O převodu MPEG na 3GP

MPEG files, based on the MPEG-1 and MPEG-2 standards developed by the Moving Picture Experts Group, were the backbone of early digital video from VCDs to DVDs. 3GP is a stripped-down multimedia container designed by the 3rd Generation Partnership Project specifically for 3G mobile networks, using H.263 or MPEG-4 Part 2 video with AMR audio. Converting MPEG to 3GP compresses legacy video into tiny files optimized for low-bandwidth mobile streaming.

Proč převádět MPEG na 3GP?

MPEG-1 and MPEG-2 files are far too large and resolution-heavy for older mobile phones that only support 3GP playback. A typical MPEG-2 DVD rip at 720x480 and 5 Mbps would overwhelm a feature phone's processor and storage, while 3GP at 176x144 and 64 kbps fits perfectly within the constraints of 2G and 3G networks.

If you maintain a library of legacy broadcast recordings or VCD archives and need to distribute clips to users in regions where feature phones remain common, converting to 3GP ensures universal accessibility. The format's AMR-NB audio codec is also ideal for voice-centric content where speech clarity matters more than music fidelity.

Jak to funguje

FFmpeg decodes the MPEG-1/2 video stream and MPEG Audio Layer 2 soundtrack, then re-encodes to H.263 video at QCIF resolution (176x144) with AMR-NB audio at 12.2 kbps inside a 3GP container. The command typically uses `-vcodec h263 -s 176x144 -r 15 -acodec libopencore_amrnb -ar 8000 -ac 1`. For slightly better quality on modern phones, MPEG-4 Part 2 can be used instead of H.263.

Kvalita a výkon

Expect significant quality reduction since you are downscaling from DVD-grade MPEG-2 (up to 1920x1080) to QCIF resolution. The output is suitable for small-screen viewing only. Speech remains intelligible through AMR encoding, but music and ambient sound lose substantial detail. File sizes typically drop by 95% or more.

Tipy pro nejlepší výsledky

1Use H.263 codec for maximum device compatibility on feature phones, or H.264 Baseline for slightly better quality on smartphones
2Set frame rate to 15 fps to reduce file size without noticeably impacting the small-screen viewing experience
3Choose mono audio (1 channel) at 8000 Hz sample rate — stereo is wasted at AMR bitrates
4If the source MPEG has interlaced video (common for broadcast recordings), apply deinterlacing before downscaling to avoid combing artifacts
5Test the output on the target device before batch-converting an entire archive — 3GP decoder support varies between phone manufacturers

MPEG to 3GP conversion bridges the gap between legacy broadcast-quality archives and the constraints of basic mobile devices, producing extremely compact files that play on virtually any phone ever made.

Často kladené otázky

No — 3GP is designed for tiny screens (176x144 to 352x288). The conversion drastically reduces resolution and bitrate. It is only suitable for feature phone displays, not for viewing on tablets or monitors.

AMR-NB encodes at 4.75-12.2 kbps, which is adequate for speech but poor for music. If your MPEG contains a musical soundtrack, expect noticeable loss of high frequencies and stereo imaging.

Technically you can use H.264 Baseline inside 3GP (3GP version 6), which supports higher resolutions. However, older phones may not decode it. For maximum compatibility, stick with H.263 at QCIF or CIF.

A 700MB MPEG-1 VCD file typically converts to 3-8MB as 3GP, depending on duration and target bitrate. The compression ratio is extreme because both spatial resolution and temporal detail are reduced.

In developed markets, 3GP has been superseded by MP4. However, in parts of Africa, South Asia, and Southeast Asia, feature phones using 3GP remain in active use. It is also the lightest standard video format available.

Yes. Upload multiple MPEG files and they will be converted sequentially. Each file is processed independently with its own encoding settings.
