Situation. M2TS is the Blu-ray transport stream container for HD video. Solution: a AVI, produced below. Repackaging a M2TS file into AVI is one of the fastest video jobs there is. When the codecs already match the target container specification, the bytes are literally copied across — no re-encoding, no quality drop, no long wait. Upload above and watch the progress bar usually fly. One more beat. M2TS is the Blu-ray transport stream container for HD video. Receiving format: AVI is the legacy Microsoft Audio Video Interleave container from the 1990s.
Blu-ray MPEG-2 TS
Source formatM2TS is the container used on Blu-ray discs and AVCHD camcorders.
AVI Video
Target formatAVI is a legacy Microsoft multimedia container that stores audio and video data. While largely superseded by modern formats, it remains widely recognized and is produced by many older devices and screen recorders.
Why convert M2TS to AVI
AVI Video is better supported than Blu-ray MPEG-2 TS across web uploads, social networks and consumer devices. Converting trades the niche advantages of M2TS for broad playback and fewer "file type not supported" messages. Stream copy (when codecs match) keeps the video bit-identical to the source.
HOW TO CONVERT
M2TS → AVI
Upload the M2TS
Drop your M2TS onto the uploader. Files up to 100 MB run on the free tier without registration.
Stream-copy or re-encode
FFmpeg probes the codecs; if compatible, it stream-copies (no quality loss). Otherwise it transcodes at matching bitrate.
Download the AVI
Fetch the converted AVI as soon as it is ready. Both files auto-delete within two hours.
Common Use Cases
Social media uploads
Twitter, Instagram, TikTok and LinkedIn accept AVI directly; M2TS is typically rejected or transcoded with unpredictable quality.
Smart TV and Chromecast
Many TVs play AVI out of the box — M2TS often shows up as "unsupported format" or skips audio tracks.
iPhone and iPad playback
iOS Photos, AirDrop and native Safari decode AVI without third-party apps; M2TS frequently needs VLC.
Web video embeds
HTML5 <video> tags play AVI universally; M2TS often requires clunky object-tag fallbacks or server-side transcoding.
Quality & Compatibility
Stream-copy is bit-perfect: when the codecs inside M2TS match what AVI can carry, the frames are copied across without re-encoding and the output is visually identical to the source. When transcoding is required, we target CRF 20–23 H.264 — visually transparent for most content — and keep audio bitrate at 192 kbps AAC.
Tips for Best Results
- Stream-copy beats re-encoding by orders of magnitude — check if your M2TS already uses AVI-compatible codecs before picking Advanced settings.
- For social uploads, 1080p at 30 fps strikes the best quality-to-size ratio; 4K is often downscaled server-side anyway.
- Keep the M2TS if you plan further editing — transcoded AVI is fine for final delivery but not for intermediate edits.
Frequently Asked Questions
Frequently Asked Questions
Only when it has to. If the codecs inside M2TS (usually H.264 or H.265 for video, AAC for audio) are accepted by AVI, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
