Both containers can carry H.264, so this conversion is largely a container change rather than a full re-encode. That keeps quality intact and makes it fast.
This conversion buys reach. Unlike 3GP, M4V is natively supported on macOS and iOS, which is usually the reason people convert in this direction.
Expect the bitrate to move from roughly 1.1 Mbps to about 12 Mbps at 1080p, and file size to follow.
Converting 3GP to M4V moves the video from the 3GPP container, introduced in 2001, into MPEG-4 (Apple variant), which arrived in 2005. 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.
M4V was introduced by Apple in 2005. It carries H.264 video with AAC or AC-3 audio and plays natively on macOS and iOS.
