CamStudio codec problem

Discussion in 'Amateur Video Production' started by Terry Pinnell, Mar 1, 2008.

  1. Can anyone help me isolate this problem please? I use CamStudio 2.00
    for screen captures. In the past I've accepted the default codec,
    'CamStudio Lossless Codev v 1.00' without thinking much about it. I've
    tried DivX a few times, but the quality after import into my editors
    (Magix MEP, Womble) and rendering to DVD MPEG was rather poor.
    Recently I installed a new codec, based on the following advice (can't
    find the origin right now):
    "Use the MSU Screen Capture Lossless Codec as it creates smaller files
    than the Techsmith Screen Capture Codec

    But after using this in Video Options|Compressor, I get the following
    - The immediate playback in CamStudio is corrupted (many coloured
    - Same result when I play it after importing to Magix MEP.
    - Yet it plays fine in VirtualDub. File|Information reports:
    Frame size, fps (us per frame) 1044x662, 25.000 fps (40000 uS)
    Length: 178 frames (0:07.12)
    Decompressor: MSU Screen Capture Lossless Code
    Number of key frames:
    Min/avg/max/total key frame size: 1267172/1267752/1268333 (2477K)
    Min/avg/max/total delta frame size: 0/173/7994 (30K)
    Data rate: 2883 kbps (0.17% overhead)

    - If (without understanding) I use Gspot 'Proposed Codec Solutions and
    Tests', steps 1 & 2, I get the following report, unintelligible to me:

    (Src)-->>--(A)-->[Avi Splitter ]>--(B)-->[VFW:MSU Screen Capture
    Lossless Codec v1.2 ]>--(C)-->[Video Renderer ]
    Failed to create instance of Avi Splitter. CoCreateInstance() failed.

    Video Render OK. Use [3] to play.

    Here's what Gspot reports:
