audioConverting MTS to AIFF: what actually changes
MTS to AIFF is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .MTS and .AIFF each hold
.MTS is a video format built for playing, editing or re-encoding a clip, storing frames, bitrate and audio tracks. .AIFF is a audio format built for listening to or editing a recording, storing sample rate, channels and bitrate. Converting between them is a decision about which of those two jobs the result needs to do.
What changes when categories differ
This conversion keeps the sound and drops the picture: the audio track is decoded out of the .MTS container and re-encoded as .AIFF for listening to or editing a recording. Length, loudness and voice carry over; frames do not.
When this conversion is the right one
Reach for .AIFF when you need a file for listening to or editing a recording, starting from playing, editing or re-encoding a clip. If that is not what you are after, check what else .MTS converts to before committing to this target.
Tips for a clean MTS to AIFF conversion
Start from the original file
Convert the .MTS you started with, not an earlier .AIFF output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Video/mp2t becomes audio/aiff. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Length decides the time
Conversion runs in real terms on duration: a few seconds of media finishes almost at once, while a full-length .MTS takes noticeably longer. Upload once and let it finish rather than retrying.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge video files, split or compress the source first.
