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
http://www.compression.ru/video/ls-c..._codec_en.html
But after using this in Video Options|Compressor, I get the following
behaviour:
- The immediate playback in CamStudio is corrupted (many coloured
stripes)
- 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
