The second interesting possibility is a visual cursor options when recording video. You may change "hot" keys for these operations. " F9" means stopping video capturing and saving an avi file. To do this, in " Options" menu select " Keyboard Shortcuts".īy default " F8" key starts/terminates video capturing process. Click "Configure".įirst, it is the possibility to set up "hot" keys for starting, pausing and stopping video capturing. We can also view the compression algorithm configuration. The lowest parameter " Time Lapse" is also left as it is " Max Framerate" (as shown at the picture). For a video captured from computer screen the value of " PlayBack Rates" equal to 10 frames/second is also enough. It is known that a human eye cannot perceive more than 25 frames per second. frames/second" sets the frequency at which frames will be shown in the final file. The second parameter from the group " Framerates" - " Playback Rate. Creation of frames every 100 milliseconds gives us 10 frames per second which is quite enough for showing video illustrations.

The value of " Capture Frames Every" equal to 100 milliseconds is usually enough, because we are not going to record dynamic scenes of an action movie or Formula 1.
It indicates intervals of time, through which frames will be captured from the screen. The next parameter is " Capture Frames Every. The parameter value 200 is in most cases enough for getting video of good quality. If the value is too large (for example a key frame is created every 500 frames), the size of the final file will be small, but the quality will be poor. If this is done too often (small value of " Set Key Frames Every"), the video quality will be very high, but the final file size will be too large.
#CAMSTUDIO DISPLAY MENU UPDATE#
There are different ways to prevent this, but the easiest one is to update a key frame from time to time. However, a key frame should be updated from time to time, so that the quality of video doesn't become worse on the 1000th frame from the key frame because of the inevitable information loss during compression. This approach allows to considerably reduce the size of video files. Instead, some initial frame (key frame) can be remembered, after that pixels that have changed as compared to the previous frame are detected. It means there is no need to describe each video picture pixel for each frame. It was noted that the larger image part stays unchanged when one frame is replaced by another.
#CAMSTUDIO DISPLAY MENU INSTALL#
That's why I recommend to install a small free program CamStudio, using which you can easily record video from screen:Īs distinct form video tape recorders that recorded on a tape each video frame, modern algorithms of video compression use another principle for the sake of size economy. Not all users want to use paid programs for recording from computer screen. Files in FLV format are created by the video service of our forum, though source files for uploading to our website can be in AVI, MPG, WMV or directly in FLV. But there is a universal method - recode clips into a flow format *FLV that can be easily viewed in any browser supporting Adobe Flash version 8.Įxactly this video format is used by the video service of our forum for showing video clips. Most of existing formats are not suitable to be published in the Internet because of compatibility problems and available codecs. The article describes the ways of recording video clips for publishing on munity website at high quality and acceptable size without unnecessary actions. Nowadays there are so many different video formats and programs for recording video clips, that it is a kind of problem even to choose such a program.
