Video Options Dialog

(From the main menu, choose Options->Video Options)

Setting the video options allows you to optimize your video recordings by choosing between the file size, quality and frame rates of your video files.

Auto Adjust
Use the Auto Adjust settings to set the Key Frame Rate, Capture Rate and Playback Rate automatically through the slider. Shift the slider to the left to increase the frame rate and to the right to reduce file size. If the slider is situated at the right of the Time Lapse indicator, it means you are creating a time-lapse movie.

In Time Lapse mode, Desktop Screen Record 5 will usually capture a frame only after a long period of time. (Example: after every 30 seconds). However, during playback, the frames will be displayed more quickly. (Example: at 20 frames per second).

Compressor
The Compressor select-box allows you to select the encoder for your AVI file. An encoder compresses your AVI files to make them smaller in size and cause them to play faster. The default setting is the MS Video 1 compressor.

Configure
Click this button to configure the parameters of your selected compressor. The parameters for each compressor is different and some settings will cause Desktop Screen Record 5's performance to degrade or behave unpredictably. For some compressors, clicking this button will not have any effect.

Quality
The quality setting determines how nicely your picture is saved. A lower value means a lower picture quality but also a smaller file size. Only some compressors use this value.

Set Key Frames Every
This setting specifies the keyframe rate. When a frame is saved in an AVI file, they can either be saved as a full frame, or only partially as a difference to the previous frame. The keyframe rate specifies how often full frames are written to the AVI file. A high value means you can fast forward/rewind to a particular frame in your movie much faster. But it also means a higher file size.

Capture Frames Every
This field determines the input frame rate. It dictates how long the Desktop Screen Record 5 will ¡®sleep¡¯ after capturing each frame. One millisecond is 1/1000 of a second.

If you set this to a large value (for example 1 hour, or 3,600,000 milliseconds), you practically create a time-lapse movie. Desktop Screen Record 5 will actually i®sit and watch for activities on the screen that takes a long time to occur and take a snapshot (say, only once every hour).

Playback Rate
This field determines the output frame rate. It specifies how many frames are played back per second. A higher value means a smoother playback. Typical values of 20 - 30 frames per seconds are adequate for most purposes.
