A(z) AVI – 3GP konverzióról

AVI (Audio Video Interleave) files use Microsoft's RIFF container structure, often holding DivX or XviD-encoded video at resolutions up to 1080p. 3GP (3GPP Multimedia) is a lightweight container designed by the 3rd Generation Partnership Project specifically for mobile networks, typically carrying H.263 or MPEG-4 Part 2 video at QCIF (176x144) or CIF (352x288) resolution. Converting AVI to 3GP transcodes the video into a mobile-optimized codec and drastically reduces file size — a 700 MB AVI can shrink to under 15 MB as 3GP.

Miért érdemes AVI fájlt 3GP formátumba konvertálni?

3GP was engineered for bandwidth-constrained 2G/3G mobile networks where every kilobyte matters. If you have AVI files from a camcorder or screen recorder and need to send them via MMS, share on older feature phones, or upload to services with strict mobile format requirements, 3GP delivers the smallest possible file. Many legacy Nokia, Samsung, and Motorola handsets only play 3GP natively.

Hogyan működik

The converter decodes AVI's video stream (DivX, XviD, MJPEG, or H.264) and audio stream (PCM, MP3, or AC3) using FFmpeg, then re-encodes video to H.263 or MPEG-4 Part 2 at mobile-friendly bitrates (64–256 kbps) and audio to AMR-NB at 12.2 kbps or AAC-LC at 32 kbps. Resolution is downscaled to 176x144 (QCIF) or 320x240 depending on the quality preset. Frame rate is typically capped at 15 fps to keep the output size minimal.

Minőség és teljesítmény

Expect significant visual quality reduction since 3GP targets extremely low bitrates. Fine details, fast motion, and color gradients will show compression artifacts. Audio is reduced to narrowband (AMR-NB) or low-bitrate AAC, which sounds acceptable for speech but noticeably degrades music. For the best 3GP result, choose the highest bitrate preset the target device supports.

Tippek a legjobb eredményekhez

1Choose AMR-NB audio for speech-heavy content (interviews, lectures) and AAC for music or mixed audio to maximize quality within 3GP constraints.
2If your AVI uses an interlaced scan (common in DV camcorder footage), apply deinterlacing before conversion to avoid combing artifacts in the smaller 3GP frame.
3Test the output on the actual target device — 3GP playback compatibility varies between phone manufacturers and firmware versions.
4For the best balance of size and quality, use CIF resolution (352x288) at 192 kbps video bitrate with AAC audio at 48 kbps.
5Consider converting to MP4 (H.264) instead if the target device is a modern smartphone — you will get dramatically better quality at similar file sizes.

AVI to 3GP conversion is ideal when you need the smallest possible video file for mobile delivery. While quality is limited by the 3GP specification, the format remains relevant for MMS, feature phones, and ultra-low-bandwidth scenarios.

Gyakran ismetelt kerdesek

3GP has limited subtitle support. Soft subtitles embedded in AVI (SRT, SSA) are typically stripped during conversion. If you need text overlays, burn them into the video as hard subtitles before converting.

QCIF (176x144) is the safest choice for maximum compatibility with feature phones. CIF (352x288) works on smartphones and offers noticeably better clarity. QVGA (320x240) is a good middle ground.

Android plays 3GP natively. iPhones can open them but may show quality limitations. Modern phones are better served by MP4 (H.264), but 3GP remains useful when file size is the primary constraint.

Typically 95–98% smaller. A 700 MB AVI at DVD resolution often converts to 10–20 MB in 3GP at CIF resolution, depending on the chosen bitrate and duration.

Most AVI metadata (title, author, creation date) is not carried into 3GP. If metadata preservation matters, note the original details before converting.

3GP typically uses AMR-NB audio at 12.2 kbps, which was designed for voice calls, not music. Switch to AAC-LC audio codec at 64 kbps or higher for better fidelity if your target device supports it.
