M2TS to FLV — Format Comparison & Online Converter
Fast, instant M2TS to FLV conversion. No signup required. Just drop your .m2ts file and get .flv in seconds.
Batch Settings
Generation loss — quality may degrade
M2TS uses lossy compression, and so does FLV. 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 M2TS file may contain Blu-ray metadata metadata. FLV 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
FLV lossy compression can produce blockiness, banding. 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 M2TS to FLV Conversion
M2TS (introduced 2006) and FLV (introduced 2002) are both video formats, but they differ in important ways. M2TS is the Blu-ray disc transport stream format used for high-definition recordings. FLV (Flash Video) is a legacy streaming format — converting to MP4 is recommended for modern use.
Full Name: M2TS uses Blu-ray Transport Stream, while FLV uses Flash Video. Compression: M2TS uses Lossy, while FLV uses Lossy. Color Depth: M2TS uses 8-bit, while FLV uses 8-bit.
When you convert M2TS to FLV, the goal is to convert between formats quickly. M2TS uses lossy compression, and so does FLV. 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 M2TS file is decoded and re-encoded as FLV. The conversion involves 4 steps: (1) your m2ts 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 flv 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 FLV file for your workflow. For the opposite direction, CocoConvert also supports FLV to M2TS conversion.
How to Convert M2TS to FLV
- 1
Upload .m2ts file
Select your M2TS file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .flv
Set FLV as the output format. The converter uses optimal settings based on the M2TS→FLV conversion profile.
- 3
Convert
The server-side engine decodes your M2TS file and re-encodes it as FLV. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .flv file. Multiple output files can be downloaded together.
What Happens When You Convert M2TS to FLV
Your M2TS video is transcoded — video and audio streams are decoded and re-encoded into the FLV container. This is a lossy process that takes time proportional to the video duration.
Your M2TS file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with FLV-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 FLV container and the file is saved

Should You Convert M2TS to FLV?
When to Convert
- ✓When you specifically need a FLV 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 M2TS to FLV
"I'll convert to FLV and then back to M2TS — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going M2TS → FLV → M2TS will produce a noticeably worse file than the original. Always keep your source file.
Frequently Asked Questions
What is the difference between M2TS and FLV?
M2TS is the Blu-ray disc transport stream format used for high-definition recordings. FLV (Flash Video) is a legacy streaming format — converting to MP4 is recommended for modern use. Full Name: M2TS uses Blu-ray Transport Stream, while FLV uses Flash Video. Compression: M2TS uses Lossy, while FLV uses Lossy. Color Depth: M2TS uses 8-bit, while FLV uses 8-bit.
Does M2TS to FLV conversion affect quality?
M2TS uses lossy compression, and so does FLV. 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, M2TS or FLV?
M2TS uses lossy compression. FLV uses lossy compression. The better choice depends on whether you prioritize file size or quality.
How long does M2TS to FLV 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 M2TS or FLV better for long-term storage?
Both formats use lossy compression, so consider keeping your original source file for long-term storage.
