Known Bugs and Limitations
Video/Audio sync and the Capture Frames Every __ milliseconds and Playback Rate settings:
To get the Capture Frames value, divide 1000 (1 second = 1000 milliseconds) by the Playback Rate.
By default the playback rate is 20 and the Capture Every is 50, because 1000/20=50.
A playback rate of 10 would need the Capture Every set to 100, because 1000/10=100.
A playback rate of 25 would need the Capture Every set to 40, because 1000/25=40.
CamStudio currently only accepts whole numbers for the options here, any decimal values will simply be ignored (eg: if you entered 33.333 for your playback rate, CamStudio will store it as 33).
If you want to record video and audio at the same time, you will need to have values for the capture and playback rate with a product of exactly 1000 (eg: 100 for the capture frames and 10 for the playback as 100*10=1000).
A capture frames value and playback rate that do not multiply wholly into 1000 (such as 33 and 30 mentioned in the example above) will cause the audio and video to become out of sync (33*30=990, not 1000).
Installation [versions 2.0, 2.5]
[This issue is being worked on currently in version 2.6 beta to make it compatible with Vista and Windows 7]
"This application failed to start because MFC71.DLL was not found. Reinstalling the application may fix the problem."
If you receive the above error message and reinstalling does not remedy the issue, try downloading MFC71.dll and copying it into the folder where you have CamStudio 2.0 or 2.5 Beta installed (eg: "C:\Program Files\CamStudio\").
If you still receive the above error message when launching CamStudio, you can try copying the MFC71.dll into your C:\Windows\System32? directory then rebooting your computer.
Region > Window
[This issue no longer applies to the 2.6 Beta version - it applied only to 2.5]
When using the "Region > Window" capture setting, the captured area will have 1 extra pixel added to the right and bottom of the capture area. For example, if the window was 960x720, the captured area would be 961x721. Although these extra lines can easily be cropped off, this may cause problems with certain video compressor codecs. A rough work around for this would be to set the window size to be 1 pixel smaller in width and height then that you desire to capture at (eg, if you wanted 960x720, instead set the window size to 959x719).
Similar to the "Region > Window" bug described above, the SWF Producer will also add an extra pixel to the width and height of videos being converted to SWF. A workaround is possible through the same means described above, reducing the dimensions to be 1 pixel less then the target resolution.
CamStudio currently cannot create avi files over 2GiB in size. Files over this size will likely be corrupted and difficult, if not impossible, to recover.
It is not currently possible to set just one keyboard shortcut to use with CamStudio. In order use the keyboard shortcuts, all of them must be set to different keys.
