Last updated
Quick answer: To convert NUT to OGV, add the NUT file to the iHateFiles NUT to OGV converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. NUT is a format most software has stopped opening. OGV is not.
Should you convert NUT to OGV?
Yes. NUT is a format most current software no longer opens, so converting it is the reliable way to keep watching it. OGV is a reasonable target; MP4 is the safest.
The picture is re-encoded
A NUT usually holds whatever codec FFmpeg was asked to put in it. This writes Theora video with Vorbis sound into the OGV. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from NUT artefacts rather than the original.
Expect a larger OGV
OGV uses Theora video, an older and less efficient codec than a NUT normally holds. Matching the look takes more bytes, so the file grows. Do it for compatibility with whatever needs OGV, not to save space.
Extra tracks may not survive
A NUT can carry several audio tracks. OGV holds one picture and one sound, so this conversion keeps the main video and the first audio track. If you need the subtitles, save them first with Extract Subtitles.
Where the OGV will play
OGV plays on Firefox, Chrome and VLC, but not Safari or most phones.
NUT and OGV side by side
| NUT | OGV | |
|---|---|---|
| Inside the file | whatever codec FFmpeg was asked to put in it | Theora video with Vorbis sound |
| Compression | Lossy | Lossy |
| Carries sound | Yes | Yes |
| Plays on | Needs converting first | Firefox, Chrome and VLC, but not Safari or most phones |
| Here | Read only | Read and write |
What usually goes wrong
About the NUT. If you have a NUT file it almost certainly came out of a script using FFmpeg defaults, rather than from any deliberate choice.
About the OGV. At the same file size Theora looks clearly worse than H.264, so re-encoding an old OGV will not recover detail that was never captured.
How to convert NUT to OGV
- Add your NUT file. It is read from your disk and stays there.
- Check the settings. The output format is already set to OGV.
- Press convert and the OGV file is saved back to your device.
Questions
How do I convert NUT to OGV?
Open this page, add your NUT file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this NUT to OGV converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to OGV lose quality?
OGV is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several NUT files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
