HOW TO CONVERT TS → 3GP
Upload the TS
Drop your TS onto the uploader. Files up to 25 MB run on the free tier without registration; paid plans go up to 2 GB.
Stream-copy or re-encode
FFmpeg probes the codecs; if compatible, it stream-copies (no quality loss). Otherwise it transcodes at matching bitrate.
Download the 3GP
Fetch the converted 3GP as soon as it is ready. Both files auto-delete within two hours.
Situation. TS is the MPEG transport stream, used in broadcast and HLS streaming segments. Solution: a 3GP, produced below. Converting TS to 3GP changes how the video is packaged without re-recording it. Most TS to 3GP jobs are about getting the file to open on a platform that refuses the original container — an upload form, a social app, an older media player. KaijuConverter uses FFmpeg to either stream-copy (no re-encoding, zero quality loss) or transcode when codecs differ, and keeps the original TS intact. Keep in mind TS is the MPEG transport stream, used in broadcast and HLS streaming segments. And remember that 3GP is the mobile video container standardised by 3GPP for early smartphones.
Why convert TS to 3GP
3GPP Video is better supported than MPEG Transport Stream across web uploads, social networks and consumer devices. Converting trades the niche advantages of TS for broad playback and fewer "file type not supported" messages. Stream copy (when codecs match) keeps the video bit-identical to the source.

TS vs 3GP — Strengths and limitations
What each format does best, and where it falls short.
TS Strengths
- Designed for noisy channels — packet-level error correction.
- Multi-program: one TS can carry several TV channels.
- Native format for all digital TV broadcasts and HLS streaming.
- Streaming-first: no need to download whole file to start playing.
- 30+ years of stable, deployed infrastructure.
Limitations
- Packet overhead (~3% vs Program Stream).
- Seek index is implicit — requires scanning for random access.
- Multiple audio/subtitle selection requires parsing PMT (Program Map Tables).
3GP Strengths
- Extremely low bitrate and file size — great for 2G/3G networks.
- Universal playback in feature phones and early smartphones.
- Based on MP4 — easy to convert and handle with modern tools.
- Mandatory codec in every 3G device since 2001.
Limitations
- Tiny resolutions — rarely above 320×240 in practice.
- H.263 video is far behind H.264 in compression efficiency.
- Metadata support is minimal.
Quality & Compatibility
Stream-copy is bit-perfect: when the codecs inside TS match what 3GP can carry, the frames are copied across without re-encoding and the output is visually identical to the source. When transcoding is required, we target CRF 20–23 H.264 — visually transparent for most content — and keep audio bitrate at 192 kbps AAC.
Tips for Best Results
- Stream-copy beats re-encoding by orders of magnitude — check if your TS already uses 3GP-compatible codecs before picking Advanced settings.
- For social uploads, 1080p at 30 fps strikes the best quality-to-size ratio; 4K is often downscaled server-side anyway.
- Keep the TS if you plan further editing — transcoded 3GP is fine for final delivery but not for intermediate edits.
Frequently Asked Questions
Only when it has to. If the codecs inside TS (usually H.264 or H.265 for video, AAC for audio) are accepted by 3GP, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
MPEG Transport Stream
Source formatTS (Transport Stream) is used for broadcasting, streaming, and recording live TV.
3GPP Video
Target format3GP is a multimedia container designed for 3G mobile phones. It stores video and audio at low bitrates optimized for limited bandwidth. Many early mobile phone recordings use this format.
Going the other way? Convert 3GP back to TS with the same engine.
Common Use Cases
Share across platforms
Send 3GP files to anyone without worrying about whether they have the right software for TS.
Embed in documents
Drop 3GP output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
3GP often produces smaller files than TS for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
