MPG is a legacy video format using MPEG-1 or MPEG-2 compression — the codecs that powered Video CDs (352x240 at 1.5 Mbps) and DVD discs (up to 1920x1080). MPG files typically pair MPEG-1/2 video with MP2 (MPEG Audio Layer 2) audio. 3GP is the mobile video container designed for GSM cellular networks, using H.263 or MPEG-4 Part 2 video at very low bitrates. Converting MPG to 3GP transforms legacy disc and broadcast video into an ultra-compact format playable on feature phones and 2G/3G mobile devices.
3GP was engineered for scenarios where MPG files are far too large to transmit — over MMS, slow cellular networks, or onto phones with megabytes (not gigabytes) of storage. A DVD-quality MPG file at 5-8 Mbps would consume data budgets in minutes. 3GP at 64-384 kbps total makes the same content viewable on legacy Nokia, Motorola, and Samsung feature phones that dominated the pre-smartphone era.
FFmpeg decodes the MPEG-1 or MPEG-2 video and MP2 audio from the MPG container, then re-encodes the video to H.263 at QCIF (176x144) or CIF (352x288) resolution and the audio to AMR-NB at 8 kHz for maximum compatibility. The output is wrapped in the 3GP container. Frame rates are reduced to 12-15 fps and total bitrate is kept under 384 kbps to meet 3GP specifications.
The quality drop is dramatic. DVD-quality MPG (720x480 at 5 Mbps) becomes a postage-stamp-sized 176x144 video at 128 kbps. VCD-quality MPG fares slightly better since it was already low resolution. For speech and simple video, the result is usable. For action-heavy content, expect heavy blocking and blurriness.

MPG to 3GP conversion bridges the gap between legacy disc/broadcast video and ultra-constrained mobile devices. It sacrifices significant quality for the extreme portability that 3GP provides on feature phones and slow networks.
