What is a .MSV file?
Everything worth knowing about Sony Memory Stick Voice File.
An MSV file is a Sony proprietary voice recording made by early-2000s ICD-MS series IC recorders that stored audio on Memory Stick media. Standard players like Windows Media Player and VLC cannot open it. The original Sony Digital Voice Player software is the primary tool, though it is legacy and may not run on Windows 10 or 11. Converting to WAV or MP3 first is usually the most practical approach on a modern PC.

Is my .MSV file uploaded to a server?
No. Your .MSV file is converted for you. The converted file is created in memory,.
Why is conversion slower than desktop software?
Browsers give web pages a single CPU core for this kind of work and no hardware video encoder. Short clips convert in seconds; for long 4K films a desktop app like HandBrake is faster. Use Start and Length to convert just the part you need.
Which output format should I pick?
MP4 plays on every phone, TV and browser. WEBM is an open format that's great for the web. MP3 keeps only the sound. MKV (no re-encode) is instant and lossless, but only changes the container.
Can I keep all audio tracks and subtitles?
The MKV (no re-encode) option copies every track as-is. MP4 and WEBM keep the first video and audio track, which is what most players use.
Why can't some files be converted?
Files protected with DRM (for example purchased iTunes .m4p songs or some .wmv rentals) are encrypted. We can show what's inside, but nobody can convert them without the key.
