alternate languages and commentary are dropped. MP4 to MOV, and AVI, WMV, MPEG, FLV, VOB or M4V to MKV, keep every audio track.
