This is a full transcode rather than a container swap, because H.263 is not one of the codecs MPEG carries. Every frame is decoded and re-encoded as MPEG-1.
If the source has subtitles baked in as a separate track, they will not survive: MPEG does not support embedded subtitle streams.
Expect the bitrate to move from roughly 1.1 Mbps to about 5.5 Mbps at 1080p, and file size to follow.
MPEG dates from 1993 and is not natively supported by modern browsers, so plan on a desktop media player for playback.
Converting 3GP to MPEG moves the video from the 3GPP container, introduced in 2001, into MPEG-1/2 Program Stream, which arrived in 1993. Whether the picture is re-encoded or copied across depends on the codecs both containers accept.
Developed by 3GPP in 2001, 3GP carries H.263, MPEG-4 Part 2, or H.264 video and AMR-NB, AMR-WB, or AAC-LC audio. That combination sets the upper bound on what any conversion can preserve.
MPEG was introduced by MPEG in 1993. It carries MPEG-1 or MPEG-2 video with MP2 or MP3 audio and plays natively on Windows.
