AVCHD to TS Converter

AVCHD to TS Converter

AVCHD is the HD camcorder format from Sony and Panasonic — H.264 video with Dolby AC-3 audio wrapped in an MPEG-2 transport stream, saved as .mts or .m2ts inside an AVCHD folder. TS (.ts) is the same MPEG-2 transport stream container used for broadcast television and HLS streaming. Because both already carry H.264, this conversion is largely a re-container: the video stream can pass through untouched while the file is repackaged as a plain .ts that broadcast encoders, IPTV players, and streaming pipelines accept.

How to Convert AVCHD to TS

1. Upload Your AVCHD File: Drag and drop your .mts or .m2ts file, or click "Add Files". You can queue several clips and convert them with the same settings.
2. Confirm the Output Codec: TS output defaults to H.264 video with AAC audio. Open Advanced Options to switch the audio codec to AC-3 if your broadcast or IPTV target expects Dolby Digital.
3. Set Quality or Resolution (Optional): Use the Preset dropdown (defaults to Very High) or Video resolution to keep the original 1080p, downscale with a preset, or target a specific file size.
4. Convert and Download: Click Convert and save your .ts file. No sign-up, no watermark.

Frequently Asked Questions

Will converting AVCHD to TS reduce video quality?

Not necessarily. AVCHD already stores H.264 inside an MPEG-2 transport stream, so moving to .ts is close to a re-wrap of the same video. When the H.264 stream is carried over without re-encoding, the picture is preserved. Quality only changes if you re-encode — for example by lowering the resolution, capping the file size, or switching the video codec in Advanced Options.

Does the audio change when I convert to TS?

It can. AVCHD audio is usually Dolby AC-3 or linear PCM. Our TS output defaults to AAC, which most players and HLS pipelines expect, so the audio is re-encoded by default. If your target needs Dolby Digital, set the audio codec to AC-3 in Advanced Options to keep it as AC-3.

What is the difference between TS, MTS, and M2TS?

All three are MPEG-2 transport streams carrying H.264 (or MPEG-2) elementary streams — the difference is mainly the extension and context. .mts and .m2ts are the AVCHD camcorder variants, while plain .ts is the generic transport stream used for broadcast and HLS. Converting AVCHD to .ts produces a container that broadcast tools and .ts-based streaming workflows recognize directly.

Why convert to TS instead of MP4 for streaming?

TS is the historical segment format for HTTP Live Streaming (HLS) — adaptive streams are split into short .ts chunks referenced by an .m3u8 playlist — and it tolerates transmission errors well thanks to its 188-byte packet structure, which is why broadcast (DVB, ATSC, ISDB) relies on it. For general playback on phones, browsers, and editors, MP4 is the more universal and lower-overhead choice.

Can I play a .ts file on my computer?

Yes. VLC, MPV, and most IPTV players and set-top boxes play .ts files directly. Some general-purpose players and video editors prefer MP4 or MKV; if a .ts file will not open in your editor, convert AVCHD to MP4 or MKV instead.

Are my uploaded files kept private?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and your files are never shared or made public.
