HOW TO CONVERT H264 → TS
Upload the H264
Drop your H264 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 TS
Fetch the converted TS as soon as it is ready. Both files auto-delete within two hours.
H264 is a video container, so playback depends on the codec inside as well as the wrapper itself. Reaching a TS from there is one hop. Converting H264 to TS changes how the video is packaged without re-recording it. Most H264 to TS 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 H264 intact. Worth knowing: H264 is a video container, so playback depends on the codec inside as well as the wrapper itself. Meanwhile TS is the MPEG transport stream, used in broadcast and HLS streaming segments.
Why convert H264 to TS
MPEG Transport Stream is better supported than H.264 Raw Stream across web uploads, social networks and consumer devices. Converting trades the niche advantages of H264 for broad playback and fewer "file type not supported" messages. Stream copy (when codecs match) keeps the video bit-identical to the source.

H264 vs TS — Strengths and limitations
What each format does best, and where it falls short.
H264 Strengths
- Universal hardware decode on every device since ~2010.
- 40-50% smaller than MPEG-2 at equal quality.
- Mature ecosystem with dozens of encoders (x264 is the open-source gold standard).
- Every browser, phone, TV, and car infotainment supports H.264.
- Supports everything from 144p vertical phone video to 8K HDR masters.
Limitations
- Patent-encumbered — encoding royalties apply for commercial use.
- 30-50% larger than H.265/AV1 at equivalent quality.
- Raw .h264 bytestreams have no timecode — containers (MP4/MKV) add that.
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).
Quality & Compatibility
Stream-copy is bit-perfect: when the codecs inside H264 match what TS 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 H264 already uses TS-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 H264 if you plan further editing — transcoded TS is fine for final delivery but not for intermediate edits.
Frequently Asked Questions
Only when it has to. If the codecs inside H264 (usually H.264 or H.265 for video, AAC for audio) are accepted by TS, 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".
H.264 Raw Stream
Source formatH.264 raw stream is an elementary bitstream containing only the video data encoded with the H.264/AVC codec without any container. It is commonly used as an intermediate format in video processing pipelines and for hardware encoder output.
MPEG Transport Stream
Target formatTS (Transport Stream) is used for broadcasting, streaming, and recording live TV.
Common Use Cases
Share across platforms
Send TS files to anyone without worrying about whether they have the right software for H264.
Embed in documents
Drop TS output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
TS often produces smaller files than H264 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.
