Generation loss — quality may degrade
AVI 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.
Some metadata may not survive
Your AVI file may contain RIFF chunks metadata. MTS 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
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 AVI to MTS Conversion
AVI (introduced 1992) and MTS (introduced 2006) are both video formats, but they differ in important ways. AVI (Audio Video Interleave) is Microsoft's legacy video container, widely compatible but often large. MTS (AVCHD) is the format from camcorders recording in high-definition AVCHD.
Full Name: AVI uses Audio Video Interleave, while MTS uses AVCHD Video. Compression: AVI uses Lossy, while MTS uses Lossy. Color Depth: AVI uses 8-bit, while MTS uses 8-bit.
When you convert AVI to MTS, the goal is to upgrade to a modern format. AVI 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 AVI file is decoded and re-encoded as MTS. The conversion involves 4 steps: (1) your avi 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 AVI conversion.
How to Convert AVI to MTS
- 1
Upload .avi file
Select your AVI 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 AVI→MTS conversion profile.
- 3
Convert
The server-side engine decodes your AVI 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 AVI to MTS
Your AVI 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 AVI 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 AVI 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 AVI to MTS
"I'll convert to MTS and then back to AVI — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going AVI → MTS → AVI will produce a noticeably worse file than the original. Always keep your source file.
