Converting nsv files (HowTo)


 
Anyone know how to convert captured .nsv files (NullSoftVideo stream) into something more useful, preferably cross-platform? Like a Quicktime .mov, mpeg 2 in a common codec, avi, or as a last resort .wmv?

Thanks,

Cam

  • Convert NSV files using Mencoder (Freeware/Windows, Linux, MacOS)
    Mencoder is a free video conversion tool. It is a part of Mplayer. You may download it from
    http://www.mplayerhq.hu/

    You will also need VP codecs. DLLs for Windows can be downloaded from
    http://geocities.com/mplayerdll/

    Conversion process
    a. Download and install Mplayer.
    b. Find "mencoder.exe" (it resides in the same folder as Mplayer).
    c. Download the necessary VP codecs (On2 VP3, On2 VP6, On2 VP7).
    Extract the codecs (*.dll) into the mencoder's folder.
    d. Create a batch file (.bat) with the following content and run it:
    Quote:
    mencoder "input.nsv" -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2000 -oac mp3lame -lameopts preset=standard -o "output.avi"
    In the example above the file input.nsv is converted to the output.avi, the latter will be encoded with MPEG-4 video codec and MP3 audio codec.

    Instead of using the batch file, you may open an MS-DOS prompt:
    a. Click "Start" -> "Run..."
    b. Type cmd.exe
    c. Click OK

    Then type something like
    Quote:
    mencoder "input.nsv" -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2000 -oac mp3lame -lameopts preset=standard -o "output.avi"
    After converting files don't forget to test them with a player like WinAmp or Media Player Classic.

    Note:
    Before launching mencoder from the MS-DOS prompt, navigate to the folder with mencoder.
    Your input.nsv should be in the same folder as mencoder.exe.

    You may use different setting like filenames, audio and video codecs if you like.
  • Convert NSV files with NSV Demuxer (Freeware/Windows)
    You will need
    1. NSV Demuxer
    http://www.scvi.net/download/download.php?nsv_demux.zip
    2. K-Lite Codec Pack (you may install VFW On2 VP3, On2 VP6, On2 VP7 video codecs using alternative ods as well)
    3. AVI-Mux GUI
    http://www.hollmen.dk/articles/nsvtoavi.htm#AVIMUX

    Conversion process:
    1. Use NSV Demuxer to demux the file:
    Quote:
    NSVD.exe -n input.nsv -a output_video.avi -w output_audio.ext
    2. Mux output_video.avi video file with output_audio.ext audio file created with NSV Demuxer into AVI file using AVI-Mux GUI:
    a. Drag and drop the video and audio files ("output_video.avi" and "output_audio.ext") into the AVI-Mux interface.
    b. Select the AVI file, and click "Generate data source from files". Then click "Save", and choose a name for your .AVI file. When the program has finished processing, close it.
    3. You may also convert the .AVI file from the step 2 with TMPGEnc or VirtualDub to .AVI file with a video codec like Xvid or x264.

Re: Converting nsv files (HowTo)


 
Hi,

I tried the method using Total Video Converter. Version 2.6 and 3.0Beta, but no luck.

When I try to load the *.nsv file the NSV format does not show in the
dialog for supported formats and when I still try to load it I get
message "Can't open file"

Any comment will be appreciated.

Re: Converting nsv files (HowTo)


 
I tried looking for way to convert .nsv files but I wasn't interested in paying for a converter and there aren't any freeware ones out there. I tried one method but it didn't work. However there is one method that will work it takes a bit or work though. I just found a place where I can download .nsv files. I want to put them on DVD but I need to convert them first. Since I knew of no way to convert them, I decided to use this screen recorder (ZD Soft Screen Recorder) and it worked! I played it in Winamp first and recorded it. If you want more information on how to do that reply to this thread.
