*.nmv video (HDMS)

[Danzz]

Does anyone know how to convert *.nmv videos to an mpeg type format? The nmv video extension comes from HDMS (Hard Drive Music Systems) for music videos.

Any advice would be apreciated

Pete.

hdms is
Audio Compression MPEG1/MP3 at 256 Kbits/s (6:1 compression) required for CD quality stereo sound.
Video Compression MPEG1 at 2 Kbits/s bit rate.

can you open it in any tools like virtualdub or tmpgenc?

Thanks for the info. I can not open these .nmv files in virtualdub or tmpgenc. I can not even open the files to view the video properties of them.

Is there any other special codecs I need installed to open / play these?

Thanks again,
Pete

*.nmv's were originally encrypted using a 256bit AES algorithm. Newer files are encrypted with a 256 bit blowfish algorithm, but are very hard to hack.

You need to try a brute-force program to decrypt the *.NMVs or better yet write your own software using an attack method such as a dictionary attack to find the cipher key.
