Generation loss — quality may degrade
MTS uses lossy compression, and so does TS. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your MTS file may contain AVCHD metadata metadata. TS has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
TS lossy compression can produce codec-dependent (usually MPEG-2 blockiness). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

About MTS to TS Conversion
MTS (introduced 2006) and TS (introduced 1995) are both video formats, but they differ in important ways. MTS (AVCHD) is the format from camcorders recording in high-definition AVCHD. TS (MPEG Transport Stream) is used in broadcast television and is segmented for streaming.
Full Name: MTS uses AVCHD Video, while TS uses MPEG Transport Stream. Compression: MTS uses Lossy, while TS uses Lossy. Color Depth: MTS uses 8-bit, while TS uses 8-bit.
When you convert MTS to TS, the goal is to improve file compatibility across devices. MTS uses lossy compression, and so does TS. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible. Understanding these technical differences helps you choose the right format for your workflow.
Your MTS file is decoded and re-encoded as TS. The conversion involves 4 steps: (1) your mts file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in ts format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you Your MTS file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts TS uploads. For the opposite direction, CocoConvert also supports TS to MTS conversion.
How to Convert MTS to TS
- 1
Upload .mts file
Select your MTS file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .ts
Set TS as the output format. The converter uses optimal settings based on the MTS→TS conversion profile.
- 3
Convert
The server-side engine decodes your MTS file and re-encodes it as TS. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .ts file. Multiple output files can be downloaded together.
What Happens When You Convert MTS to TS
Your MTS video is transcoded — video and audio streams are decoded and re-encoded into the TS container. This is a lossy process that takes time proportional to the video duration.
Your MTS file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with TS-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the TS container and the file is saved

Should You Convert MTS to TS?
When to Convert
- ✓Your MTS file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts TS uploads
When NOT to Convert
- ✗You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
Common Mistakes When Converting MTS to TS
"I'll convert to TS and then back to MTS — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going MTS → TS → MTS will produce a noticeably worse file than the original. Always keep your source file.
Frequently Asked Questions
What is the difference between MTS and TS?
MTS (AVCHD) is the format from camcorders recording in high-definition AVCHD. TS (MPEG Transport Stream) is used in broadcast television and is segmented for streaming. Full Name: MTS uses AVCHD Video, while TS uses MPEG Transport Stream. Compression: MTS uses Lossy, while TS uses Lossy. Color Depth: MTS uses 8-bit, while TS uses 8-bit.
Does MTS to TS conversion affect quality?
MTS uses lossy compression, and so does TS. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Which format has better compression, MTS or TS?
MTS uses lossy compression. TS uses lossy compression. The better choice depends on whether you prioritize file size or quality.
How long does MTS to TS conversion take?
Most conversions finish in seconds. Larger files or complex video content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is MTS or TS better for long-term storage?
Both formats use lossy compression, so consider keeping your original source file for long-term storage.
