Generation loss — quality may degrade
MPEG uses lossy compression, and so does MTS. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
What compression artifacts to expect
MTS lossy compression can produce blockiness (H.264). 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 MPEG to MTS Conversion
MPEG (introduced 1993) and MTS (introduced 2006) are both video formats, but they differ in important ways. MPEG is an early standard for video compression — the foundation for modern codecs like H.264. MTS (AVCHD) is the format from camcorders recording in high-definition AVCHD.
Full Name: MPEG uses MPEG Video, while MTS uses AVCHD Video. Compression: MPEG uses Lossy, while MTS uses Lossy. Color Depth: MPEG uses 8-bit, while MTS uses 8-bit.
When you convert MPEG to MTS, the goal is to upgrade to a modern format. MPEG uses lossy compression, and so does MTS. 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 MPEG file is decoded and re-encoded as MTS. The conversion involves 4 steps: (1) your mpeg 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 mts 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 When you specifically need a MTS file for your workflow. For the opposite direction, CocoConvert also supports MTS to MPEG conversion.
How to Convert MPEG to MTS
- 1
Upload .mpeg file
Select your MPEG file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .mts
Set MTS as the output format. The converter uses optimal settings based on the MPEG→MTS conversion profile.
- 3
Convert
The server-side engine decodes your MPEG file and re-encodes it as MTS. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .mts file. Multiple output files can be downloaded together.
What Happens When You Convert MPEG to MTS
Your MPEG video is transcoded — video and audio streams are decoded and re-encoded into the MTS container. This is a lossy process that takes time proportional to the video duration.
Your MPEG file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with MTS-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 MTS container and the file is saved

Should You Convert MPEG to MTS?
When to Convert
- ✓When you specifically need a MTS file for your workflow
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 MPEG to MTS
"I'll convert to MTS and then back to MPEG — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going MPEG → MTS → MPEG will produce a noticeably worse file than the original. Always keep your source file.
Frequently Asked Questions
What is the difference between MPEG and MTS?
MPEG is an early standard for video compression — the foundation for modern codecs like H.264. MTS (AVCHD) is the format from camcorders recording in high-definition AVCHD. Full Name: MPEG uses MPEG Video, while MTS uses AVCHD Video. Compression: MPEG uses Lossy, while MTS uses Lossy. Color Depth: MPEG uses 8-bit, while MTS uses 8-bit.
Does MPEG to MTS conversion affect quality?
MPEG uses lossy compression, and so does MTS. 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, MPEG or MTS?
MPEG uses lossy compression. MTS uses lossy compression. The better choice depends on whether you prioritize file size or quality.
How long does MPEG to MTS 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 MPEG or MTS better for long-term storage?
Both formats use lossy compression, so consider keeping your original source file for long-term storage.
