What is iSCC?

inno Screen Capture Codec(iSCC) is the most optimized codec for screen recording. This codec offers you a higher compression and faster speed compared to any other codecs even the most popular one, TechSmith Screen Capture Codec(TSCC).

iSCC can be used not only with liteCam and CamVerce but also with screen recording software(AVI file type) from other companies such as Camtasia Studio, CamStudio, HyperCam and etc.


Compression rate comparison

We have compared the compression rate with number of other popular codecs. These graphs are not displaying all the files used in this test and it shows 0% for negative compression rate(bigger file size than the original file).



- Supports both lossless compression for screen recording and lossy compression for maximum compression

- Faster compression speed for real time recording

- Provides Video for Windows codec and DirectShow Filter based codec

- iSCC Encode Filter: DirectShow Codec(Encoder)

- inno Screen Capture Codec: Video for Windows Codec(Encoder/Decoder)

- Complete x64(AMD64/EM64T) 64bit operating systems support

- Now supports RGB16, RGB24 and RGB32


System Requirements

- 64 bit OS support. Finally, a reliable codec that works on 64 bit OS.

- iSCC 32bit edition : Windows 2000, XP, Vista or 7

- iSCC 64bit edition : Windows XP, Vista or 7 x64 Edition

- Minimum system requirements to run Windows Media Player



iSCC is not a recording/converting software, only the codec will be provided. There is no decoding limitation for the evaluation version, but "Produced by iSCC" will be displayed on the upper right hand side while encoding using the evaluation version.

Features for screen capture codec

Computer screen capture codec not only records the computer screen but is also used for editing the recorded videos as well as for distributing the edited videos. These are the must-have features that screen capture codec’s should have:

- Recording: This task takes a lot of system resources, so less system resource/memory usage and faster encoding speed if better.

- Editing: faster decoding/seek speed is better to move between frames quickly.

- Distributing/Exporting: Smaller file size if better. However, you may experience destroying or smudging the text if you are using a lossy codec. Codecs with less text smudging are better if you are using a lossy codec.


iSCC Features

  • iSCC performs the most optimized tasks through various configuration settings.
  • - You can set for faster encoding when you’re recording. This will minimize the system load.

    - You can minimize the file size by changing the Quality settings when you’re exporting.


  • Fully Supports 64Bit environment.
  • - iSCC is one of very few codecs that support 64 bit operating systems which will be widely used when Windows 7 comes available.


  • Supports Video for Windows and DirectShow Filter based codecs.
  • - iSCC enhances the compatibility between multimedia applications by supporting both Video for Windows and DirectShow Filter based codecs where most codecs support Video for Windows environments only.

    - Generally, Video for Windows based codecs cannot be used in any DirectShow applications on 64 bit OS. iSCC provides DirectShow Filter based codec for 100% compatibility.


    Lossless and Lossy Compression features only on iSCC

    lossless compression used in iSCC means no change in screen quality from the original video. The following pictures show you the screenshot taken from a video encoded with one of the most popular lossy codecs, Microsoft MPEG-4 Video Codec V3, WMV, Xvid and iSCC. You can see that the video encoded with iSCC didn’t lose any quality.


    [iSCC: Quality 6, Lossless compression] iSCC


    [Microsoft MPEG-4 Video Codec V3: 345kbps, Lossy compression] Microsoft MPEG-4 Video Codec V3


    [Windows Media Video 9: 529kbps, Lossy compression] Windows Media Video 9


    [Xvid MPEG4 video codec: 767kbps, Lossy compression] Xvid MPEG4 video codec


    If you use a lossy codec for screen capture, it causes text smudging. You can change the Quality settings in iSCC which lowers the screen quality without smudging text. You can see different quality settings applied from the pictures below.


    [iSCC: Quality 6, Lossless compression] iSCC


    [iSCC: Quality 5, Lossy compression] iSCC


    [iSCC: Quality 4, Lossy compression] iSCC


    [iSCC: Quality 3, Lossy compression] iSCC


    [iSCC: Quality 2, Lossy compression] iSCC


    [iSCC: Quality 1, Lossy compression] iSCC


    [iSCC: Quality 0, Lossy compression] iSCC


    As you can see from the pictures, iSCC encodes and leaves text recognizable. This Quality settings can significantly reduce the quality of the video, so check the encoded video to make sure it’s viewable. We don’t recommend going more than 2-3 steps below High.

    iSCC installation

    Double click the iSCC installation file and you will see the iSCC installation screen.


    Click the Next button to continue




    The next screen will display the Software License Agreement. Read it through and select I accept the terms of the license agreement and click the Next button to continue the installation.




    You can enter your Name, Company Name and Serial Number in the next screen. If you are installing an evaluation copy, leave the Serial Number field as "Evaluation" (keep in mind that "Produced by iSCC" , will be displayed when using the evaluation version. )




    If you have purchased a registered copy and enter the serial number and click the Next button.




    Click the Install button to install iSCC.






    Click the Finish button.




    You will see a folder named innoheim > iSCC from the Start menu after it's successfully installed.

    After iSCC is successfully installed, you will be able to play AVI files encoded with iSCC.




    There are two components in iSCC; Video for Windows(VFW) based inno Screen Capture Codec and DirectShow Filter based iSCC Encode Filter. You can use inno Screen Capture Codec most of the time, and select iSCC Encode Filter on DirectShow Filter based programs if inno Screen Capture Codec is not supported.


    Default settings will work on most cases. However, you may change the settings if you wish.


    The following picture shows you the dialog box where you can configure custom settings.



    [inno Screen Capture Codec-32bit edition]


    [iSCC Encode Filter-32bitedition]



    [inno Screen Capture Codec-64bit edition]


    [iSCC Encode Filter-64bit edition]


    Basic settings for DirectShow and VFW are identical. You can change settings for Comparison Level, Key Frame, Compression Control and Quality. You can always click the Default button to reset to the default settings.


    - Comparison Level: Steps for comparing between frames. More frame comparison will be performed if you set it High. Generally, you get higher compression rate if you set it High.


    - Key Frame every *** frames: Setting intervals between key frames. If you set the interval value smaller, you get a faster seek speed but the file size will get bigger. You can enter between 0-1000, and only the first frame will be set as key frame if you set it to 0.


    - Compression Control: Fast means faster compression speed and lower compression rate. High means slow compression speed and higher compression rate.


    - Quality: The default value is High and it's lossless compression. If you change it to Low, your system may slow down so it's not recommended for real time recording. You can change the Quality value a step at a time to determine the appropriate value for your recording.

    You will be able to reduce the file size if you set Comparison Level to High, Key Frame to 300 and Compression Control to High when you are doing the final conversion after the editing. It is recommended to set Quality to High, but you can reduce the file size by reducing the Quality value.


    As mentioned earlier, change the Quality settings only for file conversion. However, change the Quality setting one or two step lower if your best interest is in minimizing file size. If you set it even lower, the video quality will be significantly reduced. Please note that it takes 20-30% longer encoding time if you change the Quality settings from High.


    If your system has faster than dual core CPU and good video, audio card, you may be able to reduce the Quality settings 1-2 level lower and apply it to real time recording. Please test record first when you change the settings.
